Tank Setup... FW... need to read; WWM, books...     2/16/08
Hi Neale,
<Neervana,>
I just bought an aquarium that is 640 litres. How many gallons is that?
<Time to learn how to use Google I suspect. Type "640 litres in Imperial gallons" or "640 litres in US gallons" (without the quotation marks) into a Google search box and off you go. It's about 170 US gallons, or about 140 Imperial gallons.>
Its just that so many shops online have the US gallon thing)? And how much gravel should I buy to fill that (want a good layer of gravel)?
<No idea. I'd start off with a 3-4 25 kilo bags and see how you go.>
Also, how many fish would I be able to put in there?
<Depends on the size of the fish. There's no "golden rule", but broadly people tend to suggest 1 inch of fish per gallon or 1 inch of fish per 10 square inches of surface area. That's fine for Neons and Guppies, but pretty meaningless for anything very much bigger.>
I'm not sure what equipment should I get (air pump, lighting etc) I will have to order it online because my LFS does not have that kind of equipment.
<Read an aquarium book or visit the "setting up" pages here at WWM, and all will be revealed!>
I want to put two silver dollars in there and a Black Ghost Knife (only when its cycled like you said).
<Cool. I'd recommend at least 6-10 Silver Dollars in a tank this size. For one thing, these fish look amazing in big groups. Secondly, as "dither fish" they will help your other fish feel more secure.>
I'm putting the pictus in with the sharks at the end of this week, it seems to be doing fine. All its fins are healthy again like when I first bought it. I'm just happy that we managed to save one out of the two that I had.
<Live and learn.>
The tank is coming with a stand - do I still need to put some polystyrene underneath the tank before putting it on the stand?
<Depends on the system. Some tanks MUST NOT have polystyrene between the glass and the wood because there is a plastic trim that takes the stress instead. The JUWEL tanks are like that. So check the instruction book that comes with the tank.>
What other fish do you think I could have in my tank I don't like a lot of colour.
<Oh, many things. A couple more Bala Sharks perhaps. Bichirs (Polypterus spp.) are always fun in big tanks. Clown Loaches perhaps? Or some other schooling Loach of reasonable size not to get eaten. A nice wild-type Oscar would be fun. Really many choices.>
I was thinking about getting the plec you told me about, when I have finished cycling it, but I'm not sure.
<Plecs are always fun, but certainly not essential. The idea they "clean the tank" is a myth, so by all means keep something else.>
Thanks, Neervana.
<Cheers, Neale.>

Re: Tank Setup    2/16/08
Hi Neale,
<Neervana,>
Sorry I forgot to add something in my previous e-mail. Will my floor support this tank?
<I have absolutely no idea. This is the kind of thing you need to discuss with someone qualified in building or engineering. As a rule, aquaria are safe enough on ground floors, particularly when placed across several joists rather than along just a couple of them.>
My 200 gallon one is in the sitting room, ground floor and is fine - I want to put the new tank in my bedroom as it is rather spacious, but I don't know if it will be able to support it's weight.
<I do not know either.>
It is on the ground floor, and there is no "basement" beneath it, I read online that it's not advisable to put aquariums on floors that have a basement beneath it.
<It's not really whether or not there's anything underneath the floor, but rather whether the floor has sufficient structural support to carry the extra weight. If in doubt, consult someone who knows about this sort of thing.>
Can I send pictures of the tank and how the set up is going? I want to take my time and do it properly with your advice too. It will take ages for me to set up the tank, but that's the part I enjoy the most so I don't mind!
<By all means send SMALL photos (less than 500 KB). Don't send BIG pictures (i.e., not what comes straight out the camera). If our mailboxes fill up because of your one e-mail, it's a bit unfair on everyone else sending text messages. Also, do consider joining a tropical fish forum of some kind. I happen to like 'Tropical Fish Forums' but there are plenty of others, including ones run by fishkeeping magazines including PFK, TFH, Aquarium Fish International, etc. Most of these forums have aquarium gallery sections, where people can post photos and chat about design and aquascaping. I think you'd find that interactive and fun. Think of the Wet Web Media Questions & Answers section as the place to come for help rather than chit-chat. Certainly I enjoy spending time at forums when I want general comments and advice.><<Amen... RMF>>
Thanks, Neervana.
<Cheers, Neale.>

Ceramic media, air pumps... FW set-up   01/13/2008
Hello Neale,
since the last email I bought from a friend a 46-gal acrylic tank (20 inches deep, 36 inches wide) and I'm now working on the aquascape project before actually running it. In other words, the tank is empty, but I pretty much have the project on paper. I also bought a compact fluorescent lights kit which is 130W, because I'm planning to make it a serious planted aquarium. I have a few questions that I'd like to ask you:
1. Considering the 130W lights, do you see issues in using plants such as Java Moss and Java fern which require low light? More in general, given the high amount of light, do you think it would be an issue to keep plants requiring low/medium light levels?
2. Do you think it's fine to cycle the tank with 6 Pristella?
3. Once the tank is mature, I'd really like to include some dwarf cichlids in it because I really like them. Initially I was thinking about Rams, but then considering the high temperature they need, which would be probably fatal for other fish such as neon tetras as well as for some plants, I thought about Kribensis and/or Apistogrammas. What do you think?
4. Regarding the substrate, do I need to use an undergravel heater? Would a mix of fine gravel and laterite be enough? I read that I should also put some peat moss at the bottom of the tank to allow the laterite to be absorbed by the plants. Is that true?
As always, thank you so much for answering all my questions.
Sincerely,
Giuseppe

Re: Ceramic media, air pumps    01/13/2008
Hello Neale,
<Giuseppe,>
I believe my email starting with '...since the last email I bought from a friend a 46-gal acrylic tank....' has not been answered. I suspect you answered a previous email. I'm sorry for the confusion and thanks again for your help.
Giuseppe
<Hmm.... I just answer what's in the Inbox... Is the following the message?>
since the last email I bought from a friend a 46-gal acrylic tank (20 inches deep, 36 inches wide) and I'm now working on the aquascape project before actually running it.

<Low-light plants are fine in bright tanks, but almost by definition they grow slowly and are easily overwhelmed by other species. Things like Java fern and Anubias also tend to get covered with algae. So place low-light plants under the shade of other plants.>
2. Do you think it's fine to cycle the tank with 6 Pristella?
<I wouldn't cycle any tank with tetras really, but yes, Pristella maxillaris is at the hardy end of the spectrum. So assuming you did your level best to reduce nitrite/ammonia through water changes, they'd be fine. They're also salt-tolerant characins (a small group!) naturally inhabiting slightly brackish water, so you could use tonic salt to ameliorate nitrite toxicity somewhat, at least initially.>
3. Once the tank is mature, I'd really like to include some dwarf cichlids in it because I really like them. Initially I was thinking about Rams, but then considering the high temperature they need, which would be probably fatal for other fish such as neon tetras as well as for some plants, I thought about Kribensis and/or Apistogrammas. What do you think?
<Apistogramma are great in planted communities and appreciate moderate temperatures, unlike the Mikrogeophagus ramirezi. So something like A. cacatuoides would be a great place to start. Mikrogeophagus altispinosus is also very good. Almost any of the Pelvivachromis species are good too; if you shop around, you'll find more than Kribs on the market. P. subocellatus and P. taeniatus are both very beautiful.>
4. Regarding the substrate, do I need to use an undergravel heater? Would a mix of fine gravel and laterite be enough? I read that I should also put some peat moss at the bottom of the tank to allow the laterite to be absorbed by the plants. Is that true?
<Substrate heaters do have a (small) positive impact on plant growth, so if the (slightly more expensive) option of using one is viable for you, go for it. Fine gravel and laterite works very well. Put the laterite layer as the bottom 50%, and then plain gravel as the top 50%, otherwise the fish make a mess. A gravel tidy between them is helpful. Used this system myself, and back in 1980s was considered the "Optimal Aquarium" to quote the Germans who wrote on such things. Obsolete now I suppose, but still good. Never heard of the peat moss thing. Sounds a bit daft to me. What plants prefer is slightly anoxic, but not completely anoxic conditions. So a deep gravel bed with under-tank heating is ideal, because the flow of water from the heat (convection current) is just enough to keep the water in the gravel slightly but not fully oxygenated. So you get reducing chemistry in the substrate, and this allows the plants to absorb iron and other elements properly. If you look at where aquatic plants grow, it is usually very black and smelly mud!>
As always, thank you so much for answering all my questions.
<No probs.>
Sincerely,
Giuseppe
<Cheers, Neale.>

Fish Question... Very new FW... for a baby... Basic set-up, cycling  12/21/2007
Hello,
I am attempting to do a fish tank for Christmas for my 2 year old. (You should see her face in the store, much less all the screaming!)
<Welcome to the hobby, both of you.>
So, we bought an Eclipse 6 gallon from Petco.
<Ah, a 6 gallon tank is extremely small and very, very, VERY difficult to look after. Paradoxically perhaps, the smaller the tank, the more hard work and the more expensive in the long run. This is often overlooked. I'd highly recommend absolute beginners to work with a 20 gallon tank -- about the minimum size for an "easy ride". Anything smaller gets difficult.>
It has a Marineland BioWheel in it. I have never done fish tanks before and I have been reading everything I can get my hands on, including your FAQ which I must say has been quite helpful. I also picked up a book by Boruchowitz. I have put the water in, of which I have used my Pur filter on my faucet, and I have purchase a test kit for Ammonia and Nitrate, liquid ones as suggested. As far as I can see, platys are pretty good starters, so I plan on going with those. I just have a few questions to make sure I don't kill these things.
<Platies can be good fish, but they're far too large for a 6 gallon tank. A tank this small needs fish that stay below 2.5 cm/1", which really limits you to things like bumblebee gobies, cherry shrimps, Corydoras habrosus, dwarf mosquitofish, ricefish, and so on. Adult female platies are fairly substantial fish, around 5 cm/2" and quite chunky. While I dare say they can survive in a 6 gallon tank, I'd question whether mere survival is the baseline we're going for here.>
Does it help at all if I use my Pur filter?
<Not really. What they are is activated carbon packaged incredibly expensively. While you may appreciate the taste difference, your fish couldn't be bothered either way. Dechlorinator to remove chlorine and/or chloramine is more important, and in the quantities required to maintain an aquarium (50% water changes per week) using drinking water filtration systems will be ridiculously uneconomic.>
We have a water softener, Should I turn it off when I am changing the water?
<Never, ever use water from a domestic water softener in an aquarium. Draw the water from the unsoftened tap in your kitchen. The sodium-rich "softened" water is as bad for the fish as it is for you, in fact more so.>
Do the test kits have a shelf life?
<Yes, typically a year, though this varies. Keeping them somewhere cold and dark, like a fridge, extends the life.>
I do not want any babies since this is only a 6 galloner, is there a hardy fish that gets along well that doesn't breed well? I'm scared of that with the platies..
<Not a chance. The two platies already have filled the tank, AND THEN SOME! Besides, the parents will likely eat any fry unless you remove them, so don't worry about it. Should you be blessed with a few babies that survive, return them to the pet store. No big deal.>
Are 2 female platies the best mix for not fighting and such, or do they get sad without a man around?
<Two platies will be perfectly happy on their own.>
When they say "school" I think of 6 or more fish. Is a school only 2?
<A school is indeed at least 6 fish; smaller than that and the school doesn't work. What happens then varies, but possible problems include fighting, chasing, nervousness, and even pining to death. Depends on the species. Cheers, Neale.>

Re: Fish Question 12/21/2007
Sorry, forgot to add that the test kits don't have an exp. date. Ammonia test is from Nutrafin and the Nitrate is from TetraTest.
<Expiration date is usually a year. Perhaps longer if kept cool and dark. Cheers, Neale.>

Re: Fish Question 12/21/2007
Just tested the ammonia and nitrate
Ammonia: 1.2
Nitrate: 12.5
Does this mean it hasn't cycled yet?
<Indeed. Ammonia and nitrite (with an I) need to be at zero. Nitrate (with an A) goes up between water changes. A nitrate level of 12.5 mg/l is fine. Ideally keep it below 20 mg/l but don't be too worried about it. 50% water changes each week, plus avoiding overfeeding, should manage nitrate easily. Cheers, Neale.>

Re: Fish Question, FW stkg.   12/23/07
The book by Boruchowitz claims that a 5 gallon fish tank can hold 2 platies, 3 zebra danios, 2 cherry barbs and 1 Cory cat.
<Hmm... I know David B. through his editorship of the TFH Magazine and we consequently work together periodically. In fact, I have an article coming out early 2008 specifically about stocking small (10 gallon) tanks, and David and I worked together on refining the list. Anyway, that list of fish you suggest here simply doesn't make sense. Corydoras are SCHOOLING animals and need to be kept in groups of at least three specimens and ideally six or more. Danios likewise MUST be kept in schools of at least six specimens. Cherry barbs might work in small tanks, though they are hardly fish I'd casually recommend because they are quite delicate and have sometimes schooling/sometimes territorial personalities that need to be worked around.>
Another mix he recommends is 2 gold barbs, 3 white clouds and 2 swordtails. That's where I was getting the idea of what and how many...guess he's not correct.
<For a 10 gallon tank? Gold Barbs -- if by which he means Puntius semifasciolatus -- are big fish, up to 7 cm/3 inches and absolutely cannot be kept in a 10 gallon tank. They're also subtropical fish, and while that makes them good companions for White Cloud minnows, Swordtails would be too cold in subtropical water conditions. White Cloud minnows need to be kept in the same way as Danios, and that means groups of 6 or more. Swordtails cannot possibly be kept in a ten gallon tank; adult males are incredibly aggressive for a start, and both sexes are big, fast-moving fish that need at least a "long" 20 gallon tank.>
Glad I asked!
<Everyone has their opinion on minimum tank sizes, but to some extent you have to be intelligent about it. A 6 gallon tank is essentially a bucket in terms of volume. Which fish -- as adults -- would be happy in a bucketful of water. That's what you need to ask yourself. For me, the answer is non-schooling, relatively inactive fish around the 1 inch/2.5 cm mark.>
I know the tank is small, but so is our house (700 sq feet!) It's a good size for where I have to put it.
<I sympathise. I own a small terraced cottage in England, and finding space for my fish is always an issue. But on the other side of coin ANIMALS AREN'T ORNAMENTS. They live, feel, and suffer. If you've decided to get a pet, then you have to provide AT LEAST the minimum that animal requires to be healthy and happy. And a 6 gallon tank is very much borderline as far as Platies go. Children as young as 2 years aren't really going to learn much from a fish tank, and ultimately the lesson children have to learn is that animals come with responsibilities.>
There is no way we could do 20 gallons without having a stand, and that will be a big watery mess on our carpet in 5 seconds flat with our daughter and 50 lb dog.
<Maybe, maybe not. If your house is too chaotic for a fish tank, then perhaps a fish tank isn't right for you?>
It's right on our kitchen counter, so the water changes won't be hard at all, and I plan to do them frequently.
<Good; you'll need to! A 6 gallon tank will get polluted extremely quickly, and you'll soon find the water cloudy and the tank infested with algae. Trust me on this.>
What I can't understand is how I have so much ammonia (1.2 mg/ml) and I haven't added any fish...
<Check the tap water first. Perhaps you have ammonia in there. Also check your dechlorinator -- some brands turn chloramine into ammonia but then do nothing with that ammonia. Are you cycling the tank in some way, e.g., by adding a pinch of food every couple of days? In this case, you may be adding too much food (or whatever ammonia source). To cycle the tank in this way takes about 6 weeks, so the filter won't be mature until then.>
do I just trust the BioWheel to get rid of it?
<Trust nothing except your test kits. Only add fish once the ammonia is at zero; ammonia quickly kills aquarium fish.>
If I change the water, theoretically the ammonia will just stay the same, right?
<Depends; water changes should dilute the ammonia if the ammonia is getting into the tank via fish food (or fish). If the ammonia comes from the tap water, that's very bad, and you need to use ammonia-removing dechlorinator before adding that water to the tank. Cheers, Neale.>

Re: Fish Question  12/23/07
OOO...a cottage in England...like a fairytale. You must love it.
<I do indeed!>
I went through vet tech school, so I am aware of the necessities animals demand.
<Very good.>
Can't say we ever had a chapter on fish...which now that I think about it that's kinda sad because it seems there's not a lot of people that are well educated on this out there.
<Ah, yes, a topic for discussion on another day. It is sad that many vets aren't able to offer advice to fishkeepers, but there are some vets who handle fish. Generally the bigger species like koi that respond well to medication and surgery. For smaller fish -- like Platies -- the name of the game is prevention rather than cure.>
Anyway, that chart is on page 92 of the animal planet freshwater aquarium book. I think I may be reading it wrong. I think it's just saying the number of fish per species...like for a 5 gal. 2 platies or 3 zebra danios or 2 cherry barbs or 1 Cory cat. Does that sound better?
<Possibly; if the book was suggesting allow 5 gallons per Corydoras or two platies, that might make sense. But without reading the book myself, I'll hold fire on being too critical.>
As for the tank...I tested it last night and it was more like 2.4 ammonium. I heard adding rocks from another established tank may help, so I did do that, but I'm guessing with it being so high it'll just kill the bacteria anyway.
<Hmm... doesn't really work this way. The bacteria will come into their own in time. They are in the air and water as spores of some sort, and once the aquarium is filled with water the bacteria settle and multiply. Simple as that. Adding rocks doesn't make a huge difference. Most of the bacteria in an aquarium are in the filter media. So "seeding" the tank with filter media from another tank helps dramatically, to the point where the tank matures essentially instantly if you add enough mature media. But adding rocks and water from an established don't have much impact.>
Just tested the tap, and it's somewhere between .6 and 1.2...not good.
<Indeed. Do check whether you're adding the right kind of dechlorinator. Water suppliers use chlorine and/or chloramine. To get to the science, old-style dechlorinator neutralises the chlorine, I think using a thiosulphate salt. This is fine for water sterilised with just chlorine. If the supplier uses chloramine instead (or as well as) then the thiosulphate splits the chloramine and neutralises the liberated chlorine but leaves the remaining ammonia in the water. The other source of ammonia in water is contamination. Some water gets ammonia in it from agricultural run-off, for example. Ammonia neutraliser will need to be used to eliminate this before adding it to the tank. Ammonia is incredibly toxic, and over the medium term even low levels will dramatically increase the risk of sickness even with hardy fish like Platies.>
I did get some ammonia neutralizer, added it last night, and that seemed to bring it back down this morning, so I imagine that I'll just keep doing that until I can get my ammonia down.
<Agreed. Ammonia is a deadly toxin, and needs to be treated as such.>
As for water changes, I suppose that I'll have to add some of this ammonia neutralizer along with the conditioner before I do them.
<Yes.>
I haven't added any fish food, just water and decor, so I suspect it's my lovely hillbilly water. Can/should I double the recommended dosage of the ammonia neutralizer?
<Add until you get zero ammonia; excess neutraliser and/or dechlorinator is FAR LESS of a risk to life than ammonia.>
Do you have any recommendations for the conditioner? I used TetraAqua AquaSafe with BioExtract. Does that leave me with a heap of ammonia?
<Hmm... I'd tend to go with either AmQuel or AmmoLock in situations like this. In theory, you could also treat the water by filtering it through Zeolite before using it in the aquarium, but that'd probably be a lot of hard work.>
Also, how do you feel about bio-Spira?
<Used properly it CAN work very well. But it isn't 100% reliable, so if you do choose to use the stuff, follow precisely as indicated on the package, and then do water tests every couple of days across the next few weeks to make sure it has worked properly and there's no massive ammonia or nitrite spike after introducing the fish. Cheers, Neale.>

Re: Fish Question... cycling   12/24/07
Got some bio-Spira last night and put it in around 11.
<Very good.>
By 4 today, I actually have readable nitrites! I suppose that means it's working, because before I had no nitrites at all.
<Indeed! This is how it works...>
Ammonium is still high. It went back up with the water changes, like I suspected. I'm afraid now to use the ammonia neutralizer because the bio package said that some ammonia neutralizers work against it.
<I do see the logic here. The filter bacteria do indeed need some ammonia. HOWEVER, if you remove the ammonia from each new batch of water (so that if you test the new water, the ammonia is zero) and THEN add it to the aquarium, things will be fine. Just add fish food or a small (1 cm) piece of seafood; as this decays, it will produce enough ammonia to keep the bacteria in their happy place. In a properly matured aquarium the fish produce the necessary ammonia; you don't need any from the tap water!>
Frankly, I was afraid to add it, but since I see the nitrites I assume something is going good. I'll keep you posted, thanks for the help!
<Hope this helps, Neale.>

Re: Fish Question   12/25/07
It would be an act of God for me to have 0 ammonia with my tap. When I did the water change, the new water was reading at .3. And like you said, if I ever need ammonia, fish and their food will take care of that.
<That's the theory anyway. But I have to confess to never having used Bio Spira. In any case, I'd worry much more about reducing the ammonia than anything else: ammonia is deadly to fish, and there's no advantages to leaving it in the water.>
However, I read the bio-Spira as it saying the ammonia reducing chemicals will kill the bacteria. But if it's just the reduced ammonia, then I'll be fine there.
<That would be my thinking, too.>

Re: Fish Question... newbie, FW... heater... needs to read a complete tome    12/25/07
also, it has been suggested that I set up a bucket and use a zeolite filter in it with a heater along with the ammonia neutralizer 48 hours before water changes. What is your take on that?
<Certainly worth a shot. Best try it out and see what happens. So long as you get zero ammonia in the new water before adding it to the tank, it doesn't matter how you do it!>
Also, my tank has kept a steady 78-80 with no heater. The light gets pretty warm, so I think that's what it is. If it fluctuates, should I get a heater?
<Hmm... try and figure the minimum temperature. If the tank fluctuates between 80F in the daytime and, say, 68F at night, that's fine for most community fish. It is, after all, what happens in the wild. Only a relatively few freshwater fish need very constant temperatures.>
If I do get a heater, how do I keep it from getting too hot? The reason I ask is because we have kept the tank under a towel this whole time to keep it a secret from my 2 year old, so something is telling me that now the towel is off, it won't stay warm, however, 80 is up there, so I can't see it going below 75, because I keep my house around that.
<Get a heater. Heaters automatically switch on and off. While shopping for heaters, you'll see heaters are rated for tanks of certain sizes. Avoid getting a heater too big or too small for the tank you have, or you may have problems. Cheers, Neale.>

Re: Fish Question... heater... chatting... now pH...  12/25/07
oh, wow. I heard that if the temp fluctuates more than a degree, it's bad.
<Depends on the fish. Things like Corydoras and Danios positively enjoy moderate changes in temperature, and can be kept outdoors in places like England during the summer. Other fish, such as Angels and Discus, need much more consistent temperatures.>
I will keep a close eye on the temp for sure. It has never been below 77. If I have a problem, a heater huntin I will go!
<OK.>
Nitrites are testing at 1, while ammonia is somewhere between .3-.6. Are fish ok to add?
<No, far too much of both.>
I also tested the pH and that's not even readable on the chart.
<Obviously not good. Do check you are using it properly. Most community fish want a pH between 6 and 8, though some fish, particularly the livebearers (Guppies, Platies, etc.) MUST have a pH above 7.0, and ideally 7.5 upwards. Cheers, Neale.>

Re: Fish Question... a referral in time saves Bob's mind...  12/25/07
I know that the pH is way up, at least 7.6 because it's light blue on the chart and that's the color I got. Platies should be happy eventually...
<Yes, pH 7.6 is good for Platies. But besides the absolute value, what also matters is the pH stability. You want the pH to fix at 7.6 day in, day out. If it bounces about between each water change, then you have a problem. Very small tanks (10 gallons and less) in particular are very prone to this problem, which is one of about a million reasons why they are bad choices for beginners. Cheers, Neale.>

Filtration help... FW set up Qs, learning to read/use WWM   12/18/07
Hi there, first I just want to say how much I appreciate the staff there who run this site and answer questions so fast. you guys are great and have helped me so much with my learning process, keep it up!
Now, I have an established 10 gallon tank and am wanting to setup my 30 gallon and 5 gallon tanks (haha Multiple tank syndrome!). The 10 g has a small AquaClear filter on it currently. Yesterday I added the large AquaClear filter and a small sponge filter to the 10g to try to get the media colonized with bacteria.
My questions are: How long do I have to leave the new filters on the established tank for it to be colonized so that its good to go on the new tanks?
<Read here: http://wetwebmedia.com/FWSubWebIndex/fwestcycling.htm
and the linked files above>
I would like to get this on my new tank as fast as possible so I can put Bolivian rams in it...(long story I know they should be put in last, but where I live they never usually come here and they have been sitting in the store for 3 weeks and I wanted to get them before someone else snags them).
<Can be "goosed"...>
Also there is much happening in my 10g right now, with all the bubbles and movement, 1 of my baby panda cories got sucked into the uptake tube last night (I was sooooooo sad/mad...I'm getting so attached to them!) and it died. I feel terrible that it must have died a slow and painful death. The other fish (3 baby pandas, 4 tetras, 2 harlequins) don't look too happy right now, I had to change around the decor a lot..I just put nylon to cover the large filters uptake tube but will this interfere with the colonization process?
<No>
Is it possible to have TOO much oxygen or movement in a tank?
<Not practically>
Also the sponge filtration unit is meant to eventually go on a 5 gallon with a Betta, it seems quite noisy and bubbly.. will the Betta be ok with it?
<Likely so>
What I did was I tied 2 knots into the tubing to slow the rate of air coming out of the pump, will this wreck the pump due to backflow?
<Back pressure? Perhaps shorten its effective "life">
Finally my last set of questions...I bought a bunch of driftwood to put into each tank.. about 1-2 pieces each.. I bought them to soften the water a bit since water is very hard here. I don't want to boil them because I want them to leach tannins, is this ok, can I just soak them?
<Can>
How long should I soak the pieces for?

Is there such thing as too much driftwood?
<Yes>
I don't know my water hardness but I know its very hard. How long will it take for the tannin levels to be established...what I mean is do I have to constantly monitor pH, or say after 1 month that pH that its at it will stay there?
<See WWM re FW pH...>
Sorry I hope it makes sense. I take out the carbon to have the tannins in the water, is this correct or do I leave the carbon in?
thank you so much!

Beginner needs help, FW... set-up... pH    11/08/07
I have been reading for days on your site. I appreciate all the information, but have been unable to understand what is going on with my tank.
<Fire away!>
I have a small 10 gallon freshwater tank.
<Ah, too small for beginners in my honest opinion. Small tanks are unstable and problems spiral out of control very quickly. Advice to other beginners: start off with a 20 gallon tank if you want an "easy ride".>
I was using distilled water and had plastic plants with tetras and a guppy.
<Why? Distilled water is completely unsuitable for aquarium fish or indeed any living creature. Tap water is much the best for beginners, though dechlorinated of course before use.>
We kept the tank for about 6 months with no problems. Our guppy just died one day.
<Surprised it took that long...>
We decided we wanted to have some ghost shrimp, an algae eater some live plants. The ghost shrimp died right away.
<Not a surprise at all].>
We now understand they are not that hardy. We were told our water was soft when they tested it at the pet store. they thought we could use tap water in our area with some aquarium salt and prime.
<Sheesh. Pet store advice strikes back. Please, over the next few days remove a portion (20%) of the water in your tank and replace with dechlorinated tap water. Do not add salt. If your local tap water is soft and acidic, then don't keep fish that need hard and alkaline water (such as guppies). Stick with genuine soft water fish, such as tetras.>
Our ph seems to stay around 7.4 no matter what we do.
<That's a fine pH for most fish. And a stable pH is a GOOD thing.>
We added some sea shells as told to.
<Why?>
We drain and add every week and a half to two weeks. We have been doing about the 20%.
<Change 50% per week. This is the cheapest and easiest way to keep a happy collection of fish. Few problems can't be solved by dilution.>
Our tank looks beautiful, water looks clear, we ended up with 2 snails on the plants.
<Water clarity is irrelevant in keeping fish. You can have clear water that kills fish overnight, because ammonia (for example) is invisible. By contrast the water most fish live in looks like milky coffee and yet they (obviously) thrive.>
the water was running a little warm (80-82 degrees) but we changed our incandescent bulbs out for the fluorescent.
<Good. Very few fish like water this warm, and some will have dramatically shorter lives when kept thus. Aim for 25C/77F; no higher.>
There are some very strange tiny hair like, things for lack of a better word, on the glass of the tank. They are tiny, barely can see them attached with one piece with like three hair like things off them.
<If static and whitish, that's mould or bacteria. If static and green, it's algae. If mobile and whitish, then nematodes. Not problematic in themselves, but potential clues to other issues.>
Also we have sand in our tank instead of gravel.
<Sand is fine, just keep it clean.>
Do you have any advice for us?
<Read an aquarium book or this web site. Relying on local fish store advice can be tricky. Shops want to sell you stuff, and largely don't care if your fish live 6 weeks or 6 years, so long as you come back and buy more fish and other products. Educating yourself is the key to solving your own problems, and using your pet store as a resource for essential purchases.>
What do you think these little things are? Also, one of my tetras looks a little stressed. His stripe does not look right like he has faded.
<Fish do lose colour when stress. Water quality, water chemistry, diet, bullying can all be factors. Need more data.>
I am worried I have done something wrong. I did notice you said in many articles not to overfeed. Our fish eat all the food at the top of the water when we feed. We are very careful about that.
<Very good.>
Is my ph really messed up for another reason?
<A pH above 7.0 can be caused by two main things. One is good: calcium carbonate in the water. This raises the carbonate hardness (measured with a KH test kit). Guppies and other livebearers love carbonate hardness, and carbonate hardness also buffers the pH in the tank, keeping it steady. The bad source of a pH above 7.0 is ammonia. So test for ammonia (or have the pet store do it for you). Ammonia is a severe poison.>
Does the sand really mess up our tank?
<No. But not all sand is equally good. Some sand is calcareous (e.g., coral sand) and will raise carbonate hardness and pH; other sand is non-calcareous (e.g., silica sand) and has no effect on water chemistry.>
It seems like with plants we are reading a lot about gravel.
<Depends on the plants. Non-rooted plants like Java fern and Anubias couldn't care less, and actually get unhappy (die) if stuck in the sand or gravel at all. Most plants prefer sand to gravel, because the slightly anaerobic conditions in the sand shift mineral ions into their reduced (as opposed to oxidised) states, making them easier to absorb. By itself, plain gravel or plain sand aren't really suitable for growing plants anyway, no more than land plants would grow if you stuck them in a flower pot filled with gravel or sand. To get good plant growth, you need to augment the substrate with something else, like aquarium soil or laterite, that contains minerals like iron.>
Thanks for all your help.

Non Planted FW aquarium.  10/20/07
Hi Neale!
<Hello Bryan,>
Once again I am need of more sage advise... my girlfriend just got back from a family trip back east, about halfway through the trip she told me that she had found something that we could "do together" and was bringing it home with her. when she got home she presented me with a book called "Aquarium Style" by Matthew Christian. which surprised me, because to this point the only thing she has ever said about my hobby is "You got another _____ing fish tank!? are you out of your mind!?"
<Ah, I do know this book. Not sure what to make of it. On the one hand, a book demonstrating all the different ways a freshwater aquarium can be put together is a brilliant idea. And the ideas given (while not all to my taste!) are certainly interesting and attractive. But on the other hand, some of the tank ideas seem to me to be flawed. The author seems to make no account of things like social behaviour, adult size, stocking levels, etc. So while the tanks *look* great, I'm not sure that in the long term, the fish populations used are appropriate.>
The book itself is interesting, and quite a bit different than the usual book that I would read, it is very heavy on visuals and doesn't bog the reader down with long texts and big Latin words (my usual preference) it is no doubt designed to capture the interest of beginners and bring them into the hobby by showing 30 or so "themed" tank designs (some very practical and sustainable, others not so much... unfortunately she has taken a shining to the later) unfortunately there are some pretty big red flags if one reads the text... from describing live plants as "good if you want a natural look or to give your fish a place to hide" to recommending 15-20 tiger Oscars for a "medium sized tank" and suggested stocking levels that border on obscene for all of the tanks...
<Exactly my sort of concern.>
but the aquascapes presented are all captivating and well thought out, even if some of them probably crashed within days (or hours) of the photos being taken... anyway, I’ll get off my soapbox now and get to the heart of my question. As I said before, this is the most interest she has ever taken in my hobby and I don't want her to lose that interest by telling her that the tanks she thinks are so pretty are destined to be an algae infested nightmares that will crash and burn within weeks.
<Understood.>
I want to break down my 29 gallon and give it to her to do whatever strikes her fancy with, but I also want to make sure that her first fish don't end up floating... the tank she has picked out has a really interesting concept, and I can see how it would catch her interest, the photos are very striking, it is titled "crystal cave" and features an assortment of geodes, crystals, and broken glass tumbled smooth as the substrate.
<Hmm... no, in the long term these tanks don't work. A bright purple geode now looks like a green-brown lump after a few months. The sharp edges are terrible for bottom dwelling fish, and unless you're a skilled geologist, oddball rocks can be a potential source of dangerous metals like copper.>
I’m sure that properly done it could be a great system, but I am having a hard time figuring out how to maintain it and keep algae off of the crystals and the system in balance long term... I don't think she is going to be interested in snails (and at this point neither am I, due to the previous snail infestation issue... by the way, the DIY snail trap has been more successful in the past few days, I think I am starting to get the outbreak under control...)
<Good!>
and although I will sand all of the sharp edges I still don’t think this tank will be suitable for cories, otos or algae eating shrimp either.
<Indeed.>
as I said, I am probably going to use the 29 gallon planted tank, obviously the lights are going to have to devolve, as PC's on a non planted tank are going to give me pea soup...
<Not so. In dimly lit tanks, you get brown algae and to a lesser extent blue-green algae; in brightly lit tanks, the algae you get is green algae. Brown and blue-green algae is difficult to control biologically, but lots of animals eat green algae, so it's much easier to keep in check using shrimps, Nerite snails (which don't breed in tanks), Otocinclus, etc.>
I am thinking of using only LED "moonlights" which I think may have an interesting effect on the crystals, any idea of how fish will react to only LED illumination? should I throw in a really low output t12 for a more traditional light cycle?
<Fish don't generally care either way about lighting. Most prefer shady conditions if given the choice, but adapt to the relatively bright lighting in some aquaria easily. In other words, do what you want. Within reason, the fish will be fine, particularly if there are shady areas for them to hide in should they want.>
Also I will probably continue to use the Penguin BioWheel 330 that is on the tank know, I know it is way overkill for a 29 gallon, but if the system is going to be "un-planted" I think its going to be necessary.
<Not a problem.>
she has taken a liking to Angels and Gouramis, and if we stocked 1 pair of one of these how many other smaller fish (maybe cardinals, glowlights, rasboras, etc.) would be safe in a system like this?
<Angels can/do view small fish the size of Neons as food, so choose tankmates with care.>
also any ideas for algae control besides regular water changes? (I already do 10-15 gallons weekly)
<Plants are the only algae control that works. Everything else boils down to some sort of manual control.>
I'd appreciate any advise that you might have on keeping non planted systems stable, honestly I got into the hobby skipping the usual first steps of fake plants, pink gravel, and burping clams and dove right into planted tanks, so I have no practical experience with these kind of systems, hopefully I can get her interest into planted tanks soon, but for know this is a good first step!
<Un-planted tanks are easy, and present few problems. The main thing is to ensure what you use a decor is explicitly aquarium-safe. While there's nothing to stop you raiding a garden centre for interesting rocks and substrates, you do need to make sure said materials are safe. Rather than geodes and fossils, which are a waste in the long term, going with attractive and demonstrably safe rocks is a much better way forward. Pink and silver granite, for example, looks spectacular in aquaria, and is completely safe. It also helps to choose colours sensibly; light-coloured gravels, or funky blue or red gravels, tend to make the fish *less* colourful. Fish adjust their colours to their surroundings. The best colours are almost always where the sand is black or brown. If you want bright sand and colourful rocks -- keep a rock garden! But if you want your fish to look nice, choose natural-looking rocks and sand, so the fish settle in better. One book I might recommend is called "The Complete Aquarium" by Peter Scott. I mention this book because it has a similar format to the one you have, but the tanks are *much* more carefully thought out, and all are based on some sort of biotope. As well as freshwater set-ups there are nice brackish and marine ones too. Anyway, the reason I mention this book is that at Amazon it's going for the princely sum of $2.46, so won't break the bank! I think as a supplement to what your g/f is trying to do, you'll find it a good read.>
Thanks,
Bryan
<Hope this helps, Neale>

Re: Non Planted FW aquarium. – 11/20/07
Hi Neale!
<Bryan,>
I took your advice and ordered "the complete aquarium" and man was it $2.50 well spent! I also picked up a few other books for a buck each and now I have a pretty decent little library for under 20 bucks! I am going to be trolling Amazon from now on when it comes time to buy a new book, thanks again for pointing me in the right direction!
<It's a neat book. Slightly old-fashioned, but the aquaria demonstrated are wonderfully done and very inspirational.>
Anyway, the girlfriend has been fully bitten now... which is a good news bad/news situation... good news is she is getting into planted tanks, bad news: she likes oddballs... puffers, four-eyed fish, crabs... and paludariums. I’ve been itching to try a paludarium for a while so this is a good thing, but the only tank I have available for use is a 29G standard... which no matter which way I try to slice it I cant figure out how to get more than about 10-12 gallons of water into a paludarium setup, and I am not looking forward to trying to keep 10 gallons of brackish water stable... anyway she thinks the little "red clawed Thai crabs" in 'Aquarium Style' are cute.
<That tank would be fine for a small paludarium, especially if you used a lot of wood to create the above-the-water scenery. There is a small species of mudskipper on sale, nominally referred to as Periophthalmus novemradiatus but this identity is uncertain. It usually goes by the name of Indian or Dwarf Mudskipper. Maximum size is around 10 cm, though 5-6 cm is typical in aquaria. It has a reddish dorsal fin rather than blue, but is very pretty and not too aggressive. Mudskippers work best either singly or in large groups, where numbers prevents too much damage through fighting. In any case, these fish do supremely well in aquaria, and far better than things like the West African Mudskipper, Periophthalmus barbarus, a singularly nasty and aggressive (as well as big) species that was the most common species in the trade hitherto.>
I have no idea what they are and the only guesses I can make are (1) they probably prefer brackish water, and (2) they will probably eat anything they can catch...
<Yes and yes. They are Perisesarma bidens. Relatively easy to keep, and some hobbyists have even bred them! Not to be mixed with fish for precisely the reasons you give. Although not fish-eaters in the wild (like most land crabs they eat fruit and detritus) in the confines of an aquarium, sooner or later they nip and/or kill small fish kept with them.>
I doubt that I will be able to keep much with them in a freshwater tank... (if they’ll even survive in a FW tank) in a brackish setup what could I keep with them?
<Nothing. Enjoy them for what they are: entertaining little critters! By all means add brackish water snails if you want. Things like Nerites do a reasonable job of algae-control, and Malayan livebearing snails make ideal salt-tolerant scavengers that keep sand spotlessly clean.>
Puffers should be able to look out for themselves and four-eyed fish occupy a different niche so they would probably be ok right?
<No and no. Puffers will simply take the crabs apart if they are big enough, and if they are too small, the crabs could catch the puffers. Anableps need a peculiar sort of tank all their own. Basically a long tank, half-filled with water, with a "table" in the middle onto which they can rest with their eyes poking out. In anything else, their longevity tends to be unimpressive, and they usually fare poorly mixed with other species except maybe things like Mollies and Guppies.>
What about dragon gobies and/or mollies?
<I wouldn't mix any fish with red-claw crabs. Fiddler crabs are often fine with fish, since they're almost pure detritus feeders and have little instinct to catch prey. But red-claws are opportunists and will have a go at anything.>
And if I go with FW what about land hermit crabs? Are they a danger to fish and is there a danger to them drowning in a paludarium?
<Can work very well in paludaria, but terrestrial hermit crabs easily drown. They would need a tank with a very gentle slope so they could crawl in and out of the water easily. Not all species are brackish water animals. Also, they are 99% terrestrial, and only bathe to moisten their gills and to breed. For a generic brackish water aquarium, two fully-aquatic hermits are better choices: between SG 1.010 and marine, go with the commonly-sold reef hermit Clibanarius tricolor, and below SG 1.010 Clibanarius africanus works well. Neither of these poses much threat to fish, and both are hardy. Clibanarius africanus is, unfortunately, rather rare. Clibanarius tricolor on the other hand is cheap and easy to find (sold as the "blue-legged hermit" to marine aquarists) and does well in mid to high salinity systems with monos, scats, etc.>
I am trying to find a way to incorporate something different (and no matter how hard I try she just doesn't think cardonica shrimp are interesting...) but still keep a stable ecosystem,
<Amano shrimps aren't my thing, but there are some great alternatives. Cherry shrimps are lovely because they breed so readily, and will turn any aquarium into a veritable reef tank given the chance, literally crawling with shrimps of all sizes. Long-arm shrimps are also amazing animals. These are Macrobrachium spp., and a variety of species are now traded. Macrobrachium rosenbergii is the best/worst depending on your point of view; at about 15 cm in body length but with claws that are at least as long again, this is seriously impressive animal that will make hardened cichlid keepers break down and weep. It is also fun to watch and can be easily hand-trained. On the flip side, it is territorial and a confirmed fish-eater in aquaria. There are, thankfully, many smaller species such as Macrobrachium sp. "Rusty" and Macrobrachium "Red Claw" that are smaller and easier to keep. Some will form stable harems (one male, multiple females) and breed readily in the aquarium. They can be easily sexed: males have bigger claws, often with coloured bands on them.>
an oddball brackish tank is very intriguing to me, maybe 2 four-eyed fish, 1 small puffer, 1 dragon goby 3-5 crabs, maybe a trio of same sex mollies? This is likely too much for 10-12 gallons of brackish water right?
<Yes, too much and the wrong stuff.>
If I do go with a FW setup are there any land dwellers you could suggest that would fit in with your more standard aquarium fare?
<Nothing commonly traded. The problem for fishkeepers is that the bulk of freshwater invertebrates are insects, and these don't make good pets for a variety of reasons. Brackish water habitats are the prime places to see amphibious fish and crustaceans, and to some extent molluscs as well.>
She likes Killies, Gouramis, and the more colorful Cory's too, so we could probably put together a FW setup she likes, I'm up for pretty much anything, and if I had the space I’d have about a dozen tanks and I would be trying everything I’ve mentioned above, I’m just looking for a nudge in the right direction considering the set-up I have to work with and the critters that are grabbing her attention.
<Hmm... if she likes "critters", then arguably a marine system is the best option. If you forego light-sensitive things like corals, and don't keep any fish, maintaining a basic live rock plus shrimps, snails and small echinoderms tank isn't all that hard or expensive. In terms of brackish water, fiddler crabs and Mudskippers are a classic combo, though not without some amount of work to get right. Amphibious crabs can be superb pets, but in my opinion they are best kept alone.>
Thanks again for all the help!

<Cheers, Neale.>

Re: Non Planted FW aquarium. 11/30/07
Hi Neale,
<Bryan,>
Well the tank is done, it turned out great (I'll send a picture as soon as the water is in it and the plants are planted) I picked up a lot of 20 Red Mangroves off of EBay, it only cost 15 bucks including shipping!
<A sweet deal! Do read Anthony Calfo's great primer on mangrove husbandry in aquaria, here -- http://www.wetwebmedia.com/mangrovetrees.htm .>
Anyway, it is time to add the water and get the tank cycling, the problem is I cant find any info on the Sg requirements of the fish I plan to keep: Dwarf Mudskippers, Endler's livebearers, and Fiddler Crabs. do you have a suggestion for a good happy medium of salinity for this group?
<Anything from SG 1.005 upwards to SG 1.015 will be fine.>
I am thinking of maybe adding some of the blue-legged hermit crabs that you said could tolerate 1.010 and up, would the mudskippers, fiddlers and Endler's do good in 1.012-1.015?
<Yep, they'll be fine. HOWEVER, Guppies need to be acclimated very carefully, especially "fancy" varieties (there's a scientific paper about how fancy guppies are less able to thrive in seawater than wild/feeder/cross-breed guppies -- a clue to the fact selecting for colours and finnage doesn't always benefit livestock in terms of physiology). If you can, set the tank to SG 1.005 first, introduce the livestock, and let it run for a few weeks at that. After a couple months, gradually raise the SG a bit at a time until you get to SG 1.010 after, say, two to three months. This will bring along the filter bacteria and the fish perfectly well. Mudskippers and Fiddler crabs can tolerant virtually instant salinity changes, but Guppies not so much and filter bacteria not at all. There's also some reports than mangroves don't always like sudden salinity changes. Presumably this isn't the case in the wild, where mangroves surely experience salinity changes, but in captivity at least they don't like dramatic salinity changes.>
also, are there any corals that I could keep in that range of brackish water?
<Not really. If there are any corals that naturally inhabit mid salinity brackish water I'm not aware of them. The problem is that variable salinity environments tend to be silty, which is what corals don't like. Instead, brackish water habitats are the realm of scavengers able to process the vast amounts of organic detritus that wash out of rivers. So you have lots of bivalves, crabs, shrimps, polychaetes, etc. Lots of snails (Nerites, predominately) are in the trade if you can identify them properly. Someone wrote me recently that they obtained some brackish water ragworms, Namalycastis senegalensis, on eBay. Others have kept Actinia equina in high-end brackish systems but I suspect for long term care these need fairly high salinities. A store near my home has Asian mangrove horseshoe crabs, Carcinoscorpius rotundicauda, and these do very well in (large) mid-salinity systems provided they get enough to eat. So there is scope for adding inverts to brackish systems. Just not corals!>
Thanks again!
Bryan
<Cheers, Neale>

Freshwater tank set up.  10/11/07
Hello all.
I have tried to get an answer but have failed so far so am having to ask.
I have a 500ltr marine tank with about a 50 ltr sump. I want to convert back to freshwater and am wondering are sump tanks suitable for freshwater. All the previous freshwater tanks had canister filters.
<Yes, you can use a sump on a freshwater tank. One type of (advanced) freshwater aquarium uses the sump as a 'vegetable filter' by stocking it with fast-growing algae or plants to remove nitrogenous waste. Can work extremely well. But even as a plain sump, it adds volume to the tank and can be used to suspend things like bags of granulated peat, calcareous filtration material, or whatever.>
Are there any precautions I should take apart from fully flushing tank and components.
<No, it'll be fine. Even the trace salt left in the filter pump or wherever will be dilute so profoundly that it will have zero effect on water chemistry. Been there, done this.>
Can the live rock be used in a freshwater tank as have A LOT and don't want to scrap it or get a pittance from the LFS.
<Yes, live rock can be used, but obviously it will die. The dead stuff will contribute massively to the ammonia levels in the aquarium, at least for the first few months while it rots away. Some people have had marginal success with live rock in high-end brackish systems, finding that some of the crustaceans and worms adapted to the reduced salinity. But below SG 1.018, you can't realistically expect the live rock to remain alive. If I were you, I'd either trade the rock in or share with some other marine aquarist. It's just too valuable to reduce to mere aggregate in a freshwater tank, in my opinion.>
Any other tips gratefully received.
<A 500 litre tank is a wonderful canvas to work with, but do spend some time looking at the options. The freshwater side of fishkeeping is very diverse, and for the advanced hobbyist things like Tanganyikan cichlid communities or Blackwater stream communities can be challenging but very rewarding projects.>
Many thanks
Paul
<Good luck, Neale>

WetWebMedia can save lives, FW gen. set-up, cycling   7/19/07
Hello all
<Howdy>
Oh where to start, first, I must apologize for being an impulse buyer and not doing research before I purchased fish,
<A very large club indeed... to join, not to bonk you on the head with>
I got them from Wal-Mart sin #2)and knew nothing of cycling tanks or proper spacing for fish.
<You're obviously learning...>
Needless to say I have naively ended the life of some of my fish, but I am hoping to redeem myself; I have acquired a 35 gallon tank and trying to get it ready fast so I can end the suffering of my remaining fish the happy way. It is lit, heated, filtered, aerated, and currently housing 4 round-bellied mollies and a few fries
<Yummy with malt vinegar!>
born today, I am trying to cycle it properly but I am partially dyslexic and it is hard for me to do research
<... fight that gradient...>
so I figured I'd ask the pros. So here are it goes, is there a such thing as too much aeration?
<Mmm, can be... but practically speaking in a freshwater system, no>
In what way should I cycle a tank?
For how long should I cycle a tank before adding my poor fish? How do I test my water?
<Please read here: http://wetwebmedia.com/FWSubWebIndex/fwestcycling.htm
and the linked files above...>
What is the proper procedure for changing water from start to finish?
<Mmm, during cycling or regular water changes: http://wetwebmedia.com/FWSubWebIndex/fwh2ochgs.htm>
So far I have added some water from my existing tank to the new water which I filled and dechlorinated, it has been running for two and a half days so far. I think I read somewhere that when cycling you should change water frequently so I have done a 25% water change daily,
<Mmm, I would monitor aspects of nitrogen cycling (ammonia...) and NOT change this much water this frequently... see the above citation>
the mollies are doing fine but I don't think that means a lot.
<Au contraire... their apparent health is the best arbiter...>
I have not tested my water yet, per my question above. Thank you in advance for your help and once again please forgive me, for I was naive, not ignorant if I had known of my wrong-doings I would have acted differently. Sincerely Tom
<Press on Tom, and enjoy the process... You're doing better all the time. Bob Fenner>

10 Gallon Aquarium Setup  – 5/30/07
Hello!
<<Hi, Jess. Tom here.>>
I currently have a 10 gallon aquarium set up in my room for decorative purposes. I use a Top Fin BioFilter (meant for 10 gallon tanks), a heater (which isn't used during the summer since the water temperature stays a constant 73-74 degrees), and a floating thermometer. For decoration I have a small white (silk) plant and a Greek Column which hides the oxygen stone.
<<Sounds nice, Jess.>>
The tank itself has been up and running for about a month. I read somewhere that it takes about a month for the water in a tank to cycle through properly, so I originally had two mollies (silver and Dalmatian) to help get the needed bacteria and help the tank itself cycle through.
<<Jess, just FYI, using fish to cycle aquariums is pretty much “old school” thinking nowadays. There are faster and safer – for the fish – methods that can/should be used. Look into "fishless" cycling just for kicks.>>
I have given my two mollies to a close friend who is beginning a 20 gallon tank and after a week with no fish, I now have 2 Neon Sunburst Moons (Kiwi and Peaches) and 2 Jumbo Cardinal Tetras (The Twins). I was wondering what other types (and how many) fish I could put into the aquarium that wouldn't be too aggressive and maybe schooled since each of the species I have now tend to stick together and stay on opposite sides of the tank).
<<You could do worse than go with a few (three) of any of the Corydoras species. Great little fish and would fit nicely in your ten-gallon tank. They’ll occupy the bottom region, for the most part, which will be beneficial in a smaller tank. I wouldn’t go much further than this, though. Small aquariums can “get away from you” if you’re not careful. Best not to give in to the temptation to load your tank up. Just another piece of “useless” trivia now. Schooling among fish is a survival mechanism. Fish that “naturally” school may, and often do, stop the behavior in the absence of predators. (Just a little sidenote for you to tuck away for when you get a larger tank. :) )>>
My nitrite and ammonia levels are perfect and my pH has been a stable 7.0.
<<You’ve been testing! Well done!>>
(Sorry that was so long...just didn't want to leave out any details.)
<<I’m glad you didn’t and, thanks for that.>>
Also, I currently have a Betta Fish (Squiggles) in a 5 gallon tank. It is properly heated and filtered, with some live plants to help maintain the water quality. I was wondering, would the Betta feel uncomfortable in my unused 10 gallon tank by itself so I could use the 5 gallon tank as an emergency hospital tank? Or, would he be more than happy to move into a new and bigger home?
<<A ten-gallon tank would be just about spot-on perfect for your Betta, Jess, but I’d rather see you keep him in the five-gallon tank and use the ten-gallon tank for a hospital/quarantine tank. He’ll be just fine in a five-gallon aquarium and the larger tank would be better, in my opinion, for treating/quarantining fish should the need arise.>>
Thanks!
Jess
<<You’re doing well, Jess. Keep up the good work! Tom>>

Purchasing a Freshwater Aquarium with all the Necessary Components    5/15/07
Please Help!!!
<Is what we do>
I would like to purchase a 40 - 50 gal. aquarium along with the necessary components for my 10 and 7 year old kids (and myself) to enjoy.  We have agreed on the freshwater fish community, which will consist of  central and south American cichlids, African cichlids,
<Stop! Not a good idea to mix Cichlids from the old/new world in general>
angel fish, sharks and cats.
<Many choices....>
I have been to the chain pet stores and a few boutique stores in my area.  All are pushing different advice on the both the list of products that I need as well as the specs and manufacturers. I'm feeling overwhelmed. I do not want to get taken to the cleaners by over-buying as well as under buying the right equipment that will reduce the maintenance required.
Please help me understand the list of items and maybe manufacturers and ratings/specs on the equipment that I need to provide my family an enjoyable first aquarium experience. I don't mind paying for quality products that will work and last, I do not want to be oversold and by contrast, I'm suspicious of the quality and specs on some of the so called "kit or packaged" equipment that's being shoved my way.
<Most, well, all of this I would avoid... for reasons you obviously know>
I don't want to buy inferior or underpowered products that will wind up costing me more in the long run.
Please help me if you can.
Sincerely,
Frustrated in the Tank

Getting Started, FW sys. ... Teach your children/parents well...   4/2/07
Hi,
<Hello.>
You must be tired been asked the same question over and over again, this will be different I feel. I have been badgered from my 3 children to get a fish tank, the thing is they want coral rocks and fish similar to those in the finding Nemo movie. The questions that immediately spring to mind are.
<Glen, please don't buy an aquarium because your children are badgering you to. Fish aren't ornaments and they aren't disposable. Children want things one day, and forget about them the next. Keeping animals is a responsibility. Talk it over with your children first: Will they clean the tank once a week? Will they medicate the fish if they get sick? Will they buy the food and other things needed to keep the tank healthy? If the answers to any of these are No, then buy them some pet rocks or something.>
* What size tank would be best?
<The bigger the tank, the easier it is to maintain. Personally, I'd recommend anyone starting with fish to buy a *freshwater* tank around 20-40 gallons in size.>
* What are the best and easiest fish to care for?
<Certainly not corals and anemonefish (which is what Nemo was). Goldfish aren't that easy, either. Reliable first fish include zebra danios, peppered or bronze catfish, x-ray tetras, and thick-lipped gouramis. While other fish are often sold to beginners, many of these have flaws. Blue gouramis can be territorial, dwarf gouramis are sickly, angelfish are big and sometimes aggressive, Neons tend to be disease-prone these days, guppies are flimsy, mollies do best in brackish water, etc.>
* Do you have a starters guide
<There are lots. Please visit the web site -- http://www.wetwebmedia.com/ -- and just browse through, particularly the Starting and Set Up guides.>
*  Is it best to run the tank without any fish for a period to clean the coral etc
<You're muddling up lots of concepts here. Yes, cycling a tank without fish is a good idea, but to mature the filter rather than clean anything. Please read over the site and when you're done, go buy a book, sit down, read, and then explain to the kids.>
Any info would be of great help, as you will have gathered I am in at the deep end, and they will not back down.
Please help
<Not for me to teach parenting skills, but surely if the kids want something, it's up to the parent to teach the responsibility that goes with having a pet. If a child breaks a toy, that's one thing, but if a child allows a fish to die through neglect, that's something else entirely. Fishkeeping is a great family hobby, and a wonderful way to teach some basic biology as well as responsibility. But it sounds to me like this is something the kids want, not you. How about playing turnaround here. Figure out what your skills and budget are, and then figure out which sorts of fish (if any) match that. Marines are difficult to keep, corals even more so, and marine aquaria are very expensive and time consuming to keep. Maybe visit your local marine aquarium shop (on a quiet day) and chat with the proprietor. Get an idea of what's involved. Yes, it's worth the investment -- a marine aquarium is amazing. But it isn't the ideal aquarium for everyone. For absolute beginners, keeping a freshwater community tank can be a cheaper and much more reliable option. Tiger barbs and clown loaches both have Nemo-like colours, and the barbs at least aren't difficult to keep (though fin nippers, so choose tank mates with care).>

Just Starting Out 1/17/07
Hello,
<Hi>
Your website is amazing, and very helpful. I think (I'm sure you've heard this a lot) that almost everything the pet store told me has been wrong. <Sadly experienced this myself.>
My kids wanted to get tropical fish, so they each have a ten gallon aquarium set up in their rooms now. <Nice, great learning experience for them.> We set up the aquariums, (tap water that was conditioned with the stuff that's supposed to neutralize chemicals and aquarium salt in the water) and then waited 24 hours at the advice of the pet store, and then got starter fish for the aquariums. <Better than same day purchases I see so often.>
My son's aquarium:
My son wanted Molly fish, and the pet store said they were hardy enough so we got a male and a female molly. Also we got a Chinese algae eater, <May be problematic, several fish fall under this name, some being quite problematic.> also at the advice of the pet store. I am now reading that we probably should have gotten two female mollies, the male is already bugging the female a lot. She is starting to hold her fins tightly to her body, I'm guessing this is stress? <Most likely.> So what is better; getting a couple more females for an un-cycled tank? Or letting her stress for a few weeks? The fish seem to be doing really well other than that, and we are keeping a close eye on the water. <Good, I would not add more fish until the cycle is complete.  Make sure there are lots of hiding spots and plants/decorations to break up sight lines, may help her situation.>
Also, the next day the pet store advised us to put algae wafers in one at a time for the Chinese algae eater. They told me originally that the fish would eat the flakes until the algae grew in the tank, but then they said he wouldn't. So we are now putting a wafer in, one at a time, so the little guy has some food. <Probably not needed if he is eating other foods.  If not maybe every 2-3 days add one, but watch the water quality as this large amount of food can cause fouling quickly.>  Unfortunately, the male Molly (his name is Bob) <Appropriate name> keeps eating the algae wafers and chasing the other fish away. Is there any alternative to make sure he gets his food? Or should I not worry? He (Chinese algae eater) seems to have a ton of energy. <Would not worry yet.>
My son eventually wants to get some Mickey Mouse platies too, and I am now thinking, with a recommended 4 to 1 female to male ratio of Mollies, will there be any more room in a ten gallon tank? Is the same ratio advised for Platies? <If you did a 3 to 1 ratio for each may work, but reading about Bob's behavior makes me think he may not accept any other male live bearers in the tank.  Some male livebearers can be real little @#$$%s.  Maybe just female platies.>
My daughter's aquarium:
She wanted Platies, and again we were advised by the pet store that a male and a female would be a good idea. We brought home a Chinese algae eater, same as my sons tank, and a male and female platy. They all seemed to be doing really well all day. Then in the morning, the male platy was "not right." He was swimming weird, drifting with currents, and laying about. He was dead by lunch time. Poor thing! <Unfortunate.> But the other fish in the aquarium were doing just fine. I took him to the pet store, and they gave me a new male. I had my daughter pick one out of a different tank, because the fish in the tank that the first one had come from had fuzzy white spots on them. <Good though, although in reality both tanks probably infected due to shared filtration system.> Could that be ick? <Maybe, check out the pics and descriptions on WetWeb to diagnose.> Did I just bring that home to my aquarium? I hope the female doesn't start showing this. So now I am back to two platies and one Chinese algae eater. The platies seem to eat the algae wafers, the Chinese algae eater doesn't seem interested in it. Again, should I be worried? Is there an alternative food for the algae eater? This one also has tons of energy. <Best to leave for now, observe and act if a problem arises.>
The platies ate their food well in the morning, and really went after the very few bloodworms we gave them in the afternoon, but hardly touched their dinner. <Probably just not hungry, would feed once a day for the first few weeks.> The water now seems a bit cloudy on the white side, and so I did a 20% water change this evening. <When in doubt do a water change.> Is that a sign of bacteria from the food being left untouched? <Most likely.> Or is that just the food? The fish are very quiet this evening, and they seem to be hanging out by the heater. Is that stress or just normal? <May be due to the water quality. Test for ammonia and nitrite and do a water change.  Fish shop should be able to do these for you, but can be done easily yourself and a good chance to teach the kids a bit.>
My daughter would like to add neon and cardinal tetras to her tank after it cycles, will they get along OK with the platies? <Not really, Neons are quite difficult and both require very different water parameters than the platies.>  Also, do you recommend more females to males as you do with mollies? Same thing, minimum 4 to 1 females to males? <4 to 1 would be great, but 3 to 1 fine too.>
And how long do you recommend that a tank cycles before adding more fish? <Takes a couple of weeks normally, best to learn how to use the test kits and do it yourself.  Don't rush and all will work out.>
The pet store said a couple of days, I'm sure that's not right.
<Unfortunately you are correct.>
Thank you so much!
Mary
<Not sure if you have seen this yet  http://www.wetwebmedia.com/FWSubWebIndex/fwestcycling.htm but give it a read.  Don't let the charts and graphs scare you, its pretty straight forward once you get the concepts.  Good luck with the new tanks and welcome to a wonderful hobby.>
<Chris>

Just Starting Out Part II 1/17/07
One more thing to ask. <Sure>  Is it possible to have tetras and platies in the same tank? What type of tetras would you recommend adding to the platies? <Can't think of any that share similar water requirement.  Generally the species come from fairly opposite types of water.> And is there anything else that would be advisable to keep everyone calm and happy?  <Good water quality, good food, and everything should be ok, just be ready to deal with livebearer fry, they can and do put rabbits to shame.>
And thank you for the link to the "cycling" area of your site. I will go and buy some real plants for the aquarium as well as some algae starting products. I'll write it all down before I go as to avoid more bad advice!
<Good plan.>
Thanks so much!
Best,
Mary

Fourth try... Brand new used tank setup questions!   1/6/07
Hello all!
<<Hello, Audrey. Tom with you…finally, it appears.>>
Well, this is the fourth time I try to ask questions... first time was a couple days before Christmas... either my messages have gotten lost in the mail, or Christmas has made it impossible for volunteers to keep up with this incredible work. Just in case your server has problems with Gmail, I'm writing through Hotmail... never know what mysterious illness might ail your server!
<<Isn’t that the truth!>>
So... here it is again! Hi to whomever of the wonderful WWM crew might end up answering this one! I'm hailing from the French-speaking part of (supposedly cold, but it's been Spring since before Christmas) Canada (more precisely Montreal, Quebec), so I apologize in advance if my English is not quite as natural as it could be.
<<Well, Audrey, Detroit hasn’t exactly been a Winter Wonderland this season, either. We had temperatures in the range of 54 F. yesterday. You might well be getting these temp’s. today. Also, I'll guarantee your English is far better than my French. :)>>
My boyfriend and I are setting up our first FW aquarium. Of course, we've made a lot of progress since I first wrote, because we had all Christmas break to fiddle with it. We now have cleaned and set up the used 10gal we received from a friend who was going to throw it out. We put fine gravel in the bottom, a branch, some rocks, two Anubias nana, a couple of sprigs of Bacopa (guy at the store had two different batches of what looked like the same thing, a new (smaller plants) and an old one (bigger plants) and he didn't know if they were all the "dwarf" variety), and some bunches of Pigmy Chain Sword (those are growing very nicely already). We bought a neon that fit in the old hood and got rid of the Incandescents. We didn't treat the water since it's not really necessary for the plants, but we'll be treating with Nutrafin AquaPlus next time. This is the one product I was able to find locally that treats both Chlorine and Chloramines and doesn't look like it has 200 things added in. Should I mail-order something better or will this be sufficient? We did put some plant fertilizer in the water though. They told us that, since we don't have red plants, we didn't need a special iron
fertilizer. Is that true?
<<The AquaPlus product will do fine and I’m glad you selected a conditioner that treats both chlorine and chloramines. I agree that iron supplementation shouldn’t be necessary with the plants you have.>>
We put some hairy filter media in the filter to sift through the particles for the first few days (AquaClear Mini, rated for a 20 gal so I hope it's enough).
<<The Mini should do well for this size tank, Audrey. I’m using an AquaClear 50 on a 20-gallon tank and an AquaClear 70 as a second filter on a larger aquarium. I’m completely satisfied with both.>>
Water is a little yellow (I'm guessing from the branch) but we know this will clear up with time.
<<Yes.>>
We now have the proper sponge and carbon, and I managed to find a Bio-Max filter bag (the little ceramic things that are supposed to help with the bio-filtration - do they really work or should I still think of getting something with a bio-wheel somewhere down the road?)
<<The ceramic media works. When I clean the filter, I only rinse the sponge or the ceramic media, not both. I feel this ensures that plenty of beneficial bacteria remain in the filter chamber to do the job. The bio-wheel style filters are also excellent units. Can be a little noisy, though, if water levels aren't kept high enough. Otherwise, these are fine products that do the job very well.>>
We had to get a new heater because the one we were given would hold the water nicely at 73F but would quickly get it up to 80 as soon as I tried to set it a little higher - like it just wouldn't click off unless we fiddled with it.
<<Of the equipment we generally find in FW aquaria, heaters are the most problematic. Eheim has taken over production of the Ebo-Jaeger line of heaters and I love them. I mentioned recently in another post that the temperature dial can be “calibrated” to the exact water temperature in the tank and subsequent changes in the settings from there are right on the money.>>
It will be sufficient to prepare changing water though. The new one has been holding a nice steady 75 for two days now, and I'm going to be testing it a little higher this weekend.
<<Sounds good.>>
We got a great deal on the Aquarium Pharmaceuticals Master Kit. pH is around 7.8 right out of the tap but more around 7.4-7.6 in the tank (colour is hard to read on the pH test). Of course, nitrites and nitrates are 0, both from tap and in the aquarium, and also 0 ammonia from the tap. The tank has been set up for about a week with only plants and I'm already detecting about .75 ammonia! I didn't think I'd be reading this high with only plants!
<<A couple of notes on this, Audrey. First, an aquarium will cycle, ultimately, with nothing in it so your reading isn’t too big of a surprise. Second, and possibly more important, this kit – as will most – measures ‘total’ ammonia. That is, it measures both toxic ammonia (NH3) and less toxic ammonium (NH4). You can find charts on the Internet that allow you to calculate the quantities of both based on pH and temperature along, of course, with your ammonia reading. In this case, pH plays the larger role as ammonia converts to ammonium at lower pH levels. At this stage, since there are no fish involved, it really isn’t much of an issue but, I mention it just for clarity. There are more sophisticated test kits that measure for these compounds individually but I certainly wouldn’t be concerned about this now.>>
Do we need hardness/alkalinity tests? The employee we happened to talk to at the store (not their regular crew since we went during Christmas break) gave me a pH reading when I asked for alkalinity and didn't seem to get it when I told him it wasn't the same thing. I can't  blame him, I'm not sure I fully understand this yet.
<<As a general rule, I would not suggest these tests for the average FW aquarist. Not that I recommend against them by any means. They just aren’t as useful to us as they would be to our saltwater counterparts. There are exceptions, naturally. Those people running African Cichlid tanks, for example, where higher pH levels are important would likely be interested in these tests. As you mentioned, though, the relationship between pH, alkalinity and hardness can soon start to resemble a display of “semantic gymnastics” if a clear understanding of each just doesn’t want to “sink in”.>>
He did tell me though that their water has hardness around 9 (does that make sense??), he told me it was average. We live 3 blocks from them so I think we can safely assume our water is at least very similar.
<<8-12 degrees dH is average (German degrees hardness scale) and this is the scale commonly used in the hobby so, yes, it makes sense.>>
The water is not quite as clear as it was a few days ago, but nothing's really happening in there either - yet. We're thinking of adding a raw shrimp to get the ammonia to spike, since we'd rather wait for the plants to be well established before we add fish anyway.
<<Excellent. The shrimp will help speed things along, by the way, as will common fish food for that matter.>>
At the rate the ammonia is climbing presently, we'll have to wait months before we can add anything! No, we can't get Bio-Spira locally, it's not exported to Canada because of some funky regulation about live bacteria.
<<Some countries are “touchy” about such things. :)>>
The only thing we can get is Hagen Cycle (unrefrigerated)  which, from what I've heard, is mostly useless and a waste of money - unless it has improved dramatically since those opinions were posted on WWM?
<<Think of it this way, Audrey. If Canada won’t allow BIO-Spira because of live bacteria but will allow Cycle, I think you can put two and two together. ;) >>
We haven't changed the water yet, of course, but when we do, I'm wondering how we have to proceed. We have fine gravel (1-2mm size) so I'm afraid that if we use the vacuum, we'll end up taking the gravel into the bucket. Also, we can't really disturb the plants. Is holding the siphon end right above the gravel sufficient cleaning?
<<For now, yes. I have a similar substrate in one of my tanks and it’s a pain in the backside (if you’ll pardon the expression) to vacuum but, with practice, it doesn’t completely pull in as much of the gravel as you might think. A few pieces here and there but a necessary consequence if you want to avoid dangerous build-ups of mulm/detritus.>>
We originally wanted to start with goldfish, but after reading your site I decided it might not be the best idea :-)
<<Good decision. A ten-gallon tank is too small for even the smallest varieties and more than one would be way too many fish.>>
What I really want, of course, are dwarf puffers and a yellow tang, but that will wait until we feel like we know what we're doing - especially for the saltwater  fish (that looks like a whole complex universe in itself). So now, we're looking into Mollies and a Betta. I've heard they can go together (same temperature, for one thing).
<<Mollies are a brackish species that “might” acclimate to salt levels that a Betta would appreciate, about one tablespoon per five gallons. My concern for you here is if the Mollies get ‘fin-nippy’ with the Betta. Shouldn’t, but one never knows.>>
Now, this is only a 10 gal and I don't want them to get too crammed, I was wondering if 4 Mollies and a Betta would be too many for a 10 gal?
<<There are Molly breeds that tend to stay small, say around two inches or so. There are others that can reach five inches. Obviously, the larger varieties would need to be avoided with your stocking scheme. Common sense and judicious selection will be the order of the day.>>
The reason I'm thinking 4 is that I'd like to have 3 females and 1 male. I've read that having 2 females sometimes doesn't work too well for Mollies, because the male tires them too much. I'd really like them to have babies, even though I'm also looking forward to the Betta being natural population control, but if that's really too many fish I'll consider getting 3 females only.
<<Your thinking on the Molly ratio is quite correct. Another consideration is that a female, after giving birth, really needs to be isolated until she recovers from the ‘blessed event’. Hardly an insurmountable problem but something that I thought I’d mention.>>
I know Mollies are usually considered brackish and can even be kept in full salt water. I've also read strong opinions to the contrary. I've also heard people recommending that we add 1 tbsp of salt per 5 or 10 gallons of water for Bettas. Is that something that could be beneficial to both fish? If so, do we need to get a hydrometer? Is there one that would read that low?
<<Salt is absolutely beneficial to both species. No question about this whatsoever. The trick, if you will, is finding a common ground and I believe that one tablespoon per five gallons will work.>>
Temperature-wise, I think we can keep it 78-80F. Is 80F too hot for Mollies?
<<Should be just about right, Audrey.>>
Also, I'd like to have a few shrimp. I know Ghost shrimp will eat leftover fish food, and either Amano or Cherry will eat algae also. Can we mix shrimp species? Will they provide enough algae control? When we siphon water, how do we do it as to not siphon the shrimp? Those things are *tiny* at first...
<<The shrimp you mention can be mixed with one another. As for algae control, this will largely depend on how you maintain the tank. Lighting and excess nutrients will determine, in large part, how much algae growth you’ll have. By the same token, your plants may out-compete the algae leaving you with little or none growing. Some variables involved on this one. As for siphoning, you might try attaching a piece of coarse mesh over the end of the vacuum tube. Something that will allow ample room for the removal of the funky stuff without giving your shrimp an unwanted ride.>>
The local store has absolutely gorgeous golden apple snails. I know they're separately sexed, and I've read that if I quarantine him for about 2 months I'll be certain not to have hundreds of incrementally increasing offspring. (I'll be really happy to exponentially breed snails IF and WHEN I finally decide to keep puffers, but until then, I'd rather go low-maintenance... :-) I've read some people say they eat plants, others they don't seem to bother them... what's your experience with this?
<<Personally, I confess to no experience with Apple Snails, Audrey. What I can share with you is that snails, generally speaking, go after the dead or dying foliage on plants leading to the perception that it’s they who are responsible for plant damage. In this case, they’re getting a bum rap.>>
In any case, I was thinking of adding the Mollies first, than the shrimp and/or snail, and then the Betta. I was thinking that, since he seems to be the most aggressive of the lot, he should go in last, so he doesn't already "own" the tank when we try to introduce tankmates - does that make sense or am I totally off base? Should I keep him separated at first so he can get used to his tankmates before releasing him or does that make no difference at all?
<<I don’t know that with the Mollies, potentially, outnumbering the Betta 4:1 that the order of introduction is particularly important. I do, however, believe your rationale to be quite sound.>>
Well, I think that's about it. We're brand new at this and will yet have many questions... In the meantime, please let me know if you have any suggestions to improve this setup. Nothing's started yet so this is the perfect time to change plans if we need to :-) I'm now going to go ahead and read some more on your site... You have info there for WEEKS of reading :-)
<<It sounds to me like both of you have an excellent feel for what’s needed as well as what’s going on. Please do continue to read/research on the site and welcome to our wonderful hobby!>>
Thank you so much,
Audrey

Re (Tom) : Fourth try... Brand new used tank setup questions!  1/10/07
Hi again!
<<Hi, Audrey. Tom again.>>
Tom answered my last question.
<<Did I get it right? :)>>
Wow, guys, you DO have weird mail server problems... I saw the answer posted on the FAQ but never received it in my mailbox (and I did check my junk mail too). And I answered the answer, but it seems you never got it... so... I'm trying again (and again, and again, and again... ;-P
<<There’s a guy in Ontario that “vacuums” space for all e-mails going to Quebec, Audrey. The OPP is working on it. (Now I’ve got two dozen people wondering if this is true and what, in the world, “OPP” stands for. “Ontario Provincial Police” and, I’m kidding about the guy…maybe. :)>>
In any case, thank you so much for the answer. It's very reassuring to know that we're on the right track with this! I'd rather not have to fix too many avoidable problems after the fact...
<<Or any, for that matter.>>

We bought an Italian brand that our LFS assured us was as good as the Eheim, only not as well-known. Apparently, he's been using them for years and is extremely happy with them. It's shorter than the Eheim.
<<Drop us a line with the name of the heater and/or company. We’re certainly open to making recommendations to folks.>>
About the calibration trick, I tried searching the WWM site but couldn't find it. And I didn't find it in the dailies either. Do you have any idea where it's been archived?
<<Not really a trick, Audrey. There’s a locking pin on the dial that can be released to allow the knurled knob to “freewheel”. The knob can then be repositioned to the exact temperature of the tank and the pin is then locked back into position. Subsequent changes in the dial setting are then guaranteed to be within 0.5 degrees +/-.>>

Good to know! I might look up the charts, just for the "learning experience", even if it's really overkill at this point :-)
<<Handy to know if problems should arise. Sadly, in some cases, illnesses that might have been treated successfully aren’t, frequently due to valuable time being lost trying to remedy a problem that doesn’t, for all practical purposes, even exist. A good example, though out of this specific context, is when Columnaris – a serious bacterial infection – is treated as a fungal infection. The fish is incorrectly treated, doesn’t respond (for obvious reasons) and, ultimately, succumbs to a condition that was curable.>>
(Quote)<<Think of it this way, Audrey. If Canada won't allow BIO-Spira because of live bacteria but will allow Cycle, I think you can put two and two together. ;) >>(/Quote)
Hmm... good point!
(Quote)<< Personally, I confess to no experience with Apple Snails, Audrey.>>(/Quote)
I did a little more reading. Apparently, there are several very similar
varieties of Apple snails, some of which will eat plants and some who won't (much). But the main problem here is that they grow very big and would have to count towards the total bio-load... I can add many many shrimp before even coming close to what the snail  would represent... soo... shrimp it will be!

Re (Tom) : Fourth try... Brand new used tank setup questions!   1/11/07

Bonjour Tom!
<<Bonjour, Audrey.>>
It's me again! I've been totally obsessing over this aquarium thing. Three weeks ago, I didn't know *anything* about aquariums. I must have spent a few hundred hours reading (mostly on WWM, but I have a few books on the subject as well).
<<No lack of information out there/here, that’s for sure!>>
I really envy Bob right now (I read he's in Hawaii).
<<It’s occasionally hard to keep track of Bob but I believe you’re right.>>
What really got me interested in fishkeeping is a trip to Hawaii two years ago (Big Island). Literally hundreds of yellow tangs grazing right below our hotel. And this really neat beach just south of Kona, we'd do our half hour of snorkeling every morning, just floating through the fish. Ahh... any of you ever been to Goldfish Market in Hong Kong? It's *amazing*. It's like putting 50 nice fish stores all together on one street (well, nice-looking in any case... Dunno about the quality but the variety was certainly there... my parents were not really interested so I had to do my little tour rather quickly). And some NICE specimens too. I'd never seen cowfish so BIG!
<<I’m afraid it would be like turning a kid loose in a toy store for me! Must have been a wonderful, if short, tour that you had.>>
Well... I digress. Sorry. Back to our subject.
<<Okay…>>
I just found out that one of my local stores has Nutrafin Chlor X Change. That one is definitely labeled as treating only chlorine/chloramine/heavy metals. I've been using AquaPlus because that's the "best thing" I found, but it has additives. Would it be a good idea to switch once the bottle of AquaPlus is finished?
<<The AquaPlus neutralizes heavy metals, too, Audrey, as well as handling the chlorine and chloramine. Conditioners are, generally, pretty decent across the board so it’s pretty much of a coin toss.>>
You asked about my heater. It's a Hydor Theo.
<<Kind of exactly like the one I have for my 10-gallon quarantine tank? (Sometimes all of my cylinders aren’t firing properly, Audrey.)>>
My LFS recommended it, said it was comparable to the Eheim in quality and accuracy.
<<No complaints with mine, certainly.>>
So far it's been holding the temperature very nicely, varying *maybe* half a degree throughout the day. Well, for the past week at least :-) The only problem I have with it is that, at the lowest setting (which is supposed to be below 70), it holds the water at a nice constant 75.
<<Other factors perhaps?>>
The calibration's off but the heater is performing well. I'll see if I can adjust the dial by releasing the locking pin, like you suggested. Maybe that's the problem.
<<It’s the Ebo-Jaeger (Eheim) model that has the calibration pin, Audrey. The Hydor has what appears to be a pin in the center of the dial, as well, but I’ve found it doesn’t seem to do anything. Mine doesn’t anyway.>>
Well, enough for now. I'll send you a donation, you've saved me a lot of money and aggravation.
<<For Bob and the rest of the WWM crew, I thank you. It’s most kind and generous of you.>>
Merci encore!

Freshwater Beginnings, book recommendations  1/2/07
Hi,
<Hello and Happy New Year!>
I've got a 30 gallon tank that I've previously used for saltwater (until I got a bigger tank and better equipment) that I'd like to set up for a freshwater system.  I know most people start with fresh and work over to salt, but that's not the case with me- I'm a beginner for fresh (and not yet an expert with the salt).  I've looked over your FAQ's but would also like to purchase a book that I can lay in bed and read (hard to do with the computer). Do you have any recommendations?  I love Fenner's "Conscientious Marine Aquarist" book and would like to find something similar for freshwater... but I couldn't find anything by him or Paletta, another of the saltwater sources that I really liked,  that dealt with this topic.
<Welcome to the wonderful world of freshwater aquariums.  For the first time freshwater aquarium, I like to recommend David E. Boruchowitz's Simple Guide to Freshwater Aquariums - everything is very easy to read and understand, but I do think he tends to "push the envelope" a bit with his suggested stocking schemes (e.g., a bit overcrowded).  Other than that, it's a great book.  For an index of many sorts of freshwater species, I recently acquired Glen S. Axelrod & Brian M. Scott's Encyclopedia of Exotic Tropical Fishes.  As far as diseases go, I highly recommend Mary Bailey and Peter Burgess' Tropical Fishlopaedia.  Don't know if any of these rival Bob's SW book, but they are my personal favorites.  Good luck, and enjoy your new tank!

Thanks!

Starting my tank   12/19/06
Hello,
<<Hello, Tara. Tom here.>>
We have just bought the jewel tank containing 190 litres and are setting it up to contain red belly piranhas. We originally wanted 3 but after reading your site discovered that its only really big enough for 2 at a push.
<<Given an adult size of approximately 12 inches (30.5 cm), two of these fish would, indeed, be pushing the limit of a 190-liter (50-gallon) tank, Tara. Adequate cover and low lighting should be provided to keep “skittishness” to a minimum.>>
We also would like to know if it is essential to test the water pH before putting in the fish.
<<Do yourselves this favor, Tara. Visit the pet shop and find out what the pH is of the water that your future pets are currently being kept in. Piranhas come from waters that are soft and acidic in their natural habitat with the pH below neutral (7.0). This really isn’t as critical as trying to avoid introducing them to a tank that’s far off from what they’ve been acclimated to, however. Stability is the key factor here.>>
The tank has been set up for nearly 2 weeks now at the right temp and I don't want to be ignorant by hurting the fish by just putting them in without it being perfect.
<<pH is not going to be your only concern here. In fact, ammonia and nitrite levels are going to be far more of a concern right now than pH will be. Unless you’ve taken some extraordinary measures to speed up the “cycling” of the tank, I doubt that your tank is more than one-third to one-half through the cycling process after only two weeks. Test for ammonia and nitrite (both should be zero) and check your nitrate levels as well. Nitrates, by way of explanation, are the “end product” of the nitrifying process. If ammonia and nitrites are zero but nitrates are also zero, your tank isn’t ready for live fish. Your pet shop can test a sample for you if you don’t have a test kit already. Personally, I highly recommend that you get one so that you can do your own testing. Shops have a tendency to tell folks that levels are “safe” without being specific about what this really means. Better in the long run for you to know “exactly” what your readings are. More convenient, too.>>
Also, what would be your best recommendation to start feeding them as they are only about the size of a 2p when we get them.
<<Thawed mussels, prawns, shrimp and fish will be appreciated but there are processed foods, in the form of pellets, for carnivorous fish like Piranhas that they may also take to in order to vary their diet. You might find that early on they’ll also accept flake food. (By the way, ‘2p’, for the benefit of our American readers who don’t have one readily available, is about the size of a Susan B. Anthony dollar, which is nearly exactly the size of an American quarter. That one might have worked better if George Washington and Ms. Anthony hadn’t look so much alike. :) )>>
(Although, my husband really wants to feed them live food on occasion. I suppose it’s a bloke thing).
<<Advise your husband to keep this to a minimum, Tara. Feeder fish have little nutritional value and can be a source of disease. You and I know he’s going to do it anyway but, it’s not without risk to your pets.>>
Thanks for your help
Tara
<<Consider giving your tank another fortnight (I don’t get a chance to use that term very often) to cycle completely and really consider the test kit I mentioned. Uneaten food, if there is any with Piranhas, will need to be removed to prevent your water conditions from becoming toxic. Good idea to stay on top of this as best you can. Good luck with your new additions, Tara. Cheers. Tom>>

First fish, for a small FW system, young girl   9/26/06
I have read a bit  on your site and realized we have done very little  right.
<Each journey....>
I bought a 5 gallon tank for my dd's 8th birthday, hoping that a fish  would be an easy first pet for her.
<Can be...>
  I was planning to buy a couple  very small feeder fish for her to start with so when they died I'd only be out  20 cents.  
But she liked the big fantails and her daddy couldn't resist her  pleadings.  
So now 3 days later one is dead and buried in the backyard and  the other doesn't look so good.
So for our next try what kind of fish should we try for her.
<?>
She is motivated to care for the tank, but we need something simple.  We have a 5  gallon plastic tank with and under-gravel filter, an air pump and a couple of  plastic decorations--and a  little girl who is very sad that her dear fish  died already.
Thank you for your help,
Becky
<Do you have a heater? Do look into Paradisefish (Macropodus opercularis), or some small Danios (Like Zebras, Brachydanio rerio)... At this stage, very important (to me, you, your daughter) to find, secure a professional relationship with a LFS (livestock fish store) that you trust, feel confident with... to grant you this information, aid you in picking out initially healthy livestock for such a small system. Do please feel free to continue to seek our input as well. Bob Fenner>

Used tank , filters, stand  etc questions   9/17/06
First off let me thank you for your *fantastic* and informative site. I have spent only a couple hours browsing it and have already learned a lot. I've searched and read through the "used tanks" information as much as I could find, and found some info that's similar to our situation, but still have questions (and lots of insecurity!) We're fairly new to fishkeeping; have a 20 gallon tank with 6 goldfish (I know, I know, too small but read on!) and a tetra whisper3 power filter that's still cycling (we figured out too late that cycling is something tanks have to do... Poor fish.
<Do be careful re feeding...>
But we're trying. Lots of water changes. Think we see some nitrate showing on the test strip today... barely)
<Ahh, good>
We were given what I think is a 55 gallon glass tank (48" X 13" X 21" more or less) (using the formula I found here, was able to determine that it's 56.73 gallons, so I assume that's a 55 gallon tank),
<Yes... often called a "55 Show" in this configuration>
made in 1990 by "Patti" according to the tag on the frame <grin>, and all the stuff that goes along with it. The tank was used for both fresh and marine. We have cleaned it thoroughly with water, nothing else, scrubbed with a new "scrubby" to get as much of the water deposits off as we could.
<Vinegar (with air circulation) is safe here as well>
We filled it outside and let it sit for a week, now, so we're pretty sure it doesn't leak. (It was kept in a basement, suffered a flood and probably was "bombed" for bugs a couple times over the past ten years that it's sat empty)
Further "Stuff":
A Marineland Magnum 330 canister filter which appears to have only the water polishing filter, nothing for carbon filter etc. There are *two* of the bottom part, so I'm assuming he either had one as a back up or that one doesn't work.
<Or had another for switching out, cleaning... Quite common>
Is there a way to test this before trying to set up the tank, using a bucket of water or something?
<Yes... and/or can use the tank you're testing...>
It appears to be missing a piece that I think is the diffuser (where the water goes back into the tank), and I imagine it would be wise to replace all the tubing?
<Yes, can, and likely should... the vinyl tubing sold at Home Depot is useful here, as well as the same diameter likely available from a fish store... these units are still made, pretty much the same... By Marineland>
A Penn Plax XP 990 air pump and an under gravel filter set-up. At least, I think that's what it is--has a unit that plugs into a wall outlet, the air pump I guess, two plastic plates that fit across the tank's bottom and that have slits in them and V-shaped "bumps", each piece has two covered holes (covers can be taken off) and two holes that are open but have a "thingie" sticking out of them. I assume these are where air passes through as bubbles and are where we're supposed to plug in the   four clear hard plastic tubes that have an air diffuser inside attached to a tube, a "hood" at the top of each (Aims the upflowing bubbles downward into the tank?),
<Yes, good descriptions>
with the tubing coming out of them and passing through a "holder" that hangs on the back and that also has valves (4);
<Yep, an air gang valve>
from there a single tube going into the pump. These tubes would also, I assume, be better off replaced.
<Yes... airline tubing, 3/16" ID>
full-length light (have to look up what kind it is--has two fluorescent bulbs)
A particle-board cabinet (Matches the light's and the tank's "oak" (plastic laminate) frames)
<Do make sure this is still sturdy... the whole shebang will weigh more than 500 pounds...>
2 heaters (is there a safe way to test them?
<Yes... put in the tank (submerse all the way if they're sealed, hang on the side if there are means for such... leave be for about 15 minutes (to allow the thermostats to adjust) and plug in... turn the dials on top (clockwise to higher)... till the "lights come on"... indicating the heater is energized... and use your hand to sense whether the heating elements (toward the distal end) are indeed heating... Make sure and unplug, allow to cool down for at least 15 minutes before removing from the water (to prevent breakage)>
just stick em into a bucket, plug in, and see what they do?) One is for sure submersible, not sure about the other.
Plastic cover (in two pieces)
One "Topless Beach -->> " sign. <grin>
A whole lot of stones (large gravel) of a nice tan/white/sand color--will  give this a really good cleaning, unless it's not safe to reuse in a fresh water tank once it's been used in a marine tank?
<Just rinse, soak all>
Large chunk of lava rock Coral (Am leaving this out-- too sharp edged for our black moor's eyes)
<Yes... and likely the lava rock as well>
Some other kind of rock--tan and white, rough feeling, big "hidey hole" for fish...gorgeous for people to look at...--how can I find out what it is? Sandstone maybe?
<Likely so, and very likely safe chemically>
We feel as though we were given a treasure chest, here!!
