4/7/2009 Re: cloudy water 4/8/09 Goldfish pH -05/15/08 Good afternoon, I haven't contacted you for some time, but you were all very helpful to me some time ago when I was having problems with my three goldfishes. Thank you once again for your help then; they are all currently happy and healthy! My question today is regarding raising the pH in their aquarium. It is currently far too low, around 6.5 - we have just moved house and the water is quite acidic. Although the pH is creeping up gradually I want to get it up and keep it up, preferably around 7.5. I have done some reading and have obtained various suggestions, from using bicarbonate of soda at every water change, to adding marble chips or crushed coral to the filter. There is also a recommendation in an article on WetWeb to use Lake Malawi salts. I am sure that any of these would be effective, but naturally I want to do the best thing for my goldies. I just wondered if any of you lovely people could offer some advice? Many thanks if you can and I look forward to hearing from you, Sarah <Hi Sarah. Very important this -- pH isn't the thing to worry about, it's carbonate hardness! What fish care about is that pH is stable. Yes, Goldfish prefer a basic pH (i.e., between about 7 and 8) but what really matters to them is that there isn't rapid pH decline between water changes. In fact, Goldfish can adjust to slightly acidic pH down to about 6.5, provided it doesn't go any lower and doesn't bounce up and down between water changes. So, the thing to do is ensure the carbonate hardness (which you measure with a KH test kit) is nice and high. Remember, carbonate hardness is the stuff the inhibits acidification by "mopping up" acidity. Anyway, that's where the Lake Malawi salts (and so on) come in. By adding these to the water, you send the carbonate hardness to around 5-10 degrees KH, and that's the thing that slows down the pH drop between water changes. And that, my friend, is what makes your goldfish happy as can be. The old school approach is to buy a bag of crushed coral of the sort used in marine aquaria, add them to the filter (in a filter media bag), and stick into a canister filter. The carbonate will dissolve into the water, and hopefully keep the carbonate hardness high and the pH level steady. Every few weeks you will need to clean the carbonate under a hot tap to wash away the slime, and maybe once or twice a year replace it completely. Adding Malawi Salts are an alternative approach that is perhaps more fiddly but is certainly more reliable and accurate. Malawi Salts can be purchased off the shelf or made at home for pennies. Cheers, Neale.> Goldfish -10/31/08 Re: Goldfish 11/2/08 Thanks for the advice. Now, you mentioned that if my water was too soft the bogwood would be a bad idea. Well I went out to buy a test kit and from what it tells me is that my aquarium water has a general hardness of 6 (107.4ppm), and a KH value of 3. I'm assuming that I have a soft water. <Indeed, this does sound like you have quite soft water. Goldfish actually prefer hard water, so anything you can do harden the water will be useful.> The thing is that I have some crushed coral in my hang on power filter (not a lot at all, just two cartridges of it) and I've been having a steady pH of 7.6. <These filter cartridges are pretty useless to be honest. Bacteria cover them within days, rendering any chemical filtration practically non existent. Much better to add a mineral salt mix to the water. Cheaper and far more effective. Use something like a half-dose of Rift Valley Cichlid salt mix, i.e., adding to a 5 gallon (20 litre) bucket of water: 0.5 teaspoon baking soda (sodium bicarbonate) 0.5 tablespoon Epsom salt (magnesium sulfate) 0.5 teaspoon marine salt mix (sodium chloride + trace elements) Don't do a massive water change all at once; instead just add these minerals to each new bucket of water you add during regular weekly water changes. That will gradually change the hardness and pH to something Goldfish prefer. If you still don't get the hard water you want, you can double this dosage without any problems. Throw away the stupid crushed coral modules in your filter and replace with filter wool or whatever to support biological/mechanical filtration, as you prefer.> Do you still think that adding a few pieces of the bogwood would be detrimental? <In soft water, yes.> I don't want a fluctuating aquarium. Or do you think that the crushed coral is doing its job? <Doesn't sound like it judging by your numbers. Goldfish want 10+ degrees dH, i.e., moderately hard to hard water.> By the way, would I ever need to replace the crushed coral, and does it lose its buffering capacity over time? <If put inside a filter, small amounts of crushed coral will be virtually useless within a couple of weeks, and all chemical media -- coral, carbon, Zeolite -- need to be replaced at least monthly even in the best of circumstances. These chemical media modules are mostly used as away to siphon money out of your pocket into those of the retailer and manufacturer. Their practical value in freshwater fish keeping is close to zero, and experienced freshwater fish keepers almost never use them. Carbon is another total waste of space, by the way. Big water changes, particularly if the water is treated with a chemical buffer mix as described above, will do a FAR better job of stabilizing pH and removing dissolved organic acids from the water. But water changes are free, so aquarium hardware manufacturers would much rather trick people into buying modules of carbon and crushed coral and Zeolite and other stuff they just don't need. Call me a cynic, but I'd sooner spend that kind of money on myself, not my fish tank.> Thanks so much. <Cheers, Neale.> pH problems, FW, Goldfish 1/14/09 Hi Neale, <Hello Midhat,> Thank you very much for your advice regarding the snail. Have a question regarding pH, have been getting variable reading of the pH. We have one 1.5 inches long red Oranda and 1 inch red cap Oranda in 20 gallon tank with a filter, live plant (Red Ludwigia) and a decoration rock. <Well, the Ludwigia won't last long. Putting aside the fact Goldfish eat plants, Ludwigia repens is a very difficult plant to grow. It needs a lot of light and a decent, iron-substrate. Plants aren't easy to maintain, and once they start dying, they pollute the water. I'd recommend you add no other plants to this tank other than cheap pondweed (Elodea or Egeria) that you allow the Goldfish to eat. When these plants start looking shabby, throw them onto your compost heap and buy some new ones!> Today in the morning checked the water it had a pH of somewhere b/w 8.5 - 9.0 according to the test strip, did a quick partial water change of 10% (didn't want to bring it down very quickly), another reading was taken it was 7.5, at once took a sample to LFS and got the water checked, turned out to be 8.4. At the pet store they gave me 'Neutral Regulator ' by Seachem to adjust the pH to 7.0 (whether high or low just brings pH to neutral value). <Would actually suspect the test kit is either [a] inaccurate or [b] difficult to read. Dip strips can be notoriously inconsistent. Some brands are better than others. Another factor can be the time of the day, though that depends on how strongly the plants perform photosynthesis. I assume you don't have strong lights, so this particular problem isn't likely.> My question is should I use it? <Will do no harm, provided you use precisely as instructed on the packaging.> As on your website it has been mentioned several times that no tempering with the pH should be done. <Broadly this is true. It's much better for people to get fish that "like" the local water chemistry, so that you don't need to mess about with pH or hardness. If you live in a hard water area (e.g., your kettle becomes furred up with lime or you need a lot of detergent in the washing machine) then it is very unlikely that pH will vary much between water changes. Hard water is really very good stuff for keeping tropical fish happy!> I also got a live pH monitor by Mardel and is showing the pH value of 7.4 continuously and bought new test strips (API) they are giving the value somewhere b/w 7.5 - 8.0. Tap water has the pH of 7.5. I am really puzzled by this, as never had any problems with the pH before. <Honestly, my gut feeling is that you aren't using the test strips right, or else they just aren't very reliable. The liquid test kits tend to be more consistent, even if they are marginally more difficult to use. In any case, try using the test strips every day for the next three or four days, performing the tests at precisely the same time, to factor out any daily variation. If the test results are essentially the same from one day to the next, that's really all that matters.> My fishes are not showing any signs of stress just some yawning on behalf of red Oranda. <If the fish aren't stressed, I'd not worry too much. If pH changes suddenly, fish quickly react, often gasping at surface or darting around the tank nervously.> Your advice will be greatly appreciated as don't know what to do, nothing is making sense. Thank you very much. Best Regards, Midhat <Good luck, Neale.> Re: pH problems... Mmmm, no. Goldfish sys. 2/11/09 Evening Neale and Mr. Fenner, <Evening!> Sorry for emailing you again and thank you very much for you advice. The WetWebMedia crew has set up an amazing website. Thank you every one for educating us. <I'm sure that Bob will be pleased to hear you say this.> <<Ah yes>> First some back ground information. We have a 20 g tank with two goldfishes, 1 red Oranda (1.5") named Goldie and other is red cap Oranda (1.15") named Luna, two filters (1 sponge filter and the other is HOB), one ceramic decoration, and one red Ludwigia (Neale your advice was amazing about it needing iron rich substrate, it is doing amazingly, has nearly tripled in size in one month and for some reason goldfishes don't like it). <Cool.> Our Ammonia, Nitrite and Nitrate are zero, GH=180, KH=180 and pH =8.0 (I know YIKES!). <The pH and hardness is just fine for Goldfish. Water quality is excellent. Don't start messing about with it! Just leave it alone.> Our tap water parameters are Nitrite and Nitrate zero, Ammonia=1.5, GH=120 (medium hard), KH=120, pH=8.2 (just increased recently from 7.5). After passing through the water softener and filtration system they are Nitrite and Nitrate=0, Ammonia=1.5, GH=b/w 0-30 and KH=0 and pH=6.0. <Too soft for Goldfish. Please DO NOT use water from a domestic water softener in an aquarium. These don't actually "soften" the water in the way aquarists mean it. What they do is replace the lime that furs up washing machines and pipes with salt. That's not a problem for a washing machine, but it's really bad for fish. It's why you don't drink from the domestic water softener tap, but from one that by-passes it. The ammonia level is too high as well, for no real reason I can fathom. So all in all, bad water. No further discussion required, because YOU ARE NOT putting this stuff in your fish tank.> We use tap water for the tank. I have been using Seachem's Neutral Regulator which keeps pH at 7.0, removes chlorine, chloramine and ammonia but it is not bringing down pH just introducing green spot algae problem b/c it contains phosphate based buffers. (We have premixed to-be-used tap water sitting out for a week with double the amount of Seachem but still it is at 8, going to triple the amount to see what happens). Is there any other product that you would recommend. <Why are you lowering the pH to 7? PLEASE, Goldfish LIKE HARD WATER. They like a basic pH around 7.5-8.0.> I need advice regarding the proper method to bring pH down. <For gosh sakes, LEAVE IT ALONE!> I have been doing daily 4 g water changes with the mixture of tap water and filtered water with Seachem's Neutral Regulator, it has Ammonia, Nitrite, Nitrate all zero, GH and KH=80 and pH=7.0, for past few days it has kept the pH at 8 otherwise if it is left alone goes up to 8.5. <Just use the plain tap water, the one with GH=180, KH=180 and pH =8.0 mentioned at the top. This is PERFECT for your fish. A 25% weekly water change should offset any pH changes before they get serious.> Should I continue with this strategy hoping it will eventually bring it down. Both the goldfishes are otherwise completely healthy with amazing appetite, just Goldie sometimes starts to yawn a little. I am a little at loss because aquarium setups are RedOx system but our moves in the opposite direction with each day pH going up a little. Haven't even changed the carbon filter in HOB this months. LFS also confirmed that pH is at 8 for both tap water and tank. <Fine.> I saw a similar question on pH FAQs and the answer was to get something that lives in similar water conditions b/c tinkering with the pH is never good but we don't want to give up our goldfishes they are like members of our family with their own distinct personalities and quirks, likes and dislikes and we are very attached to them. Sorry for it being such a long email. We would be really grateful for your advice. Thank you very much. <Happy to help.> Best Regards, Midhat. <Cheers, Neale.> Re: pH problems 2/12/09 Hi Neale, <Midhat,> Thank you very much for you advice, every where I read they said goldfishes live in water with the range of pH being 6.5 - 7.5 <Goldfish will survive here in England under ice for three months, and in the wild can tolerate up to about one-third the salinity of seawater. But neither of these things is "good" for them, and what you want to do is provide them with their favourite conditions. That is, unquestionably, hard, basic water. What in the UK we call "liquid rock"! Keep the pH around 7.5, and the hardness above 10 degrees dH ("moderately hard" on whatever scale you're using) and your Goldfish will love you.> that was the only reason that I started to change the pH. Now I wont try to mess up with it. <This is Neale's golden rule: don't mess with pH. Leave it alone! Unless you're an expert fishkeeper trying to maintain a very exotic species, it's ALWAYS best to let your fish adjust to your local water chemistry. Choose fish that LIKE your local water chemistry, and things are even simpler.> Thanks once more. Best Regards, Midhat <Happy to help. Cheers, Neale>
Re: Damage is Done. 8/6/07 Thank you Neale! I took readings across the board last night with the fantails' tank. 0 ammonia, 0 nitrites, 5-10ppm nitrates, pH 7.4-7.5. All good. I siphoned the gravel last night with very little trace of waste. <That all sounds ideal for goldfish. The only "extra" is to check the hardness. Goldfish like hard water and hate soft water, so if you have a water softener in the home -- don't use it! Give the goldfish "liquid rock" as well call it here in England. They love it!> I take readings in all my tanks on the weekends. <Good.> Maybe I did overdose with the flocculent. <Perhaps.> Regarding Malawi Bloat, I read that it could be caused by too much protein intake. Funny thing is I placed a cooked scallop with an elastic around a rock in the evening for the bumblebee cats. The mbunas tore the thing apart and the largest Mbuna was darting around the tank with half of it in his mouth. Oh God! Another mistake...Malawi bloat expected in the morning! <No-one really knows what causes Malawi Bloat; as I said last time round, salt is one of the suspected factors. It's most likely caused by different things in different circumstances, since it isn't a "parasite" but a symptom of organ failure. So like a fever in a human, can be cause by all kinds of things. That said, Mbuna are herbivores (more or less) so you want to balance the diet in favour of greens, not meat. A good meaty food is raw mussels. These contain a lot of marine algae, so are brim full of vitamins, and most fish love them. They're also very cheap, and best of all, among the most ecologically sound food animals on the planet.> He seems to be doing fine. Can't wait to move them from the 30 into a 55. I feel cramped just looking at them. <Cool.> I can't get my Plecos to nibble on lettuce or seafood. Any tricks or shall I just keep trying? I placed a romaine lettuce leaf in his favorite hang out last night and he ignored it. Zucchini the night before...didn't touch it (the guppies on the other hand are a different story). <Above all: patience. Vegetables contain mostly water and little protein, so don't pollute the aquarium. Even if they fall apart to green gunk, that stuff is harmless. So you can't really "overfeed" greens. Lettuce should be blanched first to break the cellulose cell walls. Plecs have adapted to eat algae (mostly) which is easier to digest than plant material. Hence we need to cook the plant material a bit to break the cells and make it more toothsome for the catfish. Vegetables like carrot, sweet potato, and zucchini often need to soak for a few days before the catfish catch on. But believe me, once they learn, they love it! Cucumber is another good food, though it contains little nutrient value and shouldn't be relied upon. As you've notice, many other fish enjoy their greens, too. It's often overlooked, but many of the fishes we keep are primarily or extensively herbivorous in the wild: cichlids, livebearers, barbs, characins etc all enjoy greens and will be healthier and have better colours when provided with it. Even predatory fish often enjoy some greens and will eat them at certain times of the year. Big predatory catfish take fruits and seeds during the seasons when fish are scarce. I have a pufferfish that enjoys cooked peas! So experiment, since you're unlikely to cause harm. Just wash, and perhaps blanche, any greens you have to hand. Obviously avoid anything potentially toxic, like chili peppers or rhubarb!> Not important you get back to me on this one. Thanks again, I so much appreciate your service. <No probs. Neale> Re: Damage is Done. 8/7/07 Neale, regarding hardening the goldfish's water, am I essentially reintroducing trace elements and minerals? Here's a product I located: Aqueon - Goldfish Water Renewal - 4 oz. Replace your goldfish aquarium water's trace elements with this simple formula. These essential compounds are necessary for fish and plant survival and become depleted over time. Special liquid restores these minerals and promotes health, color and vigor in your goldfish. Thanks again! Lisa <Lisa, sounds like garbagio to me, real snake-oil stuff. Anything that says "promotes" in the description gets a suspicious look from me, because that doesn't commit the product to doing anything either way. Kind of like when breakfast cereal says it "may help reduce heart disease". Yeah, right... Anyway, skip that stuff, and just to regular water changes. I've forgotten what your water chemistry was. If it's hard and alkaline right out the tap, then the goldfish are fine. If it's soft/acid, then fill one of the compartments in the filter with some fairly well pulverized crushed coral. That will raise the pH and hardness automatically without any further work. Periodically it'll need cleaning or replacement, but otherwise it's idiot-proof. What you're aiming for with goldfish is pH 7.5, hardness 10-20 dH General Hardness. Cheers, Neale.> Re: Fantails - pH and Hardness 08/17/07 Hi Neale, Sorry to be a pest. Just want to check in with you regarding the hardness and pH status of the fantails tank. The crushed coral has brought the pH to nearly 8.0. This exceeds their range of 7.6 (obviously) and the hardness has not increased from very soft. Am I endangering the fantails with this pH level? They are happy however I want to make sure this is the right thing. Thanks Neale. You are great. :) Lisa. <A pH of 8.0 is fine for goldfish. Here in England the pH of our very chalky water can get to 8.2, if not more, and goldfish positively thrive in it. It's important not to fixate on pH; it's the total dissolved solids that actually matter biologically, the pH is simply a useful first-pass approximation. Anyway, the calcium carbonate should be raising the carbonate hardness (that's the KH test kit). The dH test kit is measuring calcium oxide, which crushed coral doesn't contain so much of. The main thing here is that the dissolution of coral into freshwater is slow. If you're doing a 50% weekly water change, there will be only a modest increase in pH and hardness over time. The main reason for adding the crushed coral is to act as a buffer; if the water becomes acidic (which is normal in aquaria) the coral will prevent it. Dissolution is faster in soft/acid water than hard/alkaline water. So it's more an insurance policy than anything else. Bottom line, if the fish are happy, and the pH stays between 7.5 and 8, and the KH is around 5-15, and the dH around 10-20, your goldfish will be thriving. Cheers, Neale> Alkalinity & pH 9/20/06 Hi! <<Hello, Angi. Tom>> When I measure my pH it is normal for my goldfish (7.5)...but when I test the Alkalinity it is low (40 - 80 ppm). <<Okay.>> What should I use to raise the alkalinity and not raise the pH. I have Buff-It-Up (which didn't do anything), Stable 7.5, and Alkalinity Buffer (I think by Sea* something). This has me totally confused (I'm very new at this). Oh, my water is hard from the tap. If my pH is 7.5 which is alkaline why would my alkalinity reading be low? I am sooooooooo confused!!!! <<Easy to become confused by all of this, Angi. Perhaps it would be beneficial to use the term "basic" rather than "alkaline" to alleviate confusion between the terms alkaline and alkalinity. (Works for me!) Okay, "alkalinity" is a measure of a sample's ability to resist changes in pH (downward) in the presence of an acid. By the very same token, "acidity" is a measure of a sample's ability to resist changes in pH (upward) in the presence of an alkali, or base. In simple terms, it's "buffering capacity". Where, on either side of "neutral", a sample tests on the pH scale, at a given time, has no bearing whatsoever on its "acidity" or "alkalinity". This is borne out by what you've discovered, i.e. your sample tested "basic" (alkaline) but its buffering capacity (alkalinity) is low. Frankly, this isn't a stable condition since naturally occurring carbon dioxide in the air mixes with water to form carbonic acid. Additionally, there are other organic acid "dynamics" that take place in our aquariums that compound the problem. What this means, to you and others in this situation, is that your pH levels are in a precarious position. (Just what you didn't want to hear, right?) Hence, you need to increase your alkalinity (buffering capacity) in order to resist a plummet from a slightly basic pH level (7.5) to an acidic one (>7.0). Here's where things get stinky, er, sticky. It simply ain't easy to increase alkalinity without raising the pH levels. Sodium bicarbonate (baking soda) provides excellent buffering capabilities due to the "bicarbonate" element but, if not added very, very judiciously, can drive your pH up dangerously. The products you mentioned above are, to greater or lesser degrees, of questionable efficacy. Honestly, I would look to small but frequent water changes rather than trying to chemically alter your water parameters. In the time that you'll spend playing around with various "buffers" and "stabilizers" as well as the requisite parameter tests to ensure that you haven't screwed up somewhere along the line, you could have, easily, performed a simple water change. In the long run, you might find yourself acclimating your Goldfish to pH levels outside of the "ideal" but, many credible sources suggest that you're better off keeping your fish at your tap water parameters than to "artificially" rearrange them.>> Thanks for you time. Angi <<Hope this helps somewhat, Angi. Best of luck. Tom>> Re: Alkalinity & pH 9/20/06 Thank you sooooo much Tom! <<Oh, stop. You'll make me blush.>> Frequent water changes is exactly what I'll do (I sort of enjoy it anyway). One little question....when I'm doing like a 50% water change and gravel cleaning, would it be best to remove the fish to a bucket of the original aquarium water? <<Angi, you don't really want to go with a 50% water change. That falls into the "massive" range. Keep it to about half of that and you'll be "golden".>> They are constantly sucking on my arms!! LOL!!! <<They like you, Angi! Nothing like some good fish kisses. :)>> I have 2 tanks (29 gal with 2 Oranda -- about 4" body size not counting fins)(40 gal with 2 moors and 2 Ryukins --- about 2" body size). I've decided to get rid of the gravel in both tanks. It's a real pain trying to feed them because the only ones who see the food coming are the Ryukins. The rest have to try to get what has fallen between the gravel (1/2" gravel)....so the gravel is outta of here! <<Oh, they'll scavenge, anyway. Won't be as much fun for them but, it'll be a whole lot easier on you!>> Take care and thanks soooooooooo much again!!! Angi <<You're most welcome, Angi. Tom>> Re: My new goldfish ... lessons re life 6/30/06 Hello again, <<Hi, Kenzi. Tom again.>> I got my goldfish from my neighbor, but the fish didn't belong to them. They just volunteered to find new homes for them. <<Nice enough thing to do.>> Before the fish were transferred to them the fish were treated very poorly, and were already not in very good health when I received them (4 of them had died earlier that day). So unfortunately the bigger of the two (Gouda) died this morning. <<This is very sad to hear. I wish it was a rare occurrence but, unhappily, it's not.>> I had not purchased a big enough tank yet and was temporarily keeping them in a fish bowl. I am sad to say that is was definitely not big enough but I didn't have anything else and we absolutely couldn't go shopping. I didn't have the time to let the tank cycle, me getting the fish was very short notice and I didn't want them to stay in that bag very long. <<I understand completely. Well, let's see if we can save the one you have. If the worst does happen, we'll certainly leave you with enough information to make a successful run at the hobby when you're ready. :)>> I have researched cycling and it is still a little confusing. <<It can be a little confusing but don't let the "science" of it frustrate you. Think of it this way. You don't have to know how a computer works in order to use one.>> When I researched cycling, it said not to use goldfish, so how can I cycle for my goldfish? <<I can clear this one up for you rather easily. Many people will use fish, often Goldfish, to "seed" a new aquarium with a source of ammonia so that the cycling process can take place. We advocate "fishless" cycling here at WWM rather than using live fish for this purpose. My guess is that you ran across cycling information that recommends against using Goldfish - an example - to start the process. Just a coincidence that the article cited Goldfish, which happens to be what you have.>> Also, it says every three days I need to empty 15% of the water replacing it with tap water, exactly how do I do that? <<First, you need to get a bottle of dechlorinator from the pet store. There are many to choose from but the main thing is that it needs to remove chlorine/chloramine from the tap water. I use NovAqua Plus (Kordon's), for example. Okay, here's an easy way for you to accomplish the changes. Figure out how much water is in the bowl. A good guess will suffice. Since there are 16 cups of water in a gallon, 2 1/2 cups of water is 15% of a gallon. For each gallon of water in the bowl, take out 2 1/2 cups of water. Now, take another large bowl and fill it with tap water and add some of the dechlorinator (about a half a cap full from the bottle will be more than enough). Let this water sit for about 5-10 minutes or until it's clear again. Use your measuring cup to put the same amount of new water into the bowl as what you removed and you're done.>> I am assuming that when I switch my fish into it's new (bigger) tank I will be able to cycle properly and use the water it's in now as it's "store water." <<Provided the current water has cycled properly, yes.>> Also, I am not sure if I can have a filter. <<For the bowl or, for the new tank? On the new tank, this would be imperative since this is where the majority of the beneficial bacteria reside.>> Instead of having a filter could I just clean the tank more often and if I can, how often should I change it? <<I'm sorry to say that, without a filter on the new tank, your chances of keeping your pet alive and healthy for long wouldn't be good. You'd be testing the water constantly and, even then, you'd end up with ammonia/nitrite "spikes" that would doom your fish.>> I do not have a testing kit either, do you think I could get them at Wal Mart? <<Yes. Look for the Aquarium Pharmaceuticals Master Freshwater Kit, if possible. Easy to use and as accurate as you'll need for now.>> Ok, I think that is about it. I hope it is still useful once you have replied to my email, because my fish is still gulping for air and I am not sure if I can put it in a bigger container just for tonight. Well, I guess you can't help me with that I will try to research it before I go to bed. Well, thanks for the help, I'm sure Feta will appreciate the help, too. <<When you go to Wal Mart, look for a large Tupperware/Rubbermaid storage container. They're pretty cheap and work quite well for housing fish in an "emergency". So, dechlorinator? Absolutely. Test kit? Yes. Storage container? A very good option. Continued research? Most important of all!>> Sincerely, Kenzi <<My best and good luck. Tom>> Goldfish bubbles 1/19/06 Hi. My name is Elizabeth and I have a question about my goldfish, Schroder. I recently set up a bigger tank for him (5 gallon vs. 1 gallon), being careful to let it run for a day and put all the requirements in it to help stimulate good bacterial growth. He's been in it for about a week now and he has started to make a lot of little bubbles at the top, kinda like a Betta would for a nest. However, I read on your website that goldfish don't make nests (unless I misunderstood the response). I'm just wondering if I should be worried or not. Thanks for any help you are able to give!! Elizabeth <Can be worrisome... the bubbles are likely the result of excess slime/mucus from the goldfish... combining with air, persisting... An indication of "not-ready" conditions in the water/system. Please read here: http://wetwebmedia.com/FWSubWebIndex/fwestcycling.htm and the linked files at top. I would add the old water if you still have it, to the new tank... feed very carefully, and get/use ammonia, nitrite test kits... and BioSpira. Bob Fenner> Green Water 1/21/05 Hello. I have a 29 1/2 gallon fresh water tank that holds 7 fish ranging from different Oranda's, fancy tail gold fish, etc. (all of the goldfish family). About a month ago, I thoroughly cleaned out the tank because of the extreme amount of luminescent "green" water/coloring, to almost the point of not being able to see through the tank. Less than 2 weeks later, the "green" stuff came back. I asked my local pet store and they recommended changing 50% of the water. So I did. (maybe more than 50%). Only to find now that the growth of this green stuff had increased more rapidly. 1 week later I had to change most of the water again. I again consulted the local pet shop, and they recommended a couple snails, along with turning the lights off for approximately 12 to 14 hours a day. It is now not even a week later, and I can barely see through the tank. I have had most of these fish and the tank for about 3 years, and have never encountered this before. I have searched the net to find answers to no avail. This is my first "big" aquarium and I am not too knowledgeable on all the aspects of an aquarium this size. Come to think of it...about a month ago I purchased a "Koi". None of this has ever happened before introducing it to the tank. Could the Koi have something to do with this? <It sounds like you have a problem with excess nutrients in your water, overstocking, maybe overfeeding, all of which can contribute to algae problems. Take a sample of your water to the fish store and have them test it for ammonia, nitrite, and nitrate levels, and if you can, get your phosphate level checked, too. Koi grow way too big for the average home aquarium, I would take this fish back to the store. Please also see the following links on algae control in freshwater systems. Best Regards, Gage http://wetwebmedia.com/FWSubWebIndex/fwalgcontrol.htm http://wetwebmedia.com/FWSubWebIndex/fwalgaefaqs.htm> My darling goldfish 2/9/06 Hi! I've searched your site for the information I need. I'm pretty sure it's there somewhere, I just didn't come across it. Hopefully this will be pretty easy and painless. My fish, Schroder, has been a little ill as of late. Now I know it's due to a pH problem (I got the water tested) and have been very slowly treating it back up. It's been a couple days since I started very carefully adding a pH decreaser. Here are my "stats": Ammonia: 0 out of .25 Nitrite: 0 out of.5 Nitrate: 10 out of 40 pH: above 8.4 (I know, scary...) Alkalinity: above 300... I was told that this would decrease as I fixed the pH Hardness: 250 out of 300 Chlorine and Chloramine: 0 Salinity: .3 out of .3 (I know... I need to slow down with that, <?> just trying to reduce as much stress as possible and heard this was one of the ways) He's stopped darting over all, though his eyes are kinda cloudy. At the moment, though he seems to be feeling better already, he is staying pretty still and when he does, his back fins are hanging down real low. He also hasn't been eating for 3-4 days and I'm worried about that mostly. I know his spirit will pick up once the pH is down, but what should I do in the mean time? I've tried peas, baby shrimp, his regular food, but nothing. He's still trying to poop, it looks like, but it doesn't look healthy. Thank you for any help you can give. :) Lyz <Do adjust pH by changing new water outside of the system, and slowly drip/add this to the system... and reduce the amount of salt present through these change-outs. Bob Fenner> Goldfish With High Nitrates 3/24/06 Hi Bob Fenner, < Chuck, this time.> I have two goldfish (one's a common goldfish and other is a comet) in a 40 gallon tank. I've had them since early 2003 and they are both a fairly good size (say 7 plus inches. My concern is that my nitrate levels are sky high and I can't seem to get them down regardless of doing frequent water changes, adding buffers as directed, reducing food amounts, and just regular tank maintenance. I'm now changing 10% of the water weekly and changing the carbon filter every 4-5 days. The common goldfish now demonstrates this floating behavior. When he rests and is not actively swimming he floats with his fin up. He was flipping right over but he seems to do it less now but is still imbalanced. This has been going on for just over three weeks now. Some days he seems to get better. The folks at the pet shop said I should feed them sinking pellets so that way they don't swallow too much air and get it trapped in their bellies. I'm wondering if this is really the case since I haven't seen anything to that effect on the website FAQs section. Can you help me sort out what is really happening in the tank? < The high nitrates have stressed you goldfish and they may be starting to get an internal bacterial infection. A big feeding of floating pellets could cause this condition too, but I think it would go away after awhile. Start by doing a 50% water change, vacuum the gravel and clean the filter. Check the nitrates in your tap water. Agricultural areas tend to have high nitrates in the ground water from years of crop fertilization. Feed once a day and only enough food so that all of it is gone in two minutes. If they don't improve after a couple of days then treat them with Metronidazole. I read about introducing plants into the aquarium but the two fish are rather aggressive with plants and won't let them grow. Is this another symptom? Please advise. Thanks, Christine < Goldfish are not really aggressive but rather hungry and continually nibble and tear plants up.-Chuck>
Ryukin Concern - 1/6/06 Last Wednesday, I bought a Ryukin and he is pretty small. For the first day he didn't really eat anything, only because I think he was just getting a feel for his new home instead of the pet store. <Typical.> He began eating a little of his sinking pellets (which I soaked in water for about 5 min.s. before feeding him) and I feed him twice a day: 7am and 8pm. Yesterday morning he did not eat any of his food, he just let it float right past him, however he ate his food that night. And today, he did not eat his food and I am getting ready to feed him again tonight. If he doesn't eat tonight that would mean he hasn't eaten anything today. Is there something wrong with him? <Mm, not enough info yet to go off....> Could he possibly be constipated? Because I don't believe he's gone to the bathroom at all since I got him last week. (Well I think I saw him trying to use the bathroom yesterday). <Possible, but again, not enough info yet....> And the pet store gave me this sheet saying it's ok to not feed your fish for a couple of days-I'm thinking that he may be on the same feeding schedule like he was on at the pet store-maybe he thinks he doesn't have to eat for an entire day or two? (because the pet store clearly does not feed their goldfish daily judging by their "fact" sheet) <Mm, they can go several days, if they must - but most any goldfish will go for food any time they see it.> I am going to feed him some spinach tonight. <A good choice for food. You've read here? http://www.wetwebmedia.com/FWSubWebIndex/gldfshmalnut.htm .> And he does not have dropsy or bad bloating because he is not floating at the surface of the water or anything like that-he swims fine. <Ah, good. Start with a good diet now and you'll hopefully not have such problems.> Do you have any suggestions? Thank you! P.S. The water condition is also fine, except the ammonia level is at .25, it was at 0 when I set up the tank last week. <This needs to be brought to zero. Ammonia is toxic to fish.> But I was told that it's at that level because it is undergoing the biological filtration cycle. <Fish should not be present during the cycling of the tank. Please try to locate some Bio-Spira to aid you in this, and do water changes to keep ammonia and nitrite at zero.> I used Stress Zyme to establish the cycle which apparently takes 4-6 weeks to make things normal. Should I change some of the water anyway? <Yes.> JaMeka <Wishing you well, -Sabrina> Ryukin Concern (Sabrina's go) 1/10/06 I bought some AmQuel Plus (removes ammonia, nitrate, nitrite, and chlorine) last week to get rid of the ammonia level and it is almost at zero now (it surged up to 1.0 last week, now it's slightly below .25, almost a zero by the end of the week). <Water changes are more important.... AmQuel is not a substitute for changing water.> Someone at the petstore told me not to change some of the water right now because the fish could go into shock <Someone at the petstore isn't exactly right, here.... Adding something does not take something away. The Amquel is just changing the ammonia into a less toxic state. It will also potentially postpone your cycle more than just water changes.> and it would ruin the biological cycle that is trying to be established. <Prolong it, perhaps - but that's much better than dead fish.> They also told me to use the Stress Zyme every day to speed up the cycle since my goldfish is in the tank. <Mm, I would just urge you to follow the instructions on the bottle, and rely on water changes to keep the fish safe. Monitor those ammonia levels and do water changes to keep ammonia and nitrite as close to zero as possible while the tank cycles.> I didn't know that they weren't supposed to be in the tank while it is cycling-is my fish going to get sick? <Not if you can keep ammonia and nitrite very, very low.> The pet store also told me not to put my fish in another tank until the cycle is established because putting him in another environment would make him sick. <Mm, not accurate, really; moving a fish from a toxic environment to a healthy environment is usually a good thing. There are certain things to be mindful of (pH, temperature) when moving a fish from tank to tank, but as long as water parameters are similar, all should be well.> By the way he has been eating now, I think he was stressed out because the ammonia level was high at the time I emailed you. <I imagine so! He's probably feeling MUCH better now.> After every feeding, I clean out what he doesn't eat so it wouldn't cloud the tank and raise the ammonia level again. I've had the tank going for 2 weeks now, when can I do a partial water change? <As often as necessary to keep ammonia down.> Should I wait until after the 4-6 weeks of the cycle establishment? <Since fish are present, no, I would advise not to wait.> I also noticed that the nitrate level is still in the safe zone but it is almost a .5-.10 not zero anymore, is that bad? <As long as nitrate does not exceed 20ppm roughly, you'll be fine. Nitrate is not toxic in small quantities. It will increase slowly as your cycle completes.> Maybe the AmQuel will lower it. The nitrite is still at zero, thank goodness! <It will increase as ammonia stabilizes. Just keep up with it with water changes.> Well thanks for the response! <You bet.> JaMeka <Wishing you well, -Sabrina> Ryukin Concern (Bob's go) 1/10/06 I bought some AmQuel Plus (removes ammonia, nitrate, nitrite, and chlorine) last week to get rid of the ammonia level and it is almost at zero now (it surged up to 1.0 last week, now it's slightly below .25, almost a zero by the end of the week). Someone at the petstore told me not to change some of the water right now because the fish could go into shock and it would ruin the biological cycle that is trying to be established. <Yes, advice I agree with> They also told me to use the Stress Zyme every day to speed up the cycle since my goldfish is in the tank. <Mmm, well... won't "speed up"... I would not add more unless the ammonia and/or nitrite exceed 1.0 ppm> I didn't know that they weren't suppose to be in the tank while it is cycling-is my fish going to get sick? <Are already stressed by the exposure, yes> The pet store also told me not to put my fish in another tank until the cycle is established because putting him in another environment would make him sick. <Yes, more stressful> By the way he has been eating now, I think he was stressed out because the ammonia level was high at the time I emailed you. <Likely so> After every feeding, I clean out what he doesn't eat so it wouldn't cloud the tank and raise the ammonia level again. I've had the tank going for 2 weeks now, when can I do a partial water change? <I would hold off till the system is cycled completely> Should I wait until after the 4-6 weeks of the cycle establishment? <Yes> I also noticed that the nitrate level is still in the safe zone but it is almost a .5-.10 not zero anymore, is that bad? <Nope... good> Maybe the AmQuel will lower it. The nitrite is still at zero, thank goodness! Well thanks for the response! JaMeka <Take your time here... feed carefully, don't change much... hold off on the chemical additions... all will be fine. Bob Fenner> Cloudy Tank with Problems I have had a 72 gal tank now for three yrs. What I have in my tank is #3- 3in. Ranchu Goldfish. We had 4. Recently lost a 6 in Pearlscale the size of a peach. You guys gratefully helped me early on when it was discovered I was keeping the tank too clean! Since then alls been well. I do not overfeed, have kept the lights on only in the eve when we are home and still, change 1/4 -1/2 water every weekend, HAD a nice carpet of green algae on the back and sides. One Eheim 2 for biological and don't mess w/it. Also one Fluval that is changed (and not rinsed w/tap) every 2 weeks, also vac. All was well for a few years. Now, all winter the water is cloudy and green. Lost a Pearlscale as I mentioned. Hung around at the top and went belly up. The rest for now are active (and funny) and eating well. I was advised my gravel had bad gasses under it and I wasn't cleaning enough (sigh). Had to change the gravel. I changed the gravel. Cleaned the hoses (again) and did not change the Fluval until the next 2 weeks. STILL I have green cloudy water. Oh, forgot to mention I also took off all the algae on glass as some brown specks were on there as well. The water parameters seem fine as I purchased even new kits just for sure. Using "7.0" conditioner/ph lock as the fellow advised me. I used to use Prime. I just can't seem to get a handle on it and as sad as I am to give up my Ranchu's I adore, I'm ready to give in and give up. We have no room to install an ultraviolet light to system. I have researched all the articles, just kinda lost. Thanks for any help. Kind regards...Robyn < Water parameters should be as follows: ammonia-zero, nitrites-zero, nitrates < 25ppm. Temp 70 degrees F. If all these are fine then maybe the new gravel was not well washed and silts and clays are leaching into the water. The pH should be around 7. If all else is good then maybe a change in diet is needed.-Chuck> Cloudy Tank II Thank You Chuck. I appreciate the advise. Ph=7.0 Nitrite=0 Nitrate=0 (?) Seems like that can't be Ammonia=0 Truly I rinsed and rinsed and rinsed again the gravel in small amounts. Took me all day project :) They eat good food... Sho gold & Pro gold, sometimes some blanched Swiss Chard, taken out after an hour (Stalk really), occasionally algae & Spirulina pellets. Except for Chard, they are fed a piece at a time, a few each, not "dumped" in. Looks like my new Nitrate kit isn't right. Thanks Again. Regards...Robyn <Sounds like you are doing everything right. If you have lots of algae then you might not have any nitrates but it is highly unlikely. Look for a nitrate kit that uses dry reagents. They don't break down as much over time.-Chuck> Cloudy Tank III Thank You Much Chuck. I also ordered a UV sterilizer that I'm told I can duct tape to my filter and hopefully that will solve a good part , if not all of the problem. Will look for that right kind of kit as you suggested. Again, Thanks an awful lot :-)Regards...Robyn < The UV sterilizer will eliminate any free swimming organism and algae. I would be surprised if this helps. Take a clear drinking glass and fill it up with aquarium water and let it sit for a couple of days in a quite cool spot and see what happens. If the cloudy material settles out then it could be a rock or substrate that is breaking down and dissolving in the water. Then it is just a matter of finding out which rock.-Chuck> High Nitrites with Goldfish okay sorry to bother you again. < No problem, that is why we are here.> I just did a 25% water change and did a water test. The ph was neutral and has borderline soft and hard water but however my nitrite is pretty high. My fish still on the floor and not eating and swimming as much. I added salt as recommended. How would I do to help bubba and lower my nitrites. < Clean the tank. Vacuum the gravel to remove the waste that has accumulated there and clean the filter. Feed only once a day and only enough food so that all of it is gone in two minutes. Remove uneaten food after two minutes. If Bubba is not eating he may have an internal bacterial infection and need treating with Metronidazole.-Chuck> Goldfish Acts Strange After Water Change Bubba my black Oranda needs your help. After I changed the water and added all the additives to the water. Bubba stays in the corner has not swam out in about 1 day. What has happened to him? Do you know what happened? <A good water conditioner would handle any chlorine and chloramines. "All the additives" has me concerned. Without knowing what you did or what you were trying to do it makes it hard to comment.-Chuck> Got Air? I saw your website re: goldfish and have a question. Two weeks ago I had 5 goldfish - I had had them for 3-4 months (1 big one for a year). He/? was the first to die. two days later a younger one was floating on top of the water (dead of course); about two days later, another. Obviously I only have two left. The only abnormal thing I am noticing about these two is that they appear to be gasping for air (at the surface of the water)...? WE have several small plants in the pond along with the 'fountain' - Any thoughts? We have been trying to keep the water cool and at a consistent temp. thanks at least for listening. Help if you can. Jayne white < A couple of things could be going on. Check the ammonia, nitrites and nitrates. Ammonia and nitrites should be zero. Nitrates should be under 25 ppm. If any of these numbers are excessive then it could be burning the fishes gills and hamper their ability to get any oxygen. The remedy would be to clean the filters and change some water. Too much food or waste would have this effect. Warmer water temps mean the water has less capability to absorb oxygen so you may need to increase aeration.-Chuck> About using dead coral in gold fish tank I am not new to having and raising goldfish. My niece gave me some dead coral from another tank (not sure if it was a saltwater tank). If it is rinsed in freshwater and set outside to dry will it be safe to use in the tank? I don't want to do anything to mess my tank up. Thank you for any help you can give me. < The coral will dissolve in your freshwater tank creating a higher pH and hardness. The roughness of the coral may create an abrasion hazard if your fish ever rubs up against.-Chuck> Tammy High pH Hi guys, I have a goldfish in a 25L tank, by herself and with a carbon filter + sponge set-up that actively aerates her tank. A few weeks ago, I noticed she had white streaks through her tail fins which were fraying, and there was a white rim at the water surface on the tank. I took a sample of her water to the pet store who tested it and found that while ammonia levels are 0, the pH was around 7.6. I bought a kit with "pH DOWN" (which I think is a salt of Hydrochloric acid), and have since been doing weekly 25% water changes with neutral H2O, since my untreated tap water was definitely alkaline. Simultaneously I treated the tank with "Bactonex" which contains Malachite Green, and her tail healed well. However, a few days ago, I noticed that the streaks & fraying had returned. She tends to hide a bit, which is odd behaviour - she's normally very friendly. I checked her tank water, and found that the pH was in fact much higher than that of the untreated tap water! (I'd estimate tank pH at around 8.0 - it was off the colour scale in my kit). I notice on your site you mention a water conditioner TetraAqua as a culprit, but unfortunately, I don't have the ingredients in the conditioner I use to compare them. In her tank the gravel is white in colour, and appears quartz-like. There was definitely a powdery residue when I washed it before setting up the tank, but I thought I had removed it all. I will check the gravel today by putting it in some distilled H2O & checking the pH. There is also one live plant, and 3 small plastic plants. The live plant is so-so; it's certainly not as lush as when it came from the pet store, but it isn't dead yet. I also tend to get a little algal growth too. My questions are as follows: 1. Do you have any suggestions for culprits? And is there a "checklist" of factors I can follow if this problem crops up again? < Check the rocks and sand/gravel for calcium leaching from the them. The glass of distilled water with some rocks and sand is a good idea. The pH should not change. If is does than switch them for something else.> 2. What would you recommend (some sort of additive or substrate perhaps) to lower the pH and keep it stable? < Any inert medium sized gravel that is smooth and not rough to the touch.> 2. What sort of gravel would you recommend? < Stay away fro coral sands and dolomite. For growing plants there is nothing better than Fluorite by Seachem.> 3. What sort of water conditioner would you recommend, and are there any active ingredients I should look for? <Amquel by Kordon is great for water supplies with chlorine and chloramine. Biocoat by Marineland is very good when adding new fish that are stressed during shipping.> 4. How soon should I start dosing my fish if I see her tail fraying? I'm worried about bacterial resistance. < Fish do not like rapid changes in pH. Get the pH stabilized outside the aquarium. Clean the filter every two weeks. On the weeks that you don't change the filter do a 30% water change by vacuuming the crud out of the gravel. Go to Marineland .com and look under the Dr. Tim's library for articles on water chemistry that will give you a better understanding on the best way to lower the pH. Treat with Nitrofuranace and follow the directions completely on the package. Don't over feed. Feed your fish a high quality food to keep the fishes resistance to disease up.-Chuck> Thanks very much for your help. Che pH Swings Dear Don: I am at my wits' end with my tank and you were such a huge help to me before I thought I'd try one last time to see what on earth I'm doing wrong. To refresh, I have a 10-gallon freshwater tank with 1 Oranda, 1 calico goldie and 1 Pleco. Major new tank syndrome which you advised me to do daily water changes until tank was established. Things improved until Oranda got white body slime on her so I contacted WWM again - advised to continue water changes, wean from ammonia pillow and medicate in qt tank if necessary, which was not necessary as Oranda improved. However, she seemed to "shrink" - she was somehow smaller and skinnier overnight. My whole family noticed it. But she was eating well and had lots of energy and very friendly. Ammonia pillow was removed and levels did not change for the worse. Then my filter motor went kaput Nov. 30. Had not changed filter yet as I'm still trying to establish tank and was advised not to until levels were better. Old filter was gunked out with slime and was disposed of; new filter was installed - have done almost daily water tests but started again with daily/every other day water changes as seemed necessary due to increased levels of nitrate and ph. I have not changed more than 50% at a time and last 2 changes only 25%. Nitrite level remains at 0. Have added up to 1 heaping tablespoon of salt each water change depending on amount of new water. My Pleco up and died 12/5. No signs of problems before, just dead in the tank that morning. Water test that day: nitrite 0; nitrate 20; Alk 120; ph 7.8; ammo .25. Ammonia level has remained at .25 forever - my water is well water - even RO water is .25. Aging water does not lower level. Did 50% water change. 12/6 got new Pleco; rocks and plants (plastic) are slimy; water is clear; new Pleco is sucking on everything and his digestive system works QUITE well if you know what I mean. He's just a tad smaller than my original. Have not noticed any waste from either Oranda or goldie but goldie is growing like mad and noticeably healthy so I know it's happening even though I don't see it, so really not sure about Oranda either. 12/7 Oranda not eating and not moving right front flipper fin. I'm thinking she rubbed up against a rock maybe? and hurt herself so she's not hungry? Is it possible for a fish NOT to be hungry? No visible signs of problems on fin. Tested water: nitrate 20-40; nitrite 0; Alk 120; ph 7.2; ammo .25. Did small vacuuming/25% water change. 12/8 Oranda eating flakes and peas; hangs out at top of water in corner of tank and barely swims so not sure of condition of fin; water test nitrate 20-40; nitrite 0; Alk 120; ph 7.2; ammo .25. Did small vacuuming/25% w/c. 12/9 Oranda not eating; refusing peas which she loves; still hanging at top corner of tank, no swimming; water test nitrate 20; nitrite 0; Alk 120; ph 7.8; ammo .25. ph has climbed again but nitrate has lowered. At this point I just don't know what to do. I'm afraid I'm doing too many water changes but still have not established tank. Don't know how to get the ammonia out of the water but have been advised not to use bottled water. How do you establish if you keep changing the water? How long should all this take? How do you keep your tank established when you replace filters? Should there be a bunch of green slime where the water empties out of the filter into the tank? I don't have that but I've seen it elsewhere. Any idea why my Oranda is getting smaller instead of bigger even when she eats? or why she's at the top of the water only? or why she has no energy? Even when I vacuum the tank there's still a bunch of gunk and debris in the gravel afterwards but unless I do a huge water change I can't get all of it. How do you do that, or should you? Am I supposed to be washing this stuff off? Because if so how do you get established? I am unemployed and can't afford the more expensive aquarium or test equipment. I feel like everything I'm doing is prohibiting development of fish and tank but when I don't, fish either get sick or die. After 3 months, shouldn't I be farther along than this? I'm trying not to get too discouraged, but... Any advice you can give is certainly appreciated. Thanks very much for your time and your help. Robin <Hi Robin, Don again. I see two problems. Your pH is jumping all over the place. Not good. One of the signs of pH shock is excess body slime and white patches on skin. Check the pH of your tap water and the tank. If they are off by more than 2 or 3 tenths do smaller water changes more often. If they are very close together increase to 50% to control water quality until your filter is established. For help with that please read here: http://www.marineland.com/articles/1firstthirty.asp Doing water changes will slow, but not stop, the process. but you need to do them to save the fish in there now. The other problem is replacing the filter. I forget what type you have, but the idea here is to establish that bacteria. Replacing the filter starts the process all over again. If your filter has some sort of "Bio Media" that is what you should NOT clean. The charcoal and floss can be replaced. If this is a sponge filter, either leave it alone or rinse it out slightly with old tank water. Never tap. It usually takes about four to six weeks to cycle. And if you are getting a reading of .25 on every thing you test, the problem is the test. R/O water will read zero. Why your fish seemed to get smaller is a puzzle. Thinner I can understand, but not shorter. Did he loose some tail?> Cloudy Goldfish Tank I have a set up of coldwater goldfish but really struggle to keep the water clean. It seems to get cloudy very quickly and I am not to sure whether this is due to the fish being fed too much, the filter not working correctly or anything else. I have heard of algae eaters but I am not sure what this involves. Your speedy reply would be appreciated. Phil <Cloudy water is a sign of too many nutrients in the water. A bacterial bloom like this is normal in a new setup. No action is needed, except for the normal water changes. In an established system overfeeding is the primary cause. Failing to remove waste and uneaten food with a gravel vac will also cloud up the water. If you clean up the gravel while doing a large water change and stop feeding for 2 or 3 days it will starve out and the water will clear. Then limit food and increase water changes to maintain it. Don> Messing with pH Help! I have a small tank (6 gallons) with two tiny calico goldfish. I checked the pH and it was low, so I put in some powdered stuff they recommended at the pet shop according to the directions. One of the fish died within two days, now the other one has been lying on his side for the last day and appears to be dying. To top it all off, the pH hasn't come up at all into normal range. I feel terrible for my sick goldfish, I need help right away. I want to change the water, but I don't know if this would be worse. By the way, I have another larger orange goldfish who hasn't seemed to be affected by any of this at all, he looks fine. <Do change the water. About 50%. Do this daily for a week or so. Do not worry about your pH reading. It's not an "incorrect" pH that is harmful in most cases. It's the change in pH that kills. Goldfish can adapt to a wide range. A steady pH is the best pH. Also, this is far too small a tank for goldfish. Your problem may not be pH related but poor water quality in general. Test for ammonia, nitrite and nitrate. Keep the first two at zero, nitrates below 20ppm. Either way, water changes are the answer. Don> Hard Water and Goldfish I have a 40 gallon tank with goldfish. The water, when tested, is VERY hard. Is this a concern? If so, what can or should I do to correct it. Your comments are appreciated. Charlie <Not a problem. Goldfish can thrive in a wide range of conditions. You could mix in 50% distilled water, but I see no need to do so for your goldies. Don> Cloudy FW/Goldfish tank Hello, I have a question regarding tank cloudiness. I did read your info but I don't seem to have those problems. I have a 30 gallon freshwater tank with 2 Ryukins in it. I have a 0 reading for ammonia and nitrites and a 7.4 ph reading. <So far, so good> the fish are doing very well and the cloudiness is relatively new (they've been in this tank for about 2 months-cloudiness began about 2 weeks ago). <Right about time for this... due to cycling issues> I have been doing weekly 20% weekly water changes. I have a 10 gal. tank with same readings but it is crystal clear. I have tried the chemical cloudiness reducers but they make no difference. what am I doing wrong? <Mmm, not telling me/us enough for one... what sort of filtration do you have? What sort/s of foods do you offer? Do you have any live plant material? Think these over, and don't panic... if you don't have detectible ammonia nor nitrite, your system will clear of its own accord, and likely soon. Bob Fenner> thanks for the great site, Jill Algae Problem Hi, I've had my one goldfish for about two years now that I won from a school fair. I don't really know too much about goldfish though and what other types of fish they get along with. However, I have what I believe is algae (mostly green and some brown) growing on the sides of the 10 gallon tank and on the aquarium ornaments even after a few days from when I changed the water . I was wondering if I should get an algae eater and if so what type would maybe cause the least stress to my goldfish. Or if an algae eater is not the best solution what other options do I have in order to keep the algae growth to a minimum. Thanks in advance. Liz. <Hi Liz. Goldfish are best kept with other goldfish, I have seen people keep a Plecostomus with their goldfish, but would not recommend it. If I were you I would just use an algae scrubber pad to scrub off the algae before water changes. Best Regards, Gage> -Tetra Freshwater Additives- Hi everybody, I started out with a fish bowl with two goldfish in it, as a present from my girl friend. Next day I was at the book store looking for a book on goldfish. The day after the small bowl was changed with a 2 gallon bowl (it had to be a bowl to preserve the original present :). I slipped in a small filter and started doing 50% water changes every three days. Next, I added some Tetra Nitrate Minus, thinking it would help me keep the nitrate level low. <Hmmm...> MISTAKE. Too little water, too much bioload. As it says on the package, using Nitrate Minus with high levels of nitrate did increase the KH to 15dH pH to 8.5+. The little guys were doing fine, but I owed them a proper tank. So, I bought an 18 gallon tank, transferred the substrate (with the Nitrate Minus mixed in it), the filter and the little guys into their new home. It's been three weeks and I have 0 ammonia, 0 nitrite and less than 5ppm nitrate. <I wouldn't get so hung up in nitrate, it's the least toxic of the three. You need to be concerned with ammonia, nitrite, and pH. The nitrate level makes little difference.> This time the KH is stable at 5dH but the pH has gone up to around 8.3 from first fill measurement of 7.2. The package says that the product has a stabilizing effect on pH and KH. What do you think about this product, it looks like I don't need to make any water changes yet, but it somehow doesn't feel right. <I would suggest a 25% water change every two weeks for these critters with a gravel vacuum.> Should I do water changes to try to bring pH down slowly. <I would stop using the Nitrate Minus, and as the pH goes back down to around neutral, pick up some Seachem Neutral Regulator to keep the pH buffered at 7 if needed.> With KH being around 5dH, I'm afraid to have a sudden pH crash. The fishes seems to be doing fine. Should I change anything? <Like I said, once the pH drops back down (with goldfish this should happen on it's own) use some Neutral Reg.> Tetra also has another product called Easy Balance, which is supposed to decrease the water changes to %50 every six months. Sounds too good to be true. Still you'd have to remove the solid waste from the tank bottom somehow I guess. <They can come out with any magic juice and make any claim they want but you'll be hard pressed to surpass the effectiveness of a good water change with a gravel vac. I would save your money!> So, do you have any ideas about these products? Are they any good, or needed? <In short, you don't need either. Frequent partial water changes with a gravel vacuum combined with conservative feedings are all you'll need to keep these guys happy. Good luck! -Kevin> Thanks, Husnu Shrinking fish In my 20 gal tank are two 2 inch Goldfish, two 2.5inch Goldfish and one 5-6 inch Shubunkin (measured including tails). I've had them for 2 months and I feed them 2x/d, knowing that "most goldfish problems are from overfeeding". I also don't want to cloud my water too much because I probably clean the AquaClear 300 every 3 wks and change 1/3 or 1/4 water every 2-3wks. Problem: I think my fish are smaller or rather skinner! Is that possible? Or am I just used to seeing these fish now and don't think they are sooo big anymore compared to when I first got them. >>Hello. I recommend you buy yourself some test kits. Ammonia, nitrite, AND nitrate. Test them all, and test regularly. You should always have zero ammonia and zero nitrites. But the nitrAte test kit will tell you how often to change your tank water. Try to keep the nitrAte level in a safe range, say around 40ppm. I believe you are not changing your water often enough. With the amount of fish you have in such a small tank, you really should be changing around 50% of your water per week! Your fish will become stressed if the nitrate level gets too high, and they will also become stunted and stop growing, which can lead to disease and possible death. Please buy some test kits! -Gwen<< Saltwater Goldfish?! - 02/10/2004 Hello <Hi.> I have one 9 year old 5" goldfish in a 10 gallon tank with a little gravel on the bottom. The temperature is normally kept at 73 degrees. It has a Penguin BioWheel mini power filter Flow: 100 GPH. There is also an aerator pump in his tank. I change 30% water once a week to which I add 5ml (1 capful) of "Cycle" and use "AquaPlus" to dechlorinate water. He eats approx. 12 Wardley pellets a day. <So far, so good....> 3 weeks ago while I was gone he was overfed. I had just done a 1/3 water change and came home 3 days later to a smelly, dirty tank. Fish was sitting in the corner but swam around when disturbed. Still eating good. Thought he might be doing "flashing" motions across the tank once in awhile. <Likely the "flashing" is a reaction to irritation (ammonia, nitrite) in the water.> I tested his water: there was a bit of ammonia and nitrites in the water and the nitrate reading was high. <Bingo.> I did a 25% water change and siphoned a lot of waste from the bottom. Changed the charcoal filter and added a capful of "Cycle". Did not feed fish anymore this day. <Larger water changes may be more appropriate while the water levels are off....> The next day the water was clearer and all reading were a little lower. pH 7.5. I did a 20% water change. Not so much waste at the bottom. Fed as usual. <Okay> I tested the water the 3rd day, pH was the same and all other reading were almost normal. But noticed red streaks on tail fin. <"Almost" normal - I assume that means some ammonia, some nitrite? Elevated nitrate? This must be rectified with water changes.> 4th day - ph same, ammonia close to 0, nitrites less than 0.3, nitrates medium 5th day - all readings the same, except nitrate level less? 6th day - all readings the same except nitrate levels rising 7th day - ammonia 1 (touch higher), nitrites 0.2 (touch higher), nitrates 7 (higher) Did 25% water change (6 days since last water change) Noticed foam on top of water surface after I had changed the water? Maybe from aerator? Ammonia or bad bacteria in tank? <Something does seem "off" here.... What kind of test kit(s) are you using? And again, if you are reading any ammonia and/or nitrite, water changes are crucial.... must keep these at zero.> Tested water 3 days later to find ammonia close to 0, nitrites 0.1 and nitrates 6 Tested water 2 days later to find ammonia perfect, nitrite 0.1, nitrites 7-8, pH 7.5 Did 25% water change (6 days since last water change) <Sounds like the tank is cycling.... perhaps to account for the accumulated waste from overfeeding, and the resultant increased waste output of the fish.> Feb 1 5 days later fish water was cloudy, sticky and the fish lost two pieces of his tail fin. <Yeowch> Why did his water get so bad? His tail fin seems to have white mucky stuff around it? I don't think its ICK. <No, doesn't sound like ich at all. Sounds like bacterial fin rot, brought on by the poor water quality....> His fins have been red for 2 weeks now and have gotten redder each day. All his fins now have red streaks on them. He's still eating well, but sitting at the bottom of his tank most of the time unless disturbed. <Water changes.... and perhaps an antibacterial medicine, if proper water quality does not improve his fin erosion.> Changed 80% of his water and put in a new charcoal filter <Ah, good.> Added 2 tsps. of salt to the water and another 2 tsps. 12 hours later. <Perfect, this should help.> Fish seemed better with salt. Swimming around more. Eating well. Think he's still "flashing" once in awhile. <Probably still a reaction from the water quality.... keep testing, correcting when necessary.> Feb 2 He seemed to do well with this addition of salt but I wasn't sure of the dosage so I called an aquarium place in the city. <.... One to two tablespoons per ten gallons, possibly slightly more for a goldfish, but not by a lot....> He told me to change 1/3rd of the water (which I had already done yesterday) and to add 7 Tablespoons of salt (less the 4 teaspoons I had already added) <Oh. My. Goodness! That is a LOT of salt.... FAR more than I would be comfortable recommending....> and raise the temperature to 80 degrees. <If the goldfish is dealing with a bacterial infection, this is not a great idea.... For one, bacteria multiply at a greater rate in higher temperatures, and for two, goldfish do not do well in such high temps.> Then in 3 days, change another 1/3rd of the water and add another 7 Tablespoons of salt. <WOW. Okay, so we've got 2/3 of the original 7 tablespoons in there after the water change.... that's 4.67 tablespoons.... PLUS the new 7 tablespoons - up to 11.67 tablespoons....> He said to continue this every 3 days for 2 weeks. Thought this was too much salt, so I asked him to repeat this process and he affirmed it. <Holy wow. So, just to appease my curiosity, figuring this: we have 11.67 in the water now. Take away a third of it (water change), we have 7.78 tablespoons, plus the new seven, up to 14.78T.... Three days later, now 16.85T.... Finally ending at 18.23T in a 10 gallon tank - if I'm figuring correctly, that's nearly one fifth the salinity of marine water....Yikes! Far, FAR too brackish for a goldfish....> So I did this! Of course dissolving it in a cup with some of the tank water first. Pouring it in very slowly and not directly on fish. By the way, I'm using a pure sea salt. <Which will *dramatically* affect pH, making it far too high for this animal, especially in the state he's in. This would wipe out the bacteria, without a doubt, but cause many problems to the fish in and of itself.... more harm than it's worth.> Feb 4 Changed 1/3 water and added 7 Tablespoons of salt. Fins a little less red. Feb 7 Tested water - pH 8, ammonia 0.1, Nitrites 0.2, Nitrates 6, General Hardness 120ppm, Carbonate Hardness 60ppm. <The high salinity is probably starting to kill off your nitrifying bacteria, at this point, hence the ammonia and nitrite refusing to settle; water changes, with no salt, are in order....> Changed 1/3 water and added 6 Tablespoons of salt. Only has redness on tail fin now, but it still seems to have whitish stuff (not ick) around the edges of tail fin. <Likely the bacteria causing his fin rot have started to die, along with your biological filtration.> So I'm supposed to do 3 more water changes and add another 21 Tablespoons of salt over the next 8 days. I'm scared about using this much salt!! <I would be, too! I'm glad you're concerned!> Should I do this? <Frankly, in my opinion? No!> He said that if this doesn't work, I could then try "Melafix"? <I do not stake much on the effectiveness of Melafix. It may help, and is worth a shot, but you *must* continue water changes, and be diligent about them, as long as you see any ammonia and/or nitrite on your tests. You may want to consider an antibiotic, like Kanamycin or Nitrofurazone ("Kanacyn", "Furacyn", and "Spectrogram" are some proprietary names).> Do you think this is safe? <The salt? No. The Melafix? Not harmful, may help, might not.> Should I stop the salt? <Yes.> Should I instead be using Melafix or a broad-spectrum antibiotic like furan, Kanamycin sulfate, spectrogram, Nitrofuran-G or Maracyn & Maracyn II? <See now, you've read my mind. I do not like to recommend the Maracyns unless you know *specifically* what bacteria you are treating - Maracyn I (erythromycin) treats *only* gram-positive bacteria, and Maracyn II (Minocycline) treats *only* gram-negative bacteria. I would go with Kanamycin, Nitrofurazone, or a combination of the two; these are my antibiotics of choice.> Or should I wait until salt treatment is over and then use one of these products? <I would slowly (over a few to several days) lower the salt, 'till you've got about 2 tablespoons per 10 gallons, then begin treatment with antibiotics (if necessary). First and foremost are water changes.> I'm not sure if his fins turned red from the bad water quality, <This is, if not the entire problem, at least what started it.> from parasites, <Unlikely, from your descriptions> or he has a bacteria infection. <Quite possible.> Would he have Fin or Tail Rot? <Likely.> He has never lost his appetite!! <A *wonderful* sign! What tough fish there are in the world!> I'm sorry this was such a long letter, but I am concerned about the salt. <Goodness, don't be sorry! The more detailed the description, the better - and *certainly* don't be sorry about being concerned for your fish! That's a good thing.> Hope you can at least lead me in the right direction. <I hope so, too.> Thank you for your time. <Any time - glad to be of service.> Teri Odenthal <Wishing you and your salty goldfish well, -Sabrina> Saltwater Goldfish?! - II - 02/14/2004 Hello <Hello again, Teri!> Thank you so much for responding to my email. <You bet.> I have to admit that this goldfish actually belongs to my friend, and she wanted me to try and help her. She continued to follow the advice given to her my the aquarium guy in the city, but has now realized that this "salt treatment" he recommended is too much!! Anyways, this is a continuation from my last email, ending on February 7th, when I last tested and changed the water for my friend (I do this for her when she's working): Feb 10th My friend, still convinced that this aquarium fellow knew his stuff, changed 1/3 water, added 7 Tbls. salt, (I figure the fish has about 17 Tablespoons in his 10 gallon tank now?) added 1 capful "cycle". and left temperature at 80 degrees. Feb 13th Finally after my friend read your email, she started to worry about adding this much salt. She changed 1/3rd of the water, added 1 capful of "cycle", changed the carbon filter and did not add anymore salt. Or should we add a little to lower the quantity slowly? <I would not add any; just do water changes daily to lower the salinity. If you need to do large water changes, as I suspect you will (nitrifying bacteria may have died off), then figure how much is in the tank now, and add some salt to the water change water, so as not to bring the salinity down too rapidly - don't want to shock the fish.> She is slowly lowering the temperature. It is now at 78 degrees and she will continue to lower it over the next few days until it reaches about 74 degrees. <Even lower is better with goldfish; this is a coldwater fish by nature.> She told me the fishes tail fin had some red on it again, but it was a lot darker colored than before, and that the fish was still swimming quite fast around the tank and settled down in the corner so quietly. <Redness is a sign of irritation from something in the water being inadequate - I suspect ammonia and/or nitrite.> He is still eating good. Was last fed this morning. She said the water looked very clean, but I told her to test the water. <Definitely. Just looking "clean" really gives absolutely *no* insight into water quality.> These tests of course would be after the 1/3rd water change. Ammonia 0-0.1, Nitrites 0.1-0.2, Nitrates 10?. <Again, what sort of test kit(s) are you/she using? If she's reading ammonia and nitrite even *after* a 1/3 water change - yeah, I'm sure the fish is having to endure lots of ammonia and nitrite issues. The tank will re-cycle as you come down in salinity, and may require even daily water changes to keep the fish healthy.> She did not check the pH. I bet its too high though! <With all the sea salt? Likely.> She then added another capful of "cycle" and will check the water again tonight. If it's still off? Should we do another water change so soon and how much? <As much as necessary to keep the ammonia and nitrite down.> Do we add more salt? <If you do large water changes, yes, I would add some salt, so as not to shock the fish by changing the water properties too quickly.> She thought of using Melafix or the antibiotics you mentioned also. Should we try Melafix first <I do not have a high opinion of MelaFix; it is worth a try, if you are interested. It may help. It shouldn't hurt, at least.> and can we use it with salt in the water? <Yes.> Or just go straight to the antibiotics? <If you see a white or milky edge to the eroded fin, I would probably go ahead with a mild antibiotic. I would not do this until you've gotten the salt content to a manageable level, though. This will also give you a handful of days to observe the fish and see if he begins to improve on his own with improved water quality.> I think its scary using antibiotics, no? <Not if used properly. Again, my antibiotics of choice are Nitrofurazone and Kanamycin; the very low dosages of them in Aquatronics' medications (Furacyn, Kanacyn, Spectrogram) provides for a very mild treatment. I have not had any fish react adversely to either.> Thank you for reading this again, <Any time! Truly, glad to be of service.> Teri and my friend with her beloved salty goldfish <Wishing you, your friend, and the salted fish well, -Sabrina> Saltwater Goldfish?! - III - 02/14/2004 Hello Sabrina <Hi, again!> Thank you again for your email and for answering my questions so thoroughly. We are so relived to correspond with you about our "salty goldfish". <Any time, really. So glad to be of service.> Thank goodness for email!! <Indeed! What a valuable resource communication is!> Yes, we figure that salt has played havoc with the biological system because we were already changing 1/3 of the water every 3 days. We didn't have a problem with the water when we used to change it once a week, before the overfeeding episode of course!! <Heh, when it rains, it pours!> Guess he could have a 20 gallon tank. I have not talked to my friend "Karen" yet after she tested the water last night, so I don't know what the readings were, or if she had to change some more water. I did print out your last email to us and left it at her house. I peeked through the window to see the fishy and he seemed to be swimming around normally. <Swimming is always good.> By the way, we are using: A-7820 Hagen Test Kit - Ammonia for Freshwater - 0.0 - 7.3 mg/l- 70 tests A-7825 Hagen Test Kit - Nitrite Test-Fresh and Salt water Nitrite Test- 0.0 - 3.3 mg/l- 75 tests A-7845 Hagen Test Kit - Nitrate-For Fresh and Salt Water- 0.0 - 110.0 mg/l-80 tests A-7815 Hagen Test Kit - pH Wide Range 4.5 - 9.0- for Freshwater and Saltwater- 100 tests A-7830 Hagen Test Kit Carbonate and Total Hardness For Fresh and Salt Water <Sounds good.> From Feb 1 - Feb 10 (gone from 7 up to 17 Tablespoons of salt) Feb 14 - removed about 5 Tablespoons with 1/3 water change. Is losing 5 Tablespoons too shocking for fish? <Mm, possibly, the best way to gauge this is through using a hydrometer.... the SeaTest box-type is the only one that I know of that reads low enough for this purpose (the new Marineland one might, as well). I would not add it back at this point, though, as he's already acclimated to the lower salt level - that's certainly better than going up and down quickly & repeatedly.> So I figure that there is about 12 Tablespoons of salt left in the tank, unless she has changed some more water since. I hope that if she has already done a large 80% or so water change, she will read your email soon and add some salt so the fish is not shocked by the change in salinity. If she has changed close to 80%, that removes 9 1/2 tablespoons of salt? leaving us with 2 1/5 Tablespoons in tank? She should add how much salt? Maybe 4 Tablespoons? <Again, if the fish has had time to acclimate, I would not add any back.> If the water readings are okay, we will continue to change a small amount everyday until about 2 Tablespoons are left. Maybe adding back half of what we take out? <Sounds good.... again, the best way to deal with this is using a hydrometer, so you can better understand how much salt is in there. However, goldfish are such resilient fish, it is likely not necessary to be terribly accurate.> I'd better get off the computer in case she's trying to phone me. Thank you so much!! <Any time.> Teri <Wishing you and all well, -Sabrina> Saltwater Goldfish?! - IV - 02/18/2004 Hello again <Hi, Teri!> Saturday Feb 14, as noted in "salty goldfish part III" we changed 1/3 water and did not add anymore salt. 12 Tablespoons left in tank. Added 2 capfuls of "Cycle" and changed the carbon filter. Tested water after this water change. Ammonia 0-0.1, Nitrite 0.1-0.2, Nitrates 10. Lowering temperature from 80 degrees to eventually 74 degrees or less. <Wonderful. Keep up with the water changes, please try to get ammonia and nitrite to zero. What is the pH looking like?> Sunday Feb 15, the next day , she changed 15% of water and did not add salt. 10.2 Tablespoons still in tank. <Okay> Tuesday Feb 17. I tested the water - temperature at 76 degrees now, pH 8, ammonia 0.1, nitrites close to 0.1, nitrates 5. I suggested she change 30-40% of water, clean the carbon filter and add 1 tablespoon of salt. This would leave 7-8 tablespoons of salt in the tank. <Cool. How big of a tank again?> Wednesday Feb 18 we will test the water again. I want the ammonia and nitrites to read 0, right? <Yes, exactly. And try to keep nitrates less than 20ppm, which you are currently well under.> The fishes red fins looked better on Feb 4th after there were 12 tablespoons of salt in his tank and/or when water quality was finally better after changing 30% every 3 days. <Improvement in water quality is the likelier one, I wager.> They started to turn red again anywhere from or after Feb 7th after there was 14-17 tablespoons of salt in his tank and are still getting quite red again. Otherwise he's eating and acting quite normal. <Sounds good, except for the redness in the fins. With lowering salinity and pH back to normal, and improving water quality, I expect this will subside.> So, I think I've concluded that the salt will help relieve stress from poor water quality only if the water quality is improved first. <Agreed.> It will not help if the water quality is poor, nor will it help keeping a bit of salt in the water to help prevent stress in a fish if the water accidentally gets bad. <Agreed, again. Water quality is of paramount importance.> His fins turned red before we started removing any salt from his tank. I think I'm convinced that too much salt killed the good bacteria and caused bad water quality, but were these readings of ammonia and nitrite enough to redden his fins? <Yes.> Could the large amount of salt itself have caused stress and the return of the red fins? <Yes. Or the heightened pH from the buffers in the marine salt.> He started to look better with the salt treatment before, would you advice leaving some salt in the tank for awhile to see if his red fins heal again after we correct the water quality? <I keep many/most of my freshwater tanks salted at a rate of one to two tablespoons per ten gallons of water. You may wish to use a salt marketed for freshwater use, as this will not influence your pH.> Thank you so much again for reading this!! <Any time, really, glad to help in any way.> Teri, Karen and Salty Goldfish <Wishing you well, -Sabrina> Saltwater Goldfish?! - V - 02/23/2004 Hello Sabrina <Hi again, Teri! Hope all is well.> My girlfriend phoned me Sunday Feb 22. The goldfishes fins are still red and getting worse. The dorsal fin has a red spot on it too. <Drat. What are the water parameters at this time?> Seems we're starting all over again. He's still eating but darts around once in awhile. <Signs of irritation.... could just be the salt and water parameters, could be illness.> We've been changing about 20% of his water every other day. Salt in tank is approximately 6 Tablespoons now. <Forgive me, please refresh my memory - what size tank is it, again?> We are having someone pickup "Melafix" for us today. <Although I am quite skeptical at the effectiveness of this stuff, it is at least not harmful, and does seem to help speed up regeneration of damaged fins.> I'm also having him check on "Aquatronics" A 3 Kanacyn, A9 Nitrofura-G or A10 Furacyn. Do these antibiotics have both Nitrofurazone and Kanamycin in them? <No. Kanacyn is Kanamycin sulfate, Furacyn is just Nitrofurazone, and Nitrofura-G is Furazolidone. As far as I know, Spectrogram is the only Aquatronics med that combines both Nitrofurazone and Kanamycin.> What about other brands if we can't buy "Aquatronics" here? <There are certainly other brands/options. The reason I recommend Aquatronics above others is simply due to their very wide selection of effective products.> You said "Aquatronics" antibiotics provides a mild treatment. <Indeed, they tend to have low (but still effective) dosages.> Nobody around here seems to carry Spectrogram; which I read has both Nitrofurazone & Kanamycin as active ingredients. I could order it through the mail if necessary though. <I do not believe it is utterly necessary to use that particular product.... My next preference would be either Kanacyn or Furacyn> They do all carry "Mardel" Maracyn 1 and Maracyn II, which I read can be used together without damage to the biological filter? <I would rather say little damage to biological bacteria; these are both pretty mild on our nitrifying pals. HOWEVER, I will not recommend using both Maracyn I and II at the same time. It is not the nitrifying bacteria that I would fear for, but the fish. I have tried twice to treat using both of these at the same time, once on a terribly ill fish, and once on a group of not-very-ill fish, and in both instances, the fish reacted horribly to having so much medication in the water, even only several minutes after adding the second med. I will not repeat that procedure, and I will not recommend it to others.> You said you would not use them though. <Mm, yes, true, but don't take that to mean that these aren't good products. The issue with them is that Maracyn I is erythromycin, which is only effective against gram-positive bacteria (that's bacteria that do have a cell wall), and Maracyn II is Minocycline, which is only effective against gram-negative bacteria (that's bacteria that do *not* have a cell wall). I don't like to recommend these unless the person asking is very, very positive of what illness (and therefore, what bacteria) they are dealing with; if the bacteria is misdiagnosed, and the person uses the wrong one, it will be completely ineffective, and the fish is out of luck. I will never recommend using both Maracyn I and Maracyn II at the same time, as above.> I don't think they contain Nitrofurazone & Kanamycin? <Correct, as above.> If we decide to use an antibiotic and I finally understand which one to use, is there any precautions? <Follow the directions, to the letter. When treating, keep in mind that a ten gallon tank with two inches of sand in the bottom is not containing ten gallons of water; try to account for water displaced by decor and substrate. Some medications are safe to overdose (or even double - or triple - dose) and some are safe to use in conjunction with certain others.> What do we do about the biological filter? Do we have to re-cycle the tank again after treatment? <Depends upon what med you use. I would still recommend Spectrogram (Kanamycin & Nitrofurazone); failing that, I would recommend Kanacyn (Kanamycin). There are several other antibiotics available that would be effective as well; these are simply what I have had wonderful results with, especially in treating goldfish. They are also very, very mild on biological filtration.> What about the dissolved oxygen level in the water? Medications "antibiotics" lower the level, right? <If you do not have a test kit for oxygen, you can add an airstone to the tank if you feel it necessary. The goldie would probably enjoy that, as well. Otherwise, do keep an eye on the fish for labored breathing.> Should we have left the temperature closer to 80 degrees if he was not healing? Its at about 76 degrees now. <I would (slowly) drop the temp further; high temps will increase the rate at which bacteria multiply. Plus, with lower temps, there are higher levels of dissolved O2. And on top of that, goldfish prefer cooler water; it might make him feel a bit better.> I know his symptoms were getting better after the salt treatment, water changes, the temperature at 80 degrees and then started to reappear at the highest level of salt, even after same amount of water changes and before we started to lower the temperature. <If it were me, I might seriously consider medicating at this point. I have always had goldfish respond very well to Kanamycin and (although I am skeptical as to its abilities) MelaFix. These can safely be used together. The Aquatronics' dose for Kanamycin in Kanacyn is low enough, you need not make adjustments as to exact volume of water (for example, one whole capsule for one ten gallon tank).> Anyways, I will observe goldfish today and see what his fins look like. You know they never really looked like "fin rot". Does losing pieces of his tail fins, like he did 2 weeks ago, mean he has "fin rot"? <It could be a strong indicator. So far, it does sound possibly like a bacterial issue; I have not seen anything in your emails that would indicate parasitic problems to me. Though the fish may simply be irritated by the water parameters and salt, I think I would medicate. A photograph of the fish's affected fins would be great, if you can provide it.> I should keep my questions to a minimum, heh? <No, not at all! Truly, I am glad to help.... the more I can help, the better. I'm glad you are so eager to know more about your fish. I can recommend some good titles on fish health, if you're interested?> Oh well, the whole picture is getting clearer thanks to you!! Teri <Glad to hear it. Wishing you well, -Sabrina> Saltwater Goldfish?! - VI - 02/28/2004 Hello Sabrina <Hi, Teri!> Me again! <No, not you again! Just kidding. ;) > I want to try to make this as short as possible. <Not necessary.... do feel free to take your time, be as lengthy as necessary.> We have a 10 gallon tank and I have attached "Our Goldfish Daily Record" and pictures of our fish. <Yes, thank you, the pics are immensely helpful. By the way, *excellent* record keeping.> As you can see we have not used "Melafix" or "Antibiotics" yet. <I would do so.... It looks to me that you might be dealing with fin rot, from the pics.> Please excuse our figuring on the salt levels left in tank. We did not buy a tool to measure the salt accurately. Aquatronics products are no longer sold in Canada? <Mm, didn't realize you were in Canada. Or more likely, I did, and I forgot. And again, Aquatronics are certainly not the only product available to use; I usually recommend them as they are usually very available locally in the US, and have a very broad selection. There are certainly other good products out there!> I could order them online. I did purchase an antibiotic though. I have attached a page on this "Seachem" product. <The "Kanaplex", yes? This would be absolutely fine. I didn't realize Seachem sold antibiotics other than Metronidazole.... this is good to know!> As you will see, our water tests are finally great. Not sure about pH though? <A pH of 8.0 can be quite irritating for goldfish. What is the pH from your tapwater (or whatever source water you use for the tank)? Do please start using a salt marketed for freshwater use as you do water changes to replace the saltwater mix. It will lack the buffers of the saltwater mix that is causing your pH to stay high.> We were getting ready to start treatments with Melafix and/or Antibiotics, but now we're more concerned about the scratching, darting. <Quite likely attributable to the high pH. Do keep your eyes open, though, be on the lookout for any other developments, like ich. Again, I think this is a result of the irritation from the high pH. My pond fish show these signs in the summer when our tap water jumps up in pH (from 8.3 in the winter to 9.2(!!) in the summer) if I have not tested the tap and become aware of the pH issue before a water change in the pond.> I will change about 20% water Thursday morning because I there's poop on the bottom and his filter is plugged up again with brownie wastes. Wish me luck! <Good luck!> Karen's not home till Friday and I hope fishy doesn't decide to jump out!! He probably won't. I'm being paranoid!! Its getting a bit frustrating isn't it? <It is always frustrating dealing with sick fish. Don't worry, you're not alone in this.> Thank you for reading and looking at all this. <Any time.> And again thanks for all your help. <One last comment/suggestion: I assume the pics are of fishy's permanent home, yes? It would probably make him feel better and safer if he had a couple spots to hide if he felt necessary. A couple of fake plants and a (new, clean) terracotta flowerpot would make him quite at home. Once you're done helping him get healthy again, I would very strongly recommend getting some greens in his diet; a few pieces of Anacharis/elodea (a water plant that goldfish like to eat) would make him quite happy, I'm sure. Also, shelled peas, blanched veggies like zucchini, cucumber, or spinach would be a good supplement. There are also some good frozen veggie foods, like Ocean Nutrition's "Formula Two", that you can find at the fish store. Keep in mind, these fish are vegetarians by nature, and unfortunately, a diet of only pelleted or flake foods can lead to some health complications, like constipation and bloating. Adding some plant matter into his diet will prevent this (and taste yummy, too).> Teri & Fishy <Do please keep in touch! Wishing you, Fishy, et al well, -Sabrina> Saltwater Goldfish?! - VII - 03/07/2004 Hello Sabrina <Hello, Teri!> Thank you again for your reply on February 28th. <You bet.> My computer was down for a few days, so I couldn't send you a update until now. <No problem.> The last record I sent to you ended on Wednesday Feb. 25 with fish darting around on the bottom of tank off and on. Can't remember if I told you that the red spot on her dorsal fin was gone and that the part of her upper tail fin that fell off a couple of weeks ago is starting to grow back. <Ah, wonderful news, for sure!> Thursday Feb 26 - fish seemed pretty normal this morning. Didn't jump the tank, thank god!! Water readings perfect. pH still at 8. Temperature 76 degrees. Changed 25% water (4 days since last change). I am babysitting her today so I did not spend all day with her but when I checked her this afternoon and this evening, she wasn't doing any darting around. Did notice she was holding her body vertically up with head towards the water return once in a while. She really seemed to like swimming under the new water I was pouring in. <Fish that are having (or recovering from) some sort of irritation will certainly do this. It probably feels good to have the water flowing on and around them, soothes their itchin'.> Friday Feb 27 - Karen was back home and said fish was darting around the tank this evening quite hard. <Uh, please forgive me, I'm having a huge brainfart. I've probably asked this, but as it is an incredibly important issue, I will kick myself if I don't confirm - are you using a dechlorinator when you do water changes? Something that removes both "chlorine" and "chloramine"?> Saturday Feb 28 - fish still darting around once in awhile. Water looking a little cloudy. Water readings still good though pH is hard to read on color chart, but I think its gone down to about 7.9? Sunday Feb 29 - fish still darting around. Not hanging out by water flow now. Water readings - pH the same, ammonia 0.1, nitrites 0.2, nitrates 5. Water cloudier than yesterday. Mostly because of white slimy stuff from her fins. <How are those fins lookin'? Any better?> Did a 30% water change and added weekly dose of "cycle". We're surprised she hasn't hurt herself from her strong darts across the tank! Monday Mar 1 - removed carbon from filter cartridge, added 1 teaspoon of "Melafix" Temperature now at 75 degrees. Tuesday Mar 2 - Karen wasn't comfortable with all the brown mucky stuff on gravel and rocks (which the tank has always gotten for years now) so she decided to take the gravel out (not the fish) and clean it and also cleaned the glass inside. She usually does this once in a while. <Yikes - huge tank cleanings like this will completely wipe out the nitrifying bacteria that we need in our tanks! Siphoning the gravel using a gravel vacuum will remove detritus from the gravel. If the gravel is too large to vacuum, I would recommend (slowly) replacing with a smaller grade gravel. It should never be necessary to completely clean the tank.> She then added 1 Tablespoon of "Freshwater Aquarium Salt" and 2 teaspoons of "Melafix". Figure we didn't have anymore than maybe 1 Tablespoon of "sea salt" left in tank by now. <Sounds great.> Wednesday Mar 3 - fish seems very happy. She's does a few fast swims back and forth sometimes, but no hard darting back and forth! We were very happy!! We are lowering her temperature to 74 over the next 12 hours. <I'm sure those cooler temperatures are feeling good by now!> Will continue to add 1 teaspoon of "Melafix" daily to her tank until Monday (7 days of treatment). Might have to do another water change again before Monday, but we'll just adjust the dosage of "Melafix" somehow. <Exactly. Just compensate for the amount removed in the water change.> Parts of her tail fins are still bright red, so if the good water quality and/or "Melafix" doesn't clear it up, we'll use the Kanaplex antibiotics. <Sounds like a plan. Uh, I'm still curious on the dechlorinator issue....> Thank you for all your advice on the fishies home and diet. We are looking into getting a 20 gallon tank for her, so we can add some more decorations to her home. <Oh, wonderful!!> Terracotta pot is a great idea! Karen used to have a lot more rocks and decorations in this tank, but when the fish got bigger she removed them. She mainly feeds her green pellets but does give her shelled peas and some frozen bloodworms once in awhile. Fishy loves them. Thanks for the other food idea's! <You betcha.> Please let me know what you think or if you have any further suggestions for us and fishy. I'll keep in touch and let you know what's happening. <Please do.> Teri, Karen & Fishy <Wishing you all well, -Sabrina> Saltwater Goldfish?! - VIII & IX - 03/15/2004 Hi Sabrina <Hi again, Terri!> Yes, we do use AquaPlus which claims to take care of any "chlorine" and "chloramine" in the water. <Ah, whew! What great relief.> We've been adding 1 teaspoon of Melafix every day now for 7 days with one water change in-between of 25%. We did leave the filter cartridge in the pump but removed the carbon from the filter for this week, so that the foamy material would still catch any debris from the tank. The pH is still around 8 and ammonia and nitrite have been kept at 0. Nitrates are also low. Figure we have about 2 Tbls of aquarium salt in tank. The temperature is now at 74 degrees. <Yay, better and better.> Her fins are looking better and she's eating well, but yesterday on her 7th day of Melafix treatment, I noticed that about 15 minutes after I added Melafix, she shook or shivered a bit and then did a few darts on the bottom of tank. Didn't notice her doing anything weird after that, but then I am just babysitting again and was only with her again for a half hour this evening to feed her. <It could be that the MelaFix is slightly irritating. I'm not a fan of the stuff, but I've never had any negative effects from it. I don't doubt, though, that the fish might find it irritating.> On the Melafix bottle it says that "Treatment can be continued if necessary" So I will change 25% of water today, March 8th, and add more Melafix, to keep it at 7 teaspoons for maybe another 2 days or so? I'm not sure if they mean to add another teaspoon (increasing the dose each continuing day) or to leave it at 7 teaspoons for the extra days? Any idea how long we should continue Melafix? <Mm, that's pretty much up to you.... I am still very, very skeptical of its claims, but as I said, I've not seen any ill effects from it, either. If you have reason to believe it is irritating your fish, I would discontinue use. If you see what seems to be improvement, and feel like you can attribute that to the MelaFix, well, keep goin'.> Thanks again for keeping in touch and reading all this! Your information has helped us along so much!! <You betcha. And sorry for the delay in this reply.> Teri, Karen & Fishy ------------------- Hello again Sabrina <Hello again, indeed :) > March 8th - I tested the fishy's water, pH 7.9, ammonia 0, nitrites 0, nitrates 3-4. <Yahoo!> Temperature 74 degrees. Fish was acting normal and ate. I changed 25% of his water (4 days since last change). <Excellent.> Even if the biological filter is working fine we're worried the water might get bad because there's no carbon in the filter. Anyways, again like yesterday in a cup, I mixed 1 1/2 teaspoons of Melafix with some of his tank water and poured it in slowly. Day 7 we had 7 teaspoons of Melafix in her tank and today, day 8 we will keep it at 7 teaspoons. <By number of teaspoons, I do assume you mean by following the directions of one teaspoon daily, yes?> Well she did the same thing today as yesterday. After about 5 minutes of adding the Melafix, she darted around and her dorsal fin was down. <Yeah, it does sound like the MelaFix might be irritating the fish.> She settled down after about 15 minutes and I left the house. Oh yeah, I did add 1 teaspoon of salt to keep the level at about 2 Tablespoons. But this same flashing occurred yesterday without the addition of salt. <I think, from how you describe, that you can attribute it to the MelaFix.> Karen's not home, so I will check on fishy in a few hours from now. You know of any problems using Melafix? Maybe I shouldn't keep it in her water anymore? <As above, I have not seen ill effects from it, myself. I do not doubt, though, that the fish might find it irritating. If it were me, I would probably discontinue using it after seeing what you've described, unless I were seeing very noticeable improvement.> Thanks again <Any time.> Teri, Karen & Fishy <Please do keep us updated. Wishing Fishy a speedy and complete recovery, -Sabrina> Saltwater Goldfish?! - X - 03/16/2004 Hello Sabrina <Hi, Terri!> Thanks for your reply again!! <My pleasure.> Well after adding 1 teaspoon of Melafix daily for 7 a days, we decided not to up the dose but did leave this amount in her tank for another 5 days. Then changed 25% of water and put filter with carbon back in. Didn't add any more salt or Melafix. There still might be close to 2 Tablespoons of salt in tank. <Sounds fine.> Karen says fishy is doing well and seems happy. Haven't noticed any darting around. <Wonderful.> The only concern Karen has is the red part at the bottom end of fishy's fin. This is the only red part left. We think it might just fall off like the one above did a few weeks ago. Except this caused her water to get real stinky and cloudy because it happened during the night. I might have to take some more pictures of her to send to you. <If you could, that'd be great.> The top part of back fin has already grown back about 1 inch! <Excellent, I'm so glad to hear that!> Her water is looking really clean and still tests perfect. We might now consider changing 30% of her water once a week like we used to? <This would definitely be a good idea.> We still have the Kanaplex antibiotics but are very hesitate to use them because of her age and the way she acted with the Melafix? <I have not had any fish react poorly to a low dosage of Kanamycin - including sensitive scaleless fish. I doubt that it would harm your goldie. However, from the sound of it, she's well on the rebound, in which case, medication should be unnecessary.> Oh my, what a 2 months with fishy. Poor thing, with her overfeeding, dirty water and extended salt bath. Lucky she's a hardy one! <Yup! Amazing how durable our fish can be, at times. I think you need to give yourselves a pat on the back for being able to do so much and so well for your scaly bud.> And we're happy that she's now happy. <Me, too.> Please keep in touch. <You bet. Please let me know if I can be of further assistance, and do keep us updated!> Thank you, Teri, Karen & Fishy <Any time - I'm delighted to have been of service. Wishing you well, -Sabrina> Tiny Overstocked "Tank" 3/4/04 <Hi, Pufferpunk here> A friend of mine has this 2 1/2 gallon tank. In it there is three goldfish and one algae eater. The water is so milky and after they do a full water change it turns milky within a couple of hours. Tested water all seems fine. What could be done to help it. <1st of all there are way too many fish in there. The only fish that could possible live in a tank that size, would be a Betta, or a few small white clouds (like 3). A small goldfish needs at least 10 gal/fish & they can grow over 12" each. Every time you are completely cleaning out the tank, you are causing it to recycle all over again. Do a search on WetWebMedia on cycling a tank. Please get a much bigger tank for all those fish. It's ok to be removing a lot of the water every week, because goldfish are messy fish, but you should not be removing everything out of the tank to clean it. Just remove 80% of the water (leave the fish in) & clean the gravel with a gravel cleaner every week. Make sure to add Dechlor & use the same temperature water that is in the tank.> Thank you Georgia Luce <You're welcome. ~PP> Goldfish and Water Quality Hi, <Hello.> I own a Oranda/Lionhead (can't tell which species exactly) and I've just noticed (since an hour ago) that he appears to have some redder than normal red spots on his bubbly head. These are probably indications of blood, perhaps an outbreak; he also seems to have a lot of red streaks in his fins. <Signs of irritation, usually due to inappropriate water quality - do please test for ammonia, nitrite, nitrate, and pH, correct with water changes if necessary.> Usually, he is a very happy swimmer, always upbeat and eager to be fed. Even recently, I haven't seen any abnormal behavior changes, until today. During feeding time, he didn't seem too excited about the food, and kept dawdling around near the middle of the tank. I am terribly worried about what kind of disease/condition he has come up with, as he is a very fond member of our family. <This definitely sounds like he's just having trouble with the water quality.... please test, let us know how it comes out.> Normally, he lives in a 50-gallon tank (estimation) with 8 other goldfish (not Lionheads). To give you a rough estimate of how big the tank is, the dimensions are apprx. : 4 ' long, 1.5' tall (height), 1' width. <Sounds like a standard 55 gallon tank. Nine goldfish is quite a lot of goldfish in this tank; goldfish are really, really messy eaters (er, they poop a lot).> I change the water usually every other week, as I know that ammonia levels can add up (lost a number of fish due to this). <I can imagine so. I would recommend weekly water changes, if at all possible, and some very hefty filtration.> I haven't recently checked the pH, ammonia level/other chemical levels for awhile, as I assume that the water changing automatically makes the tank water suitable for the fish. <Not a safe assumption, unfortunately; testing for ammonia, nitrite, nitrate and pH is the only way we are able to get a real feel for what's going on in the tank. And, when in doubt, water changes *never* hurt.> Back to the Lionhead fish issue, I was hoping you could give me a vague diagnosis of several diseases he could possibly have and what types of treatments are available. <Mm, although there are other slight possibilities, I'm fairly confidant that the problem here is simply water quality. Fortunately, that's an easy thing to fix!> Thank you so much! <Any time.> By the way, I have already started to put him in a "medication/hospital tank" to prevent the spread of disease and to help with treatment. <Likely unnecessary.... I would test your water first (might be a good idea to make that your first step, whenever anything seems amiss), then, if everything checks out perfect (ammonia and nitrite at ZERO, nitrate ideally less than 20ppm, likely higher with so many goldfish in the tank), then we should start exploring other avenues.> I've given him a tablespoon of salt for his 1-gallon make-shift tank. <That's a little bit much for a one gallon tank; I wouldn't use more than a teaspoon or two. Not a big deal, really, though.> Again, I would be most grateful if you could provide any advice or information whatsoever. <So please check your water, and get back to us; I'll be glad to be of further assistance.> Alice <Wishing you well, -Sabrina> Goldfish and Water Quality - II - 03/07/2004 Hello Again, <Hello.> My Oranda seems to have recovered from his previous "streaky-finnage" (streaks on his fins) and blood hemorrhaging on his head. I took him out of his 1-gallon hospital tank today, and put him in his original tank (with the other nine fish). He seems to be fairly happy and well-off, with only a few remaining red streaks on the very tip of his dorsal tail. <Good to hear that.> The pH of my aquarium turned out to be 7, the NH3/NH4 level turned out to be 0, and I didn't check the nitrite/nitrate levels. <Please do make a habit of testing nitrite, at least - it should be considered as toxic as ammonia. Nitrate, though not quite as much of an issue should still be monitored, and kept below 20ppm, ideally.> Thanks for your help! Alice <Any time, glad to be of service! -Sabrina> Goldfish and well water -II Gwen, I purchased some dip sticks to test my water the pH was very high at over 8.2. I put in some pH balance "fizz tablets", tested it again, and it was still high. We have well water, but have a water softener also. For as long as I have had fish, I always bypassed the water softener and used hard water to fill my tanks. Am I correct in doing this? Soft water contains salt and is harmful to the fish, correct? Well I went to the market and bought gallon jugs of distilled water and added water conditioner to it to fill my tank. Noah and another smaller goldfish seem to be a lot happier and healthier. They are both swimming around nicely, but I fear that it may be too late for another one of my smaller goldfish. She seems to be close to expiring. I don't understand why, I never had water problems before, and am having them now. Any ideas? Please let me know if I am on the right track or not. Thank you for all your help thus far. <<Christina, I am not sure if you are doing the wrong thing or not. It depends on how your fish are doing. Goldfish can tolerate a high pH, but they don't like fluctuations in pH, or toxins like ammonia, nitrites, or high nitrates. Soft water is perfectly acceptable, some species prefer a low pH, like discus, and some prefer a high pH, like African cichlids. It just depends on the species. What I do recommend is that you test your pH on a regular basis, to determine if the pH of your well water is stable or not. Diluting it with distilled water is acceptable also, so long as you are making sure that the proportion of dilution is always the same, and therefore the pH is always exactly the same when you do water changes. In other words, if you have put aside 5 gallons of well water at 8.2, and you add 2.5 gallons of distilled water, you should bring the pH down to, well, let's just say you test it and now it reads 7.6. So, each time you do a water change, you know that you must dilute your well water 50% in order to have a stable pH of 7.6. BUT if your well water pH fluctuates, then you will have to change the dilution ratio accordingly.. Make sense? Hope this helps -Gwen>> Goldfish and Water Quality - 04/13/2004 Hi, <Hello, Sabrina here, today.> I have a very large goldfish (he is the only fish in his tank). He started to get Finrot over two weeks ago. When I tested the water, the ammonia levels were extremely high and the PH levels were very low. <Yikes! I think it probably goes without saying, but I will say anyway, please test your water on a regular basis. Perhaps with every water change, 20/20 hindsight, I know, and I know you've learned that lesson, but just wanted to make sure you realized.> I quarantined him for three days and treated him with medication and changed the water in his aquarium. All the tests were fine then. From the time he has been sick until yesterday, he has been lying on the bottom on his side and moves his body across the bottom of the tank. I have been treating the tank with Melafix for the last four days. <I, personally, do not hold a high opinion of Melafix. Though it does not seem to cause any ill effects, I am not convinced that it does anything good, either. Anyhow, that's pretty much irrelevant at the moment, so.... moving on....> As of yesterday morning, the fish constantly sits upright on the bottom of the tank and is very alert. His fins are a little better, but definitely no worse. <Good news, for sure.> However, he has a lot of brown spots on him. I read that this can be seen when a fish is starting to recover from ammonia burns. <Agreed; often one will see brownish hue in the fins, where they were red/inflamed/bloody before, from the ammonia.> The problem is he still isn't swimming and most importantly, he hasn't eaten for 10 days. <YIKES.> I don't know what else to do for him. Are there any suggestions? <Certainly. What have you tried feeding him? I would definitely offer him some greens, like thawed frozen peas (squeeze the shell off, first), blanched cucumber/zucchini, or other goodies. I used to give my goldies asparagus as a kid, just to get the stuff off my plate.... win-win situation, that was. As for the lingering problems from the ammonia, I would like to recommend keeping the tank *VERY* well aerated, first and foremost. The damage you see on his outside is representative of the more dangerous damage to his gills; vigorous aeration may increase his activity level, if he's currently stressed from laboring too much just to breathe. If you are still very concerned about ammonia burns, and feel that it is necessary to medicate, I would try Nitrofurazone ("Furacyn", by Aquatronics, for one proprietary name). This is a very mild med, and supposed to help with issues from ammonia poisoning. I would not medicate, though, until after seeing if vigorous aeration and tasty veggies don't bring him about.> Thanks. <You betcha. Good luck with your goldie, and please feel free to write in for further assistance, or if you wish to update us on his progress. Wishing you well, -Sabrina> Goldfish help Hello. I have just finished reading several of your articles, but still have some questions. Help! I have had a 20gal tank for a couple of years now. I have gone through several tropical species and have learned a lot through trial and error. Well, finally I thought my tank was going to be set when I got 2 fantail goldfish. For a few months, everything seemed fine, though I noticed that they dirtied up the tank a lot more than my other fish ever did. Anyway, about two weeks ago my water started getting cloudy, so I did a water change and even added an ammonia removal media to my filter. I am really struggling with my water quality. The PH is really low and I can't get it up and stay there. And no matter what I put in it, the ammonia levels stay above 2ppm. As you can guess, one of my fish died. I did another water change, but the ammonia levels are still off the charts. Now, if it doesn't die that is, I have one lone fish. Once I get the water stable, should I add another goldfish? He already looks so lonely. Currently, he is 4 inches. I need some advice on both points. Could my struggle with the water quality be due to the gravel - I read somewhere that goldfish tanks should not have gravel? Should I clean it more often than every other week? Was 2 four-inch goldfish simply too many for a 20gal tank? Thanks Jamie < Don't add any more fish until you get your tank chemistry under control. First is the ammonia. It should read zero. Don't feed for awhile. Vacuum the gravel with a 30% water change and get all the junk out of there. Gravel is fine if it is cleaned. Check the ammonia again. If you still get a reading then service the filter. Get the ammonia levels down to zero with water changes or ammonia removal media. When you have a zero reading then you can feed your fish only enough food that it will eat it all in a couple of minutes. Overfeeding is a major cause of ammonia problems. The ammonia should then be converted to nitrites and then nitrates. The ammonia and nitrite levels should read zero. Nitrates should be no higher than 25 ppm. - Chuck> Oranda and Indianapolis water Hello! <Hi
there> Just needed to ask a
quick question, first the info... I have recently set up a 10 gal tank
in the office for 1 juvenile (1 1/2" w/o tail) Red Cap Telescope
Oranda (cute!). <Very cute, was just given one just like it as a
birthday gift for my office tank! Delightful and beautiful
fish.> After using a de-toxifier for our chlorine, chloramine, and
ammonia in the water, I let the tank sit for a few weeks with the power
filter and aerator running. <Good man! I see many people
simply get a tank and fish and put them together at the same
time. Letting the tank sit and run is one of the best things
you can do for the long term health of the fish!> I added Bio-Spira
along with the fish to the tank 6 days ago. Fish is happy, swimming and
eating and looks great. <Congrats>
From the beginning I have had daily
test results of .25-.5ppm ammonia (same as the water source), and no
nitrites, and nitrates at 20-25ppm (again same as water source) PH is
7.6-7.7. <Not unusual in city water settings. Takes a
little bit of extra work to get things to stay balanced, but nothing
too hard.> Water did get a bit hazy and bubbles would collect on the
surface after I fed flake food instead of the sinking pellets,
<flake food breaks down a bit quicker in the water than the sinking
pellets it adds extra nutrients and such to the water which feeds the
bacteria. Just be sure to not over feed the tank, only feed
what the fish can eat in few minutes. If possible you can
offer really small meals throughout the day rather than a large meal
all at once.> did a 25% treated water change on day 5 by
vacuuming the gravel and it helped a bit (not gotten worse since).
<Keep up with this, since your city water is not the best to start
with you will probably have to do water changes quite
frequently. Also since the fish is only in a ten gallon
tank, the water quality can get bad quickly since goldfish produce such
a great amount of waste and ammonia.>
I was wondering - after these days
of feeding 2x daily would the chemical tests be indicating that the
Bio-Spira worked and I have a cycled tank, or is it too early to tell?
I have not seen an increase in ammonia nor nitrate levels over what is
in our wonderful municipal water originally, and would expect to have
seen that by now if it were going to happen. Am I correct in my
thinking? <You are correct; at least that is what I'm
thinking. I doubt you should have any problems provided you
don't over feed the tank and you keep up on the water changes.>
I will be testing daily for several weeks anyway. Also, is the level of
ammonia present (.5ppm) in our water supply stressful to the fish at
all after I add a ammonia Detox? <It's kind of a debatable
topic. I say it is slightly stressful, but you are adding a
detoxifier in the water so it shouldn't be that
bad. Also goldfish are pretty hardy fish. I had
fish in water very similar in my previous office and they became
accustomed to it and thrived for many years. I did notice
that their growth was a bit slower than the ones at my home (luckily
natural spring water bubbles up out of the ground at my
house). Just realize that you should test at least once or
twice a week as the months go on. Gradually you should get
the hang of the system and only need to test sparingly. But,
I don't foresee any extremely bad situations happening.>
If the level of ammonia does indeed
go up- at what level (ppm) should I do a sizable water change for the
safety of the fish (considering my water already shows at .5ppm)?
<If your levels do become quite high you shouldn't do a massive
change at once. Do small ones every day rather than a 50-70%
water change. I find this is less stressful on the fish and
less likely for them to possibly get ill. But, if the
levels get around 1.5ppm I would be concerned and getting them
down. Over 2.5ppm then I would be very worried.> Thanks
for all your help and the great information on your website. <Glad
we can be of help! That is what we are here for. -Magnus>
