Getting
better 8/21/08
A quick word to thank you again for the incredible service you offer to the
community. I'm an almost-daily avid reader.
<Cool!>
I also wanted to share -- my plants are finally GROWING!!!
<That's nice to hear. What did you think you changed in the tank that helped?>
Thanks for all the FAQs and articles...
Audrey
<Good to hear from you. Cheers, Neale.>
Re: Getting
better 8/21/08
Well, since you're asking :-)
- I have a bigger tank (I had a 10 gal and switched it for a 20 gal) -
incidentally, I'm also using two Aqua-Clear Mini instead of one, since I think
using only one on a 20 gal tank is grossly insufficient, even if the
manufacturer claims it's enough. I kept the existing livestock (two Nerite
snails that have been with us for 18 months and a year, respectively - I have
yet to get fish after the Camallanus disaster of a few months ago, but I added
an Apple snail [most fascinating animal I've ever owned] who's munching somewhat
on the plants, but not enough to cause real damage).
<Ah, yes, some people do indeed have good luck with Pomacea spp. in planted
tanks. It does seem to vary on the species of snail and the type of plants, and
perhaps on what tastier foods the aquarist puts on offer.>
- I changed the substrate (I'm now using Fluorite, instead of gravel).
But what I suspect really made the difference:
- Better lighting! I was using the Life-Glo screw-in bulbs, I'm now using two
Coralife T5 - one 6700k and one full-spectrum.
<Yep! Makes all the difference. Plants are photosynthetic. The more light, the
more food they make. There's subtleties to this equation to be sure, but in
general upping the light can turn around a tank where plants have otherwise
failed.>
The BGA is regressing, and that's with plants that had been doing *nothing*
except slowly dissolving for weeks and have now been in better conditions for
about three and have just started growing - which means I'm starting with
unhealthy plants, and it's still having
an effect. We'll replace them with healthy plants soon - I expect the BGA to not
be a problem anymore. (I don't mind having some. I just mind when it covers
everything).
<BGA does tend to fade away once the environment is suitable for plants. You can
get BGA in tanks with plants, but rarely in tanks with good lighting and
healthy, fast-growing plants.>
We've tried many different plants, the only thing not dying was the Anubias. The
Bacopa, Vallisneria and Amazon Chain didn't survive our previous lighting. Now
we have African something (my boyfriend brought it home without a name, Grrrr! -
looks a little like mint) and Amazon Swords doing good - and the original
Anubias as well.
<Hmm... The African fern Bolbitis heudelotii perhaps? There aren't many
completely "African" plant genera in the trade (for whatever reason) apart from
Anubias and Bolbitis. There are African species of Aponogeton and Crinum though,
and lots of species include both Africa and Asia as their natural range, such as
various Vallisneria.>
I guess I can't say I couldn't have done it without you, because I could have,
but it wouldn't have been nearly as much fun!
<Heh!>
Thanks again!

<Glad we could help, Neale.>
Brown spots on plants, plants not growing -04/22/08
Hi Bob,
I have a five gallon eclipse system which has been established for about two
years. I recently moved to a planted tank and I have some small driftwood and a
white rock (which keeps the pH higher, but still within normal parameters 7.2)
My plants aren’t growing well at all! I’ve had them planted for about a month so
far. I’ve got brown spots and others have melted altogether. I have 2 watts per
gallon (new bulb a month ago) and I have them on a 10 hour daylight cycle. I
dose ˝ ml of Flourish, Excel and Iron five days a week (mon-Fri.). I was under
the impression that you can use regular coarse gravel and supplement if you have
enough light. Am I over fertilizing? I keep waiting for “new growth” but I’m not
getting any!
Thank you,
Shauna
<Shauna, there are several potential issues here. To start with, small tanks
need proportionally more light than big tanks for plants to grow well. The
science is a bit complex, but basically it works like this: while 2 gallons per
gallon is fine for low-light plants in big tanks, there's a minimum wattage you
need simply for the light to have enough "punch" to work. So while 10 watts over
a 5 gallon tank sounds fine in theory, in practise a 10 watt bulb may simply be
too weak to support plant life, period. Another issue is substrate: few plants
thrive in plain washed gravel, however much fertiliser you add to the water.
Things get even worse if there's an undergravel filter installed. Thirdly, you
don't say what the plants are. Be under no illusions about this: some aquarium
plants sold in stores are either not aquatic species at all, or simply very
difficult to maintain. I have a 10 gallon system with an 11 watt bulb, and plant
growth is remarkably good even though that's barely 1 watt per gallon. What's
the secret? Firstly a nutrient rich substrate, basically pond soil mixed with
silica sand, and then topped with a bit more silica sand to keep things clean.
Secondly the right plants: species that need little light to thrive.
Specifically, these are Anubias barteri, Java fern, Java moss, and Cryptocoryne
wendtii. These give you a lovely mix of plants in terms of colours and shapes.
Practically everything else in the trade needs much more light and will not work
in this sort of aquarium. All except the Cryptocoryne are attached to rocks and
wood rather than buried in the sand. The tank is also understocked, and this
helps to keep water quality good, another useful approach when maintaining small
tanks. Cheers, Neale.>Re: brown spots on plants, plants not
growing 4/22/08
Thank you Neale,
You're response is very helpful - I'll see about getting a retrofit for my
canopy and look into removing the substrate and starting over.
- Shauna
<Good luck, and enjoy your aquarium. Cheers, Neale.>

What to do with Toxic Gas Trapped in
Soil? – 09/19/07
Hi,
I wonder if you can help you. (You all seem really busy at WWM.) I did
search for the answer, but I only found that gas DOES get trapped in the
substrate, not what to do about it.
I have a 55 gallon planted tank that has been running for a year now,
with 5 year old angelfish (the mated pair is going into the 25 gallon
tank soon), 3 nickel sized angel fish (they're doing fine together), 11
neon tetras, 2 swordtails (both male), and a Pleco (5-6"). I have the
black EcoComplete substrate, which has worked fine for me.
However, I recently went in to replant a couple of the plants, moving
them from the end that gets about an hour of sunlight each morning to
the side that doesn't. When I lifted up the plant, the substrate was
fine, but when I stuck it into the other end of the tank, air bubbles
came out. I've read that this is an extremely bad sign, meaning that the
plants at the other end of the tank haven't really grown their roots,
and that there's some kind of nitrogen compound trapped in the
substrate. First of all, is this an emergency-immediate problem?
Secondly, is there a way to fix it without taking out the fish from tank
or harming the fish? (Can I just poke some holes in the substrate with
my finger to let the gas out or is that a big no-no?) And what's the
long term solution?
Should I switch out the 80W for more light? (The plants are all alive,
just not thriving, apparently.)
Thank you all for your time and effort and any help that you can
provide,
Nea
<Greetings. The "gas in the substrate" problem is wildly exaggerated
within the hobby. Here's the basics: Anaerobic decay can result in the
accumulation of a gas called hydrogen sulphide (H2S). In theory, because
this gas is toxic to fish, any bubbles of H2S can harm or kill your
fish. However, in practise H2S oxidises very rapidly, and once it is in
contact with oxygenated water the H2S gets converted to plain old
sulphur (or as the Americans spell it, sulfur). This reaction is so fast
that it is for all practical purposes instant, so small amounts of H2S
will be rendered harmless long before the concentration in the water
reaches dangerous levels. Marine aquarists have learned to embrace
anaerobic decay, and routinely set up filters (e.g., deep sand beds and
mounds of living rock) that perform anaerobic decay. I also have yet to
see a pond that *didn't* have masses of anaerobic decay going on in the
thick, gooey mud at the bottom of the pond. But for whatever reason,
freshwater aquarists are still skeptical. So let's put things into
perspective. Anaerobic (or at least dysaerobic) conditions are normal in
muddy freshwater substrates, and most plants actually prefer them to the
clean, oxygenated plain gravel substrates we usually give them. Under
anaerobic conditions the mineral ions they want are "reduced" and more
easily absorbed than they would in their "oxidized" states. Plant roots
carry oxygen into the substrate via a tissue called aerenchyma, which
you can think of as being a bit like a snorkel. Some of the oxygen
carried down to the roots escapes and immediately around the roots the
conditions are partially, but not completely, oxygenated (i.e.,
dysaerobic rather than anaerobic). So wherever plants are growing, the
actual risk of dangerous levels of H2S developing becomes even smaller.
Occasionally poking the substrate with a stick to stir things up a
little won't do any harm, and I always add Malayan livebearing snails to
planted tanks because they do this automatically, behaving rather like
earthworms do on land. In my view, these snails are indispensable and as
you probably know they never, ever harm plants. Now, this brings us to
the question of why your plants aren't growing. This is almost certainly
nothing to do with the substrate. Since you're using a proper
plant-growing medium, Eco Complete, and I hope to a reasonable depth
(not less than 8 cm, but no more than 12 cm without a heating cable), so
that aspect should be solid. No, the problem is almost certainly
lighting. For good plant growth you need at least 2 Watts per gallon.
You can get by with a bit less in shallow (<30 cm deep) tanks using
shade-tolerant species (like Java moss and Anubias) but in all other
cases the more light the better. In practical terms, you're aiming for
at least 4 tubes that run the length of the tank. Ideally, these should
be plant-friendly tubes with a "colour temperature" of around 6000
Kelvin, though to some extent plants will adapt. Fitting reflectors
behind the tubes is a cheap way to maximise your returns by directing as
much light as possible into the tank. Bright-light plants, which tend to
be those species with light green or red leaves, may need even more
light than 2W/gal., in which case adding additional tubes or switching
to a higher output light source (like mercury vapour lamps) becomes
important. I hope this helps, Neale>
Growing Plants w/o C02 7/4/06
Hi,
<Hi, Pufferpunk here>
I have a 20g standard tank, Eco-Complete substrate tank with one 18w Power Glo
light in the hood. Plants are alive but not growing much at all. I do not want
to use C02. If I bought a double florescent light fixture, would I double my
plant growth without awaking the algae growth?
<It would be helpful to have 2 bulbs instead of one, I have a 90g planted tank
w/4 bulbs.>
I dose with Excel once a week and do a water change as well, 50 percent.
<I am not familiar with Excel. I am having great success using Yamato Green
(www.yamatogreen.com) & Jobe's Plant Spikes placed by the roots--no CO2.>
I am pretty much looking for a low light, low maintenance 20g tank. A friend
of mine (we have the same set-up except for the substrate and the plants) are
not doing too well. One tank that I maintain, has one light, no CO2, Fluorite
with freshwater gravel and the plants are huge--java fern growing all over Tis a
38g tank, and a power-Glo light, the next size up from the 24inch.
What should I do to step my plant growth up a notch, other than CO2, if
possible.
<I swear by Yamato Green! (BTW, please try using proper capitalization next
time you write, as I had to correct for our FAQs.) ~PP>
Stem Plants, Roots, Shrimp, Iodine, and Fertilizers - 06/01/2006
Dear Crew,
<Hi, Shawn!>
I have a couple of questions, but I first want to thank you for the great
resource you have created for all of us amateur hobbyists.
<Your kind words are greatly appreciated.>
I've spent more hours reading articles and FAQs on your website than I can
count.
<Heh, me too!>
With that said, there is one thing I can't figure out.
<.... lots of things I can't figure out....>
I've got a relatively new 55 gallon tank that is heavily planted. It's been
going for about a month now, and is doing great as far as I can tell. The tank
as a Fluorite base, 4 full-spectrum fluorescent light tubes. I use
supplemented/buffered R/O water to do my water changes, and my water levels all
seem good. I also inject CO2, with consistent levels of about 26ppm. On to my
question.... Many of my stem plants (actually all of them) have grown long
white roots from every part of the stem, nearly to the top of the plant.
<This is normal for some plants, like Egeria, Elodea/Anacharis, Limnophilia,
Cabomba....>
Many of these white roots are easily 10 inches long and they are quickly taking
over my tank.
<Today, the tank.... tomorrow, the world!! If they're terribly annoying, I'd
trim them back; otherwise, let 'em have their fun.>
Is this normal?
<For some stem plants, yes. What species are you keeping that are taking over?>
I was hoping that they would just go away as the main roots settled better in
the substrate.
<Some stem plants will settle down and do as you state, some will just keep up
with those shiny white roots.>
Okay, two other simple questions.
<No more! Oh, okay, just kidding.>
I am using "Flourish - Comprehensive Plant Supplement" to supplement my R/O
water (along with Baking Soda to raise the kH) on a weekly basis. Is that
sufficient?
<As long as your KH, GH, and pH are steady, this is fine.>
I am also planning on adding various shrimp to the tank (red cherry & Amano to
start with)
<Excellent! May I suggest "zebra" or "tiger" shrimp? The alpha male of a
colony will be a STUNNING blue with brown-black stripes and red tail and
rostrum. http://www.wirbellose.de/arten.cgi?action=show&artNo=156
>
and read that they need iodine to thrive.
<Yes.>
My Flourish supplement contains 0.0001% iodine in it, but that doesn't seem like
enough. Do you think I should get a separate iodine additive?
<I would. I'm still using Kent marine iodine at a rate of ONE DROP per ten
gallons weekly (NOT the marine dose), but most any marine iodine supplement
could be used in similarly small quantities.>
Thanks for everything you've done.
<And thank you, again, for your kind words and encouragement.>

<Wishing you well, -Sabrina>
Planted Eclipse Tank 5/31/06
Hello all, I have a freshwater planted tank question which I hope you can
assist me with. My current tank is 29 gallon standard with an Eclipse 3
filtration. The current light output is approx. 34-36 WPG
<Mmm, not Watts per Gallon... missing a decimal place?>
which is less than I'd like to have. The current flora: Amazon sword & its
planted baby plants, ruffled sword plant, a narrow leaf red Rubin sword, Bacopa
monnieri, purple Cabomba, bronze wendtii, another young and unidentified crypt,
Ludwigia repens, jungle Val, java moss on driftwood and lace java fern on
driftwood. The current fauna: 6 blue emperor tetras, 4 harlequin rasboras, 1
dwarf Gourami, 3 yo-yo loaches (who like to eat baby Amazon sword leaves and any
water sprite I put in the tank) and about 10 ghost shrimp.
<Sounds very nice>
The tank is a month or so old, with most of the plants and fish moved from a 20
gallon. I have a Fluorite substrate and add Flourish, Trace, Iron & Excel. The
water parameters are 0 ammonia & nitrites, 10-15 nitrates, pH of 8 (central
Florida tap water), and a temp of 79-80. All the retrofits I've found for
Eclipse systems seem to be geared towards saltwater tanks. If I wanted to
upgrade lighting from 34-36 to 55-60 WPG, what do you recommend?
<I would make/do this upgrade. The particulars of light quality, duration are
posted on WWM>
Getting rid of the hood is not an option, as it is new and waste not, want not.
Since the tank is still relatively new and the lighting is relatively low, I'm
also having problems with brown algae. Any advice would be greatly appreciated.
<Mmm, I would not "fool" with the pH here... let it drift down, re-bolster with
water changes. For lighting, please start here:

Planted Tank Set Up Not looking Too Good 5/27/06
Dear WetWebMedia Crew, 5/26/06
I am having lots of problems and I'm not sure what to do anymore.
Tank Specs;
Size: 50gal tank
Filter: HOT Magnum Filter
Heater: Neptune 110w at 79 degrees Fahrenheit
Light: 36", 110w power compact light (with one daylight bulb and one combination
daylight/actinic bulb, for the red lotus)
Plants: Sagittaria subulata, Amazon Sword, Red Tiger Lotus, Green Tiger Lotus,
Ludwigia ovalis, Frogbit (recently added 1 week ago), and Dwarf Hairgrass (which
I am currently removing due to problems mentioned below).
Substrate: Fluorite
Fish: 1 Bristlenose Pleco (female so no bristles); 2 neon tetras; 5 green
fire/flame tetras, 2 blue rams (1 male 1 female); 2 kuhlii loaches (which are
very fat and I hardly ever see); 2 guppies (1 male 1 female); 1 red-tailed
catfish; 7, 4 month old peacock gudgeons in a breeder net; and 2 Amano shrimp
(which I also never see so I don't know if I still have them).
I know I have Malaysian snails in my tank, which don't bother me so much, but I
do remove them when I see them.
My tank has been setup for almost a full year. I use my filtration system mainly
for mechanical filtration only. Lately I have had to add some of Seachem's
"De-Nitrate" for problems mentioned further on. On occasion, I will also run
charcoal in the filter, but for no longer than 2 weeks at a time (depending on
the situation). Unfortunately the filter does not seem to run as strong as it
did when I first got it. I noticed the change about a month after I owned it
actually. I have no idea why it's flow output seems to have changed, as I
disassemble and clean it every week so it is never clogged. For the first three
or four months the tank looked great, but about 3 months ago I started having
algae problems (which are expected I know) which seem to have gotten
out-of-hand. The biggest problem algae is a brown/red/black
algae that forms on the leaves and stems of the Sagittaria, Ludwigia, Hairgrass,
and on the edges of the leaves on the lotus's and Amazon sword. I've tried to
rub it off with my fingers but that does not remove it. It formed on the intake
tube of my filter and the only way to take it off was to scrape it with my
fingernail.
It first appeared on the dwarf Hairgrass and my speculation is that because the
dwarf Hairgrass and Sagittaria grow so compact and fight for space, they added
to the lack of flow at the bottom of my tank and the algae continued to thrive.
I have since started ripping out all of the dwarf Hairgrass and all "infected"
Sagittaria. It grows all over the Ludwigia, which I fear I may have to remove
completely. It also grows on the edges of the leaves on the lotus's and the
Amazon sword, and I remove the leaves promptly to avoid it spreading to the
other leaves.
I stopped adding so much fertilizer in the water (and only plant-tabs to the
substrate) to try and "starve" the algae, which didn't seem to work. I ended up
with varying green colored algaes, which don't bother me so much but I think
they are really destroying the Ludwigia, which doesn't help the other plants.
Now the big problem, I live in an apartment in a city, and starting one month
ago the nitrate levels straight out of the tap are at 10ppm. I only
discovered this because of the giant loss of peacock gudgeon fry after regular
tank maintenance. I had a fry tank in which I was rearing 30 or so peacock
gudgeons (Tateurndina ocellicaudus), but have since discovered that this species
is especially nitrate sensitive and ended up losing all but 7 fry (at the time I
lost them they were a little over 3 months old). The nitrates could have been
rising to this level over the past couple months and adding to the algae
problems (until recently I hadn't really done regular water-testing).
Who knows what the phosphate levels are at (I've read that phosphate test kits
can be unreliable and therefore have not purchased one).
Right now my water is yellowish and somewhat cloudy. Half of me says the
yellowness is from the African driftwood (that stuff never seems to fully get
rid of its tannins), and the other half of me thinks it may be part of the algae
problems I'm having. The cloudiness comes from me adding alcohol to the water to
create bacteria blooms and get rid of the nitrates (I have a bubbler running in
the tank so the fish don't suffocate).
I only feed my feed once a day, or once every other day, but the peacock
gudgeons are fed about 2 drops of baby brine shrimp twice a day.
I can't do water changes because of the nitrates out of the tap. After
relocating the remaining gudgeon fry to the 50 gallon in a breeder net, I
setup the ten gallon as a "pre-treated water" tank so that I could do water
changes with no worry of nitrates. I add alcohol to that tank too, though I
don't know yet if it has actually worked to get rid of the nitrates (had not
tested yet).
It now seems that I need to stop adding alcohol to the 50 gallon tank, as it
seems that the bacteria in that tank may be suffocating or causing my plants to
decay (especially noticeable on the Frogbit). And the nitrates are most
definitely gone (have not checked it since Sunday 5/21).
I think some of the problems are...
1) Lack of water flow. The HOT Magnum is supposed to do 245gph, but as I said
it's flow seems to have decreased since the original purchase.
2) I can't do water changes. If you know of a way to turn the water out of my
tap into safe water for changes please let me know (but know that I cannot
afford RO filtration)
3) I also think my lighting is going downhill. I changed the bulbs about 2
months ago, but I have noticed that the class canopy prevents a lot of light
from actually entering the tank.
Please help. If this sounds like anything any of you have ever come across
please let me know. I would greatly appreciate any knowledgeable input.
Sincerely, Jocelyn
< The algae usually comes from excess nutrients. If your plants are not actively
growing then those nutrients are available to the algae. Plants usually like
lighting in the 5500K to 6500K temp range. The stem plants usually need CO2 to
thrive. I would do a 50% water change, vacuum the gravel and clean the filter.
Stop adding fertilizers and get lights in the desired color temps. Get rid of
the stem plants. They are slowly dying anyway. Get some easy to grow
Cryptocorynes and sword plants. If you are not going to get an R/O or CO2 system
then you need to go with the plants and animals that will survive in the water
and system you do have. The HOT Magnum clogs up quickly, especial with lots of
dead plant material being sucked up. Lots of fish can handle nitrates in excess
of 10 ppm. In some agricultural areas the nitrates come out of the tap at 50
ppm! They still keep fish. Get an outside power filter that pumps at least 250
GPH. Plants need some current to bring the nutrients to them. Stop adding
alcohol, start doing water changes. Get a smaller tank for your gudgeons and
keep them with bottled water.-Chuck>
Air pumps, aerating planted tanks - 05/13/2006
I was reading in a book and it said that keeping air pumps on during the day
is not really a good idea... if you have plants.
<Can be detrimental... as this "drives out" Carbon dioxide, adds oxygen...>
It did not really give a reason but it said that since photosynthesis stops
during the night hours,
<Actually... the dark reaction/s of photosynthesis occur during non-lighted
periods...>
and everything in the tank gives off carbon dioxide, that it is a good idea to
have an air pump / air stone running at night. Should I leave air running all
day or do what the book suggests.
Thank You
<I would likely leave all running continuously... much more to this "story" then
stated here... likely other factors are much more important to your overall
plant growth, health... Too much chance, possibility of trouble with leaving
gear off... Bob Fenner>
Oodles of Planted Tank Questions - 05/10/2006
Hi Crew!
<Hi, Kerry!>
Last year I wrote with concerns about the pond fish I was overwintering
in my 150 gal tank. I finally solved the goldfish waste problem by
finding a new home for the fish and am now hoping to create a planted
freshwater tank. I purchased the tank used and it came with a UGF, a
Magnum 350 and an Emperor 400 for filtration and 2 36" strip light for
illumination. For the goldfish, I added 3 400 gph powerheads, a HOT
Magnum with bio-media, 2 corner filters (recommended by Bob) and a
double bulb strip light so I could actually see the fish.
<Heh, that always helps!>
I have been doing lots of reading and catalog looking to try to educate
myself about what changes I'll need to make in order to have success
with the plant tank. I've kept fish as a novice hobbyist for about 20
years and had lots of fun with a 75 gal tank filtered by a UGF and 2 HOT
magnums. It had 120 watts of full-spectrum lighting and I had pretty
good luck with my tetras, jungle Val and some crypts. From my reading
I'm guessing most of that success was plain luck, but I certainly
enjoyed the experience and would like another beautiful tank. I guess
I'd like to make the move from novice to intermediate hobbyist.
<Onward and upward! Though I'm not exactly sure what constitutes
novice, intermediate, and beyond - I guess it's all a matter of
perspective.>
My questions now are about substrate, lighting and filtration. The tank
has probably 200 lbs of gravel on top of the UGF. My thought is to add
75- 90 lbs of fluorite to the gravel. Is that adequate or would a
different plan be better?
<Mm, probably just fine. Partly depends on your complete "game
plan". What kinds of plants do you wish to grow?>
Should I remove the UGF plates or just cap off the riser holes?
<Get rid o' that sucker. It's a trap for all sorts of awful stuff. If
it's not in use, ditch it - and if you're going plants, for the most
part you won't ever want to use a UGF. I think we had a fun thread on
the forums for innovative uses for used UGF plates.... I believe
"square Frisbee" was one suggestion.>
After all the reading I've done I'm pretty confused about lighting.
<It's a confusing topic, to be sure.>
I need to keep the tank covered and I don't have the inclination to
suspend light fixtures, so I would like to stick to fluorescent
lighting. I understand the idea of watts/gal, color spectrum and such,
but there are so many options to get there! Are compact fluorescent
lamps better than regular lamps?
<Depends on your definition of "better", and (the REAL question) what
plants you want to grow.>
How would it work to have a combo of compact and regular tubes?
<Depends on what plants you want to grow. But, for all practical
purposes, there's nothing wrong with using both. My own personal
preference is toward T5 fluorescent lighting; I just like the look of
it, and you can really pack a lot of bulbs in not much space.>
I have seen two and even three lamp strips offered in catalogs and have
no clue what would be best. How many watts per gal do I want to shoot
for? I was thinking between 2.25 to 2.5. Is that enough?
<Guess what? Depends on what plants you want to grow.>
I would like to avoid some of the problems I've read about that are
caused by too much light. Would there be any need for added CO2?
<Depends on.... oh, you know the drill.>
I know I'm going to have to invest some $$ into the lighting, but I'd
like to do that just once, so I would appreciate any specific
suggestions you are willing to make. Filtration. I'm gathering from
the reading that I should scrap the Emperor 400 because of surface
disruption and just use canister filters.
<Probably. Though I'll admit that I'm guilty of having had a very
successful plant tank while using an Emperor 400. I even had a lowered
water level, but got around the "extra splashiness" by siliconing a
piece of Plexiglas to the lid for the water to trickle down.>
I have the Magnum 350 and I still have the 2 HOT magnums I can use.
<You may very well be able to get by with these.>
Would I be better off to purchase another canister filter instead of the
2 HOT Magnums?
<Not necessarily. My preference in plant tanks is the Eheim
Professionel II series; these are like the Lamborghini of canister
filters.>
And is there any use for the powerheads in a planted tank.
<Depends on the plants and animals you wish to stock. They're certainly
not "worthless", nor "necessary".>
When initially stocking a plant tank, how many plants should be added at
once?
<Can do quite a lot initially, if you fertilize well enough, ultimately
meet their needs.>
Is it different from the slow stocking of fish?
<Yes. The plants aren't going to produce deadly amounts of ammonia or
anything like that.>
I am disciplined (my friends might say compulsive) about proper tank
maintenance.
<Disciplined.... Compulsive.... It's all the same! <grin>>
I have always been good about regular water changes and filter
cleaning. From my reading I am guessing that gravel vacuuming can be
reduced and after thinking about livestock options the only fish I'm
sure to add are Kuhli loaches, just because they are my favorites.
<Hmm.... You might look into "Eco-Complete" rather than Seachem's
Fluorite. It's not as sharp and jagged.>
I would guess I might add a few tetras or barbs later.
<You'll have the space for plenty more than a few!>
Anyway, thanks for any suggestions and advice you have to offer. It's
been a dream of mine to have a tank this size, I want to do it as best I
can. Kerry
<My first, strongest suggestion to you - take a good read through
"Encyclopedia of Aquarium Plants" by Peter Hiscock and "Ecology of the
Planted Aquarium" by Diana Walstad. These will be VERY valuable
references to you; especially the former. You'll learn about how
fertilization, CO2, and lighting work together, how overages in any one
can cause algae, what plants have what needs, substrates,
filtration.... Oh, the list goes on and on and on. You'll get far more
information from these than I can give you in an email. Read these
books, then use them to help you form a "game plan" as to what plants,
fish, and invertebrates you might want, and how you should do it. The
research is probably half the fun, here, so enjoy! Wishing you
well, -Sabrina>
Planted Tank Thanks - 05/11/2006
Hi Sabrina, Thank you for you kind reply. Even though I was not specific
(because I am truly undecided) about the plants I want to grow, you were very
helpful.
<I wish I could have given you something a little more concrete than "It
depends...." but much really does depend upon your ultimate plans. Do please
pick up those books, especially the Hiscock book, to help you formulate and
execute your plans.>
Thank you again, Kerry
<Glad to be of service. Wishing you well, -Sabrina>
How to keep live plants cleaner - 04/27/06
Hi! I really love your web site, so much great information! I have been
searching your web site and apologize if I am asking a question you have already
answered that I just didn’t see. I have read your section about live plants and
I don't know what I am doing wrong. Here is a little background and I hope I put
in all of the important information. I have a 10-gallon aquarium. I have had
this aquarium going for a little over a year. I currently use a filter that
hangs off the back, it uses carbon and sponge
filters, I believe it is called an Aqua10. I change the filter about every 3-4
weeks. I have a bubble wall. I keep the lights on for about 12 hours a day. The
aquarium isn’t in direct light but there are windows in the room. I have 7 live
plants-4 water sprites and 3 Amazon swords. I have had these plants for about
3.5 months. They appear to be ok in that they have new growth. I have an Oto, a
small green catfish, an African dwarf frog, a few neon tetras, a couple gold
skirt tetras, and one dwarf Gourami. I do a 25% water change weekly and when I
do the water change I use a scraper to get green algae spots off the glass and
try to scrub what looks dirty.
Everything has been fine during the year I have had this tank and I dearly love
it. I have a question though. The water looks clear but the live plants have
green algae spots on them, some leaves seem to get dirtier as time goes on get a
brownish build up which I try to scrap off, (at least the worst spots). Is this
normal? Do you have any thoughts on how I can keep my plants
cleaner? Thanks in advance, Kara
<Mmm, the information you present is good, accurate, but incomplete. What re
your water quality? Likely something is amiss here. Please read:

New Plants Stressed The Fish 4/21/06
Hello there! I am writing on behalf of my fish. Here is what is happening:
Yesterday I placed about 13 bunches of Rotala macrandra into my 65g tank. This
afternoon I noticed that all of my fish are "gasping" for air. I tested my water
and the results as follows: pH 6.7, ammonia 0.25 and nitrite was high as well.
There also appears to be a film on the surface of the tank water? The
temperature is set at 28*c. The inhabitants are a small angel, 3 bristlenoses ,
3 Cory cats, 2 dwarf cichlids, a black ghost knife. All were gasping and I'm
really worried. What do I do? How can I lower the ammonia and nitrite levels.
Everything was fine until i added those blasted plants, do you think the plants
may be to blame? Just looking now there appears to be white flaky debris coming
from the filter and floating in the tank. Please try to help me the best you
can, I followed all the rules re setting up a planted tank and now this. I don't
want my fishies to die!! Yours thankfully Jarryd
< A couple of things could be going on. If there is lots of junk in the gravel
then it became free in the water when you planted the new plants. Bacteria
should have handled it but sometimes food/waste become clogged in the gravel and
without oxygen the bacteria have a hard time breaking this material down. Try
vacuuming the gravel to remove this waste and your waste levels should decrease.
When you add plants they increase the oxygen and absorb the CO2 in the water
when the lights are on. When the lights are off the process is reversed and the
plants absorb oxygen and put out CO2. Too much CO2 creates carbonic acid and can
seriously lower the pH in a tank in which the water is very soft. If you added
all these plants without turning on the lights then this might just be your
problem.-Chuck>
More FW crustacean stocking - 04/20/2006
Hello WWM Crew!!
<Hello, Don!!>
I've been reading (and enjoying) the copious information on your website and I'm
very grateful that there are people such as yourselves that take the time to
further (and better) the aquarium keeping hobby.
<Thank you very, very much for these kind words.>
Now that I've gotten the accolades out of the way, on to the questions. First
off, Hi! I'm Don!
<Hi! I'm Sabrina!>
My partner, Richard and I, are in the process of losing our freshwater, planted
aquarium-keeping virginity.
<Oooooh, exciting!>
So.... we have a 37 gallon, bow-front, acrylic tank that currently houses:
6 fancy guppies
6 Rasbora tetras
6 Penguin tetras
10 Neon Tetras
6 freshwater clams (I suppose they're there, I've never seen them!)
<These actually fare very, very poorly in aquariums.... They need copious
amounts of free-floating algae and other micro foods to stay alive.... if
they're not gone now, they will be soon, I'm afraid. I heartily advise against
getting these again.>
2 Flower Shrimp (one passed)
<Sorry to hear this! Shrimp are my fave....>
3 (I think, but I've only seen 2 as of late) Cherry Shrimp
<The third's probably in there somewhere.>
3 Japonica shrimp
6 Otocinclus catfish (they've been miracle workers when it comes to clearing out
all algae growth in our tank!!)
and various snails (I believe there are 3 Ramshorns, 3 black mystery and 6
zebra)
we have 2 medium sized pieces of natural driftwood, adorned with java moss (that
has yet to take root but has been tied/anchored with peat moss)
and many many live plants.
<So far, so good, aside from that shrimp....>
Our water has a pH of 7.6 out of the tap, and in the last few days we have had a
measurable ammonia concentration of approx. .25 ppm.
<Disconcerting, but not "deadly" as yet.... do please try to bring this to
zero.>
Nitrates and Nitrites remain at 0.
<Yikes! Still cycling??>
Herein lies the issue. I've learned from reading on this site about the cycling
process that
one should endure when setting up a new system. We have not followed those
guidelines, unfortunately, and are now likely experiencing the fallout from such
rash behavior.
<Yup. But you're learning.... and I'm very happy for that.>
Needless to say, we have overstocked our tank (a sign of our eagerness to house
and grow live
aquaria)
<Mm, I wouldn't say you're overstocked, but stocked too much too quickly.>
and after becoming attached to our inhabitants, are doing our best to ensure
their ongoing well-being. So here's where I need a little guidance in the
process. Since the damage is pretty much done and we've overstocked our new,
un-cycled tank, what measures are required to keep the aquaria we're currently
housing, relatively healthy and un-dead, for lack of better terminology. From
what I've read on this wonderful site, water changes are pretty much par for the
course and we're doing those (approx. 5 gallons a day, sometimes twice a day
depending on the ammonia concentration) to keep our inhabitants as happy and
healthy (not to mention un-dead) as possible.
<Perfect.>
We have also used Marineland Bio-Spira (last weekend) and are currently using
Fritz-zyme Turbo 700 to hasten the cycling process and as a stop gag measure to
stave off any further loss of life.
<Perfect again.>
We had a blue crawfish (Procambarus sp.)
<Yeeeeeee-ikes! Not with the shrimp, please, nor with any slow-moving or
bottom-dwelling fish - they'll all become snacks.>
and one of our japnionca shrimp recently pass on (not sure if this was due to
the un-cycled-ness of our tank or the trauma suffered during shipping).
<I hate to say it, but be glad for the lack of the Cray. Crays are GREAT, but
really ought to be with critters that they can't or won't hurt. The shrimp and
otos are not in this category.>
So I suppose my formal question is: Should we be doing as many/as frequent
water changes as we are doing, in lieu of the cycling process not being
completed, even though we've used the previously
mentioned products (Bio-Spira/Fritz-Zyme Turbo Start)?
<I would, yes.>
I guess I could/should make that a little clearer... Are we doing more harm
than good by changing the water so often, or should we allow the ammonia to
build to a level, just shy of tolerable for our
tank inhabitants in order to promote bacterial growth, or should we continue
with the water changes to keep the ammonia concentration at a less-than-lethal
level for our overly stocked tank?
<Though it will prolong the cycling process, keep up with the water
changes.... The cycle will establish, it'll just take a little longer.>
Other issues we're grappling with are whether or not the 3" fluorite substrate
has a negative affect on our invertebrate aquaria (after-all we did lose 2, I've
read about copper being adverse to their livelihood and I'm not sure if fluorite
is detrimental to their well-being)
<If it helps any, I've used fluorite in plenty of shrimp-containing tanks with
no apparent negative results. I would not be concerned here. In all honesty,
freshwater shrimp are not always cared for properly at stores and wholesalers;
these animals may have been doomed prior to purchase. When you buy shrimps and
crays, you should look for a certain quality of "clarity".... Hard to describe,
but once you've seen/recognized what I mean, you'll understand. "Cloudy" shrimp
should be avoided. This "clear" vs. "cloudy" can be seen even in totally
colored shrimp, like wood/fan/Singapore shrimp.... again, it's tough to
explain.>
and does iodine (added as a supplement to aide our invertebrates) have any
affect on the fish we're keeping?
<Nope, not a problem at all - and of vital importance to the inverts.>
We do plan on getting another blue crayfish (Procambarus sp.) to replace our
recently deceased
<I recommend strongly against this.>
and we'd like to add a few more fish (probably compatible tetras or another
species you'd recommend that's compatible with the above mentioned, currently
housed aquaria and more shrimp (they're too cute to resist)).
<I bet you'd really delight in the antics of a handful of small Corydoras cats,
or if you fear outbreaks of undesirable snails, a few Botia striata....>
Thanks in advance for your informative response
<Glad to be of service!>
and sincere thanks for providing a forum for all of the unlearned yet eager
novices (such as myself) new to the 'trade'.
<And again, thank you VERY much for these kind words.>
Don Anderson
<All the best to you, Richard, and your new tank! -Sabrina Fullhart>
FW free floating algae & QT question 1/20/06
Dear WWM Crew,
I'm in the process of setting up a small FW planted tank after moving and
losing my Xeniid reef tank -my current apt won't support the weight... I'm
up to a very rocky start. My first setup was ruined by a yeast fermentation
process that went out of control and ended up in the tank! It lasted 3 weeks.
<Can be a real mess... disaster>
Current setup - The tank is a 20 long with 3" of Fluorite and 1/2" sand on
top, 130W of 10,000K PC -like the color more than 6,500K! It's been set up
for 2 weeks with 4 Anubias sp. and 6 Cryptocorynes that survived the original
setup. Not yet cycled...
<Leave it be till it is>
The 10G QT is cycled and has one Tiger Lotus, some Microsword and Giant
Duckweed and one male Golden Wonder Killi. The fish still needs to spend 3
weeks, but I would like to transfer the Tiger Lotus and Microsword to the
display.
<Best not to move these Lotus...>
I have 130W of 10,000K PC here too. Problem is the QT has green water due to my
over feeding of the Killi! Based on what I've read I should
solve the green water problem before I transfer anything from the QT to the
display, but I don't think the Tiger Lotus is going to be happy much longer
not anchored to the substrate. Any suggestions? Opinions?
<I would add a sponge filter, keep doing partial water changes... leave all in
place for now>
Also, for tank mates for the killie, I was thinking of either a pair of dwarf
gouramis or one male betta, although I am not sure of the latter and
want to try their compatibility while still in QT.
Thank you,
Narayan
<Either should work out fine. Bob Fenner>
Going From SW to FW 12/16/05
Hello, I have a 38G tank and want to set up a planted tank. I have
kept freshwater tanks for years now but have never tried planted. I
have some questions. I have a 36" Orbit Power Compact fixture with a
96W Dual daylight 6700/10000k bulb and a 96W Dual actinic bulb, from
a failed Saltwater tank endeavor (that's another story for another
time). Anyway would this light be sufficient if I didn't use the
Actinic. Or should I try to replace the bulbs with 100% 6500k bulbs?
< The latter would give you the best results.>
I'm also a little confused on C02 I have read that if I don't add C02
the plants could use up the available C02 and my pH will rise, but if
I add too much C02 the pH will drop, I don't know what I should do. I
am also considering using Flourish Excel in place of C02, have you
had any experience with this product? Thanks for the help and any
other suggestions you could make would be appreciated. Thanks
< Individual stem plants do best with CO2. Plants like Amazon swords and
Cryptocorynes really don't need CO2 but do better with it. Go to
Aquariumplants.com. They have lots of beginner plants to get you started. Excel
adds iron not CO2. Plants require both. I would recommend Fluorite as a
substrate, 6500 bulbs, swords, crypts, anubias, java fern, Aponogetons to get
you started. You can still set up a pretty decorative planted tank without using
CO2. During the day plants take in CO2 and give off O2. It is reversed in the
dark. CO2 generates carbonic acid that affects pH. Usually there is enough
minerals in the water to offset or buffer major changes in pH.-Chuck>
Green dots on plants 6/29/05
Hi,
<Hello there>
Thanks a lot for such a wonderful website.
<Welcome>
I have four Mickey mouse platies and four black skirt tetra in my 20 gallon
tank.
My water test readings are as follows:
Tank Specs: 20 gallon with BioWheel filtration system.
Water Temp: 82 F
Ammonia: between 0 ppm
Nitrate: 20 ppm
Nitrite: between 0 to 0.5 ppm
Hardness: 150 ppm
Alkalinity: 40 ppm
pH: 7.0
Two days back, I have noticed some green dots on artificial and live plants.
These green dots are only on some leaves of a live plants and on top leaves of
artificial plant.
<Ah, yes>
I have assumed they would be algae but after researching online, I found that
algae has brown like color mostly.
<Mmm, no... come in all colors, but most freshwater aquarium algae look/are
green>
I am worried what these green dots are in aquarium. Is it algae? If yes, then
what should I do to get rid of it. If not, then what else it could be?
Thanks a lot for your help in advance.
Regards,
Min

Aeration and a Planted Tank - 06/07/2005
Thanks for all the good advice so far. It has been very helpful over the
years.
<I am delighted that you have found WWM useful; thank you very much for the kind
words....>
I have a 90 gallon tank...18 months old...with two Emperor 400s, 80 degrees, 5
angelfish, 11 Cory cats, and 7 Bristlenose Plecos...the Plecos spawn constantly.
<An excellent bonus, to be sure!>
I also have a 30 gallon cube...one month old, but I stole a BioWheel from my
established tank...with an Emperor 280, 75 degrees and two goldfish...an Oranda
and a moor. I change 10% of the water every day and vacuum the tanks once
weekly.
<Wow! You've sure got me beat. I tend to be a lot more lax about
maintenance.... Now, I know we typically crack the whip on folks and tell them
to do MORE maintenance on their tanks, but a word of caution, if you plan to
plant a tank heavily, you'll not want to vacuum the gravel each week.... and,
being that the substrate is where your little nitrifying pals colonize, be sure
not to be *too* thorough in your weekly vacuum job.>
I have been running air stones in both tanks...2 in the 90 gal and one in the 30
gal...to increase oxygen content in the water.
<I'm sure the plecs and Corys especially delight in this, as they come from
areas that usually have high oxygen content, though it may not be an absolute
necessity.>
I bought a small piece of Anubis Nana rooted on bogwood for the goldfish tank
and some Java Fern and Anubis Nana for the angelfish tank which I tied to
existing bogwood so it could root. The LFS told me that I should discontinue the
air stones now that I have added plants...something to do with CO2 levels. Is
that right?
<Well, yes and no. These VERY hardy plants will take just about anything you
can dish up - very low light, low CO2, low nutrient levels, etc., etc.... You
need not change anything you are currently doing to please them. You can keep
your aeration, maintenance scheme, and all.>
I do not want to stop the extra aeration if I don't have to do so.
<No worries. If you choose to plant the tank heavily with plants in the
substrate, you'll want to make some major changes (less frequent gravel
vacuuming, for one), but the Anubias and java fern will do fine for you. You
could lightly plant the tank with plants in the substrate, as well - if you do
so, I would recommend heavy root feeders like Amazon swords, Crinum or
Vallisneria, Cryptocorynes, and Aponogetons, and give them some nice fertilizer
tabs in the substrate around them, and you could still keep your
aeration.... If you plant the tank heavily, though, you'll want to do some
research on how best to change your tank. Diana Walstad's book on low-tech,
low-maintenance planted tanks is great, as is Peter Hiscock's "Encyclopedia of
Aquarium Plants", which details lighting, fertilizing, adding CO2, and much much
more.>

<Wishing you continuing success with your aquaria, -Sabrina> Floral mayhem
Hey crew,
<David>
I am having some serious problems with a number of my plants. The
pattern of symptoms does not seem to correspond to anything I have read
on macro/micro element deficiencies.
<Okay>
Holes in leaves. This has affected a couple of the broader-leaved
plants (e.g. one of the larger Echinodorus [rubin? red flame?]).
Stems rotting. I had a Myriophyllum aquaticum completely fall apart in
about 3 weeks. Now this is starting to affect even my hardy Hydrocotyle
leucocephala and Alternanthera reineckii -- both of which have been
growing like weeds.
<Mmm...>
Whitening of leaves: The leaves of the Hydrocotyle also started
whitening starting at the edges of the leaves after a couple of months.
Some of the leaves which have NOT shown this whitening now have small
bright green spots???
<Algal likely here>
Browning/curling of leaves: This has affected only my Hygrophila
difformis, and only on a few leaves.
<Nitrogen, ready solubility issue>
Vallisneria fare particularly poorly-- blades start melting within days
after I introduce it to the tank. The smaller spiral
variety-of-many-names dies almost immediately. One of the larger
varieties is hanging in there, the root system is actually very well
developed and even sending out runners, but most of the blades just melt
and/or come off.
So-- seemingly different symptoms on different plants, with stems
rotting being the most common symptom.
<Of the general possibilities... pathogenic, nutrient limitation,
environmental... which is it?>
The tank is 12 gal, about 3 months old. Lighting is a 24W "6500
daylight" compact fluorescent. Generally most of the flora seem to do
fine for somewhere between 2 weeks and 2 months before these symptoms
begin to show...
Overall, given lack of CO2 injection, growth seems very good and
consistent. Even the worst-hit plants (Myriophyllum and Vallisneria)
show relatively vigorous growth even as they die!
I am using a manufactured substrate called Florabase.
Don't know much
about it, other than that it contains volcanic ash (according to mfg),
is supposedly high in chelated iron, and is apparently poorly named.
<Red Sea product... I like others better>
It
is acidic -- rapidly and significantly reduces/buffers pH and KH -- but
I don't think it contains peat, at least the water doesn't look it.
Grains are 1-2mm with a moderate amount of silt (package specifically
said to not rinse prior to adding to tank).
I am fairly certain that these problems relate to the substrate in some
way, just not sure how. My main reason for thinking so is the extremely
fast decline of any type of Vallisneria. I had a couple of different
varieties in another tank with plain old gravel and poor lighting, and
they did just fine... and are supposedly very hardy.
To give you some idea of the acidic properties of the substrate...
Tap water: pH 8.2, KH ~2.5d, GH ~4d
Tank water: pH 7.0, KH ~1d, GH ~4.5d
Other stats: NH3/NH4, NO2, NO3 all undetectable. Free/chelated FE
undetectable. Water temp 79F. Fauna consists of 1 Betta, 2 Colisa
lalia, 1 siamensis, 3 platies, relatively tame snail population.
Apologies for the long email, and thanks in advance for any help you can
offer...
-Dave
<Mmm, am given to suggest (due to small size of the system), tearing down,
replacing the substrate with SeaChem's (Fluorite) line... and their fertilizer.
I do think the substrate is principally at fault here... not supplying
carbonate, in fact being too-reductive (acidic), mal-affecting nutrient
assimilation.
Phosphates, algae, PMDD, and CO2 injection
Hey, WWM-ites,
<Glen>
Once again, thank you for your time in answering all our questions. The
Wife has OK'd making a donation on your new Amazon Honor System link (at
the bottom of the homepage, for those of my fellow readers who haven't
noticed it yet) after two more paychecks.
<Thank you, and her>
MacL, your answers on the
acrylic questions will save me lots of money, and I appreciate it!
<Yay!>
I've arrived at a few more tentative decisions for near-future
directions, and would appreciate feedback.
<Okay>
We started our 55g freshwater community tank with sodium biphosphate (to
drop the pH 9.5+ tapwater here in Austin),
<Wowzah! Liquid rock!>
phosphate buffers and fake
plants. We've swapped out most of our fake plants for real ones now,
and I've stopped adding more phosphates now that we have a luxuriant
carpet of algae (more on that in a minute). From what everyone says,
using a phosphate buffer in a planted tank is pretty well guaranteed to
cause rampant algae growth.
Am I wrong in understanding it this way?
<Mmm, can, but not necessarily>
Based on this theory, I'm using Poly-Filters (for the last three days)
in the Emperor 400 to extract the phosphates. Doesn't this remove the
buffering, as well?
<Mmm, no... not carbonates, bicarbonates... unless they are bound with metals>
(Seems like a "well, duh" question...) I monitor
the water chemistry religiously; test the pH (7.1-7.15) at least twice a
week with a meter (calibrated every few weeks), do reagent-based nitrate
tests (never above 20ppm) twice a week, and ammonia and nitrite tests
(both 0.0) every time we've added livestock (but we're at max population
density now, so those will go to once a month unless something looks
awry).
<Outstanding>
We change 14+ gallons every week (we make 25 gallons at a time
in a dedicated trash can), and with my new phosphate-free regimen the pH
is 7.05 to 7.1, but the new-water kH is zero.
<I would add at least a few heaping tablespoons of sodium bicarbonate to each
batch... or if you'd prefer, a commercial product containing this, some
carbonate, borate...>
I bring the tap pH down
to just acidic with hydrochloric acid, and balance it back to neutral
with sodium bicarbonate - fairly easy to achieve, but a bit too much
either way and the pH goes to either under 6 or straight to 8.3 (sodium
bicarb buffer point).
<Oh!>
If the Poly-Filter removes all the phosphate
ions, and hence all the buffering in the tank, how fast can the dreaded
"pH crash" happen? Hours/days/weeks?
<Days, could... likely there is some other buffering mechanism at play here...
substrate, decor...>
With the water changing regimen,
is it still as big a worry?
<Not "that" much>
Should I spend the money for a "system"
like Seachem's Acid/Alkaline Buffer additives (chemically almost the
same as what I'm doing now, AFAIK), and add the appropriate blend of
them after I've achieved neutrality?
<Up to you... I'm a cheapskate and so would not>
I've spent hours on the Internet
investigating buffers, and there apparently isn't anything remotely as
stable as phosphate buffers (without getting into exotic DNA-analysis
stuff at $35 per 100 ml). Right? Worry or not too?
<Not too... do what I would... add a gallon or so of just straight tap to the
whole shebang. No big worries re pH...>
When we added our first live plants (Vallisneria and Cabomba) we got
quite a growth of hair algae on the Vallisneria and a bit on the edges
of our silk plants. (From pictures on the Internet, it looks like Vals
are a pretty good growth medium for hair algae.) We've since added more
Cabomba, some dwarf and giant hair grass, a huge planted watersprite
(and some floating), a wad of Java moss, some Ludwigia repens, a cluster
of Alternanthera, and we just planted two tiger lotus bulbs which
haven't sprouted yet. All the plants are doing better than I expected
them to, especially after upgrading to a 110-watt compact fluorescent
fixture (the AGA with GE 9325K bulbs). The Vals are sprouting nicely at
the main plants and sending runners everywhere - we have sprouts coming
up nearly two feet away from the main plants.
<Neat... and good bio-assay evidence of no outright shortage of macronutrient/s>
I've been cutting out the
older worst-covered Vallisneria blades to physically remove the bulk of
the hair algae (the scorched-earth philosophy), and am going to see if
the color in the silk plants will stand up to a bleach dip to kill the
algal inflorescence thereupon.
<Should do so... and/or keeping them in the dark for a week or so>
Y'all have indicated that patience,
rational fish-feeding, and healthy plants will eventually starve out the
rest.
<They will>
I've just ordered the components for making some PMDD to boost
the plants' micronutrient levels (particularly the iron, as I understand
it's important to the algae battle) and will let you know how/if it
works. Any other suggestions (other than CO2, the next subject)?
<For others reading this PMDD is an acronym for "Poor Man's Dupla Drops"... an
ersatz near formulation of Horst and Kipper's business (Dupla) complete plant
fertilizer product... you can see more re this on "the krib" (search via the Net
please)>
I've pretty well convinced myself to put a yeast-based DIY CO2 injection
system in the DIY trickle filter I'm building.
<Neat... and some semi-sneaky advice... start hinting that what you'd REALLY
like for upcoming birthdays, thank yous are carbon dioxide infusion gear... a
five-ten bottle, regulator, needle-valve... as I am VERY sure you will
"out-grow" the pop bottle technology but quick>
I'm thinking about a
forced-water injector in the final sump compartment before the return
pump. The question I have about this concerns our tank aeration. We
have what I call a "wall-'o-bubbles" along the back of the tank - a 36"
bubble stick (at my Wife's request - she loves the look).
<Wow! And a humong oh air pump I'll wager>
I know that
aeration is danged near a cardinal sin in a planted/injected tank, but
too bad - the wall stays, don't argue with Mama. :-)
<Hotay!>
Will the aeration
severely decrease the benefit of an injected system, or is this (1) any
CO2 is good CO2 or (2) who the heck knows, Glen, put it in and find out?
<It will still be of discernible benefit, bubble wall and all>
Will the heavy surface aeration somewhat diminish the pH impact of the
CO2 injection (tying this in with my diminishing buffering capacity)?
<Yes>
Maybe tweak the kH to 90-100ppm or so with sodium bicarbonate after I
start and keep an eagle eye on the productivity of the yeast generator
(since going from pH7.0 to pH8.3 would be a "bad thing")?
<? Yes to raising the KH, GH... the use of CO2 will lower pH, not raise it>

Plant Fertilizer
Good evening,
<Hello...Jorie here>
I've been doing a ton of research on planted aquariums recently because
I'm looking to increase my wattage from 1 watt/gal to about 3.2
watts/gal. I've found the right CF strip light, CO2 equipment, but know I'm
real confused about plant nutrition.
<There's tons of products out there, no wonder you are confused!>
What complete liquid/tablet plant fertilizer do you recommend?
<Personally, I use the SeaChem products, the Organic Carbon for the Planted
Aquarium (which you won't need, obviously, with your CO2 system), the
Comprehensive Plant Supplement and the Flourish Tabs. These combination has
worked quite well for me.>
What trace elements would you consider the most important?
<Hard to say which one is most important...there are really many elements
essential to good plant health.>
Would you consider 3.2 watts/gal "goosing" the light intensity?
<I'm not sure I understand what you are getting at here. What I can tell you is
that 3.2 watts per gallon would be considered "moderate" lighting - what type of
plants are you wanting to grow?>
Thanks for your help
Chris
<If you don't already have it, I'd highly recommend Peter Hiscock's Encyclopedia
of Aquarium Plants - great book! Good luck! Jorie>
Your plant articles
Dear Mr. Bob,
<Ms. Daphne>
I adore your writings! Thanks so much for posting these wonderful articles and
pictures on the web.
<Glad to share>
I have been reading what you put down, though, and I still don't have a clear
cut answer to a question that is plaguing me. I have a 75 gallon,
peat-filtered, Amazon-ish (we'll call it an ish, I'm no expert here) tank with
soft water of about a 6.8 to 6.9 regular ph. I keep the baddies (ammonias,
etc.) down with twice a week water changes, and I have lots of plants. I'm
building up my plant harvest so I can put up a modest 15 tall angel tank (maybe
just a mated pair) in the living room with cuttings.
<Okay>
My question is this. How DO you keep the tank substrate clean? I did read much
of what you posted, but I still don't get it. I have a huge bottom feeding
community. I have 12 Cory's, 2 Plecos, a Chinese Algae Eater, 2 porthole
Flagtail cats, Kuhli loaches, and the main fishies are Kribensis and Cockatoo
Dwarf Cichlids. I love those little buggers. (cacuatoides are my
favorites). So, I have many, many bottom loving and scavenging fish just on the
lower levels. I did this on purpose. I used to have 2 foot long Oscars and an
18 inch pleco in the tank. I found a home for them, a nice 200 gallon home (and
cried when they left), but I think, now, after reading your posts, I did a bad
thing. I kept the giant stones as the substrate.
<Ahh, part of the difficulty... otherwise, doing some surface vacuuming during
your water changes, rinsing out or replacing your mechanical filter media at
these times, possibly adding some increased water circulation... should be about
it>
Yes, I have the huge boulder stuff.
I added lots of tiny rock, so I have a layered thing going on now, and I am
slowly, slowly pulling the large rock out and replacing it (to keep the
biological thing going), but I still have a great deal of large rock. Should I
just put the many plants I have in sectioned pots?
<Mmm, if you'd like... to facilitate their moving about, re-landscaping, but
this is not necessary>
I have red rubin everywhere, purple Cabomba, anacharis, and some pennywort. I
just won a bunch of red and magenta plants off of EBay. I like the idea of
having green all over. However, I do notice in order to feed the bottom guys, I
must often drop flake to the bottom.
<Try sinking pellet type foods here... much cleaner, more nutritious... a bunch
of manufacturers make them... Tetra, Hikari, Omega Sea...>
I like to use a variety for the bottom feeders. It seems to make them
healthy. So, is a gravel cleaner a bad thing? Can I use it in the places where
the plants aren't?
<Just cleaning lightly and not deeply near rooted plants should be fine... is
what I do>
I've heard tell that if you have a very well planted aquarium and feed
correctly, that you don't need to siphon the gravel,
<This is so>
but I am afraid to ignore it. What would you do if you were in my predicament?
<Do half the tank, around the rooted plants each time you're in it for other
regular maintenance, water changes...>
By the way, I use the Python 25 foot thing that attaches to my sink, because a
75 gallon tank is easier to clean in this manner.
<Understood>
Would you be more fierce in getting rid of the big stones? Please let me
know. And, thanks for so much wonderful information. You take care.
<I would switch out the large stones... you mention ammonia, but should not
detect any... I would be bold and pull most all of these rocks>

Goldfish, plants, and substrate cleaning
Hello, I have a few questions for ya’ll, hoping so much that you can help
me out.
Tank details: Was a used tank, came with the filter, tank, light, etc.. 60
gallon tank, 304 Fluval filter, Lighting – not sure except that the bulb is
full spectrum light….so not much, help there, unfortunately, Fresh water, live
plants (duckweed and anacharis right now) Substrate is silicate sand, gravel,
and a few larger rocks, but no UGF
Just bought some peat to try out, as well. tank currently has:
3 goldfish (one 5”, one 6 “, one 8 inches long)
4 white clouds
3 Ramshorn snails
Tubifex worms (enough for goldfish to eat a few and keep the sand a bit
aerated, if I understand right. I restock the worms when it looks
like
they’ve all been eaten)
My first few questions are more on method than anything else: I am not sure
how to clean the substrate. I have the sand and gravel mixed, rather
than
the gravel totally covering it, as it seems to make it easier for the fish
to get at the worms. So, I can’t vacuum or the sand is totally
sucked up.
I wasn’t sure if vacuuming was still a good idea with a planted aquarium,
either. What’s a good way to try to clean the bottom? A
particular
creature, a mechanical device, more plants..? I really like to try
and keep
it as natural as possible, so if there was a fish, invertebrate, etc… that I
could acquire that would help and not overstock, I would appreciate a finger
pointing the way to one! We also have a 20 gallon warm water planted tank
that I am going to start up, so if a creature could be used, if you have any
warm freshwater substrate cleaners, I’d love to hear about them as well.
One of the reasons I am concerned is because I HAVE to let the food settle
to the bottom or my goldfish do not eat. They were originally fry
from a
friend’s pond. The pond’s fish population was almost completely
killed off
by a heron, and honest to God, I swear it’s given my fish issues:-P Without
live plants floating on top and many, many around the tank to hide in, even
with backing, rocks, etc. on the tank, they will stay huddled together in
one corner of the tank, scared to death. Even when at ease, They
absolutely
refuse to come near the surface, ever….and we’ve had them for 2 years now,
since they were less than an inch long. They aren’t scared in
general…they’ll even come near my hand in the water and seem to rub along it
whenever I am doing something inside the tank. I’ve tried a
lot of
different things to try to encourage surface, or at least mid-water eating,
but have finally given up and just give them sinking pellets, which they
enjoy rooting around for, but don’t often eat as they fall, even if I am
only feeding very small amounts (tried it to see if I was overfeeding, ya
know?) So, as they don’t eat them as they fall, the motion of the
water
always ends up flowing a small pile of them to some oddball place in the
tank. Usually it’s found and eaten, every once in a while it’s
not. I
worry about any I’ve missed contaminating the tank!
And now, onto what is actually a more vital question for me…I’m having
cloudy water and have recently found a little bunch of food that got shoved
under a bit of wood in the tank…and it’s got some sort of white growth on
it. Looks like each piece of food has acquired a white fuzzy outside
about
a Ľ inch big. once taken out of the water, it seems almost hair like in
consistency. Is this some type of algae possibly? Or does
it sound more
bacterial? Or could it be both? We were in a
bit of a desperate
situation with the goldfish, so, background: They were in a 20 gallon tank
and had a growth spurt like they were competing in fish growth Olympics or
something, jeesh. I was saving for a bigger tank, but even as I got
it,
they were really crowded, I was finding it impossible to keep the tank clean
enough, etc… Really worried about them. I fishless
cycled the new tank,
and when it was ready, I was going to nicely, slowly introduce the fish one
at a time. However, after I introduced the first one, the 20 gallon
situation was suddenly much worse, fish gasping for air at the top of the
tank, etc…so, I decided that putting them in the new tank together, even if
the load was a bit high at first, would be less stressful than keeping them
in that old one. The ammonia level went up to .5 ppm, the nitrite and
nitrate level is very low (dipstick…lame test, but the nearest stores were
out of the more precise ones). I am trying to control the ammonia
levels
with water changes of 2-4 gallons every other day (based on how much water I
can let sit at a time with the buckets I have!) which seems to be working
allright on controlling the ammonia. The ph was at 7, but dropped to
6.5.
I have been using a ph up (can’t recall brand) to bring it up to 7 at the
moment. Had a bit of a brown algae bloom as well. Now that
I can actually
see the goldfish better out of the 20 gallon tank, I’m pretty sure they have
a bacterial infection, based on reading your faq’s on that sort of thing.
Doesn’t look like they have any fungal infections. So…is the
cloudy water
best taken care of through water changes, or might it be more of an
indication of a bacterial problem? Any suggestions on best way to
fix?
Now, I want to medicate, but I’m wondered if it would interfere with the
biological filter trying to straighten out? Melaflux (spelling may be
wrong) was recommended by our aquarium store owner after hearing our fish’s
description. Would it be better to wait for the
ammonia readings to stay
at 0 without the water changes 3 times a week? Or is it usually
better to
medicate first? Fish look ill in physical appearance, but they are
not so
ill that their activity levels or swimming ability seems different than
normal. White clouds seem fine.
Thank you in advance for any help you can give me!!! Shauna
>>Hello. First, using peat is not necessary with goldfish. Second, Tubifex
worms generally come from impure water, are you sure you are using live
Tubifex?? Are these cultured? Unless they are being raised in a relatively
sterile environment, I would never feed these to my fish.
Plants and goldfish are usually a short term arrangement, since goldfish are
herbivorous and will eventually mow their way through your plants. They also
like to snuffle around in the substrate, I am surprised your plants have not
been uprooted yet. You can try adding Malaysian Trumpet Snails, they live in
the substrate and are excellent soil-turners. Other than that, I recommend
you "surface vac" your substrate regularly. If you can remove uneaten
food
and fish poop before it has a chance to become "one" with your
substrate,
all the better. Yes, you will deprive your roots of some nutrients, but you
may hopefully prevent future problems this way. It would also be advisable
to uproot and re-plant regularly to prevent anoxic substrate problems down
the road. I can hear the plant people wincing when I say that, but
this is
a goldfish tank, so, you either need to put the goldfish first, and clean it
accordingly, or remove the goldfish and make the plants your priority. You
can't really do both. Also, why didn't you move the filtration on the 20g
onto the larger tank? This would have helped your cycling process. Cloudy
water is normal when cycling, also pH fluctuations, do NOT add any pH
products, it won't help your fish at this stage! Also, fuzzy, fungus-y food
needs to be vacuumed out!! Keep doing regular water changes, this
will slow
down the cycle, but it will help keep your fish alive. You can try adding
Amrid, or AmmoLock, or any other product at your local fish store, to help
with this problem. Please do these things, then describe what your fish look
like, their movements, etc. I will try to help you figure out if your fish
are actually sick, or are just suffering from the high ammonia problems.
-Gwen<<
Thank you so much for the reply, Gwen! Appreciate the advice
immensely.
RE: the Tubifex worms. Actually, I'm culturing them myself. I
started out
with live ones from an aquarium/reptile store, and accidentally 'bred' an
empty tank full of them, so now I just keep the colony going and gather some
up periodically and put 'em in the tank for the fish.
Oh, regarding the plants...yeah, they're mostly for the Goldfish to eat,
anyway. I have enough that they get a chance to grow, but I just add
in the
cost of plants periodically to the fish food budget. I just don't
want them
to start dying before the fish eat them and make everything worse, ugh.
I think it's all good now, thankfully. After cleaning out and finding one
more spot of yucky white food, I now know where the current seems to be
pushing it in the new tank so none gets left behind now, and the water
cleared right up in just a few days and the ammonia just a bit after that.
Yee ha.:-) Fish are looking good, too, so that's a relief.
Thanks again...any more troubles and I know just who to come and ask now!
Shauna
>>Thank you! I'm happy to hear things are going well. As always, if you
test your water, vacuum, and do the waterchanges, you should have smooth
sailing. If you are concerned about plant matter inside your filters, just add a
piece of foam to your filter intake. Then all you have to do is rinse the foam
periodically. Best wishes! -Gwen<<
Film on top of the water
I have a 72gal fw planted tank that has been established and trouble free for
quite a while but lately a "silver" film is coating the top of the
water. The tank is open with no type of hood. I do 15% water changes weekly,
usually trying to skim all the film off the top but it comes back a couple days
later. The tank is heavily planted with a fluorite substrate, high pressure CO2
injection, two magnum 350 canisters (one with SeaChem matrix bio media, and one
half filled with SeaChem renew, and the other half with SeaChem phosphate
reducing media.), and 260watts of light. The film on the water reflects quite a
lot of light back out of the tank and is getting annoying. There are about three
dozen Nerites snails in the tank and this morning at least 2 dozen of them are at
the top of the tank, and half of those were above the water line. I know this is
a sign of trouble so I did a quick water change before work. All water
parameters are ideal and the fish (various loaches) don't seem like anything is
bothering them. I add a very small qty of iodine at water changes as well as
small amounts of liquid fertilizer. I'm at a loss as to what is causing this
"film", my HVAC system has not been on for several weeks, no type of
cleaner is ever sprayed near the tank, and this problem seems to have come from
nowhere.
<This film could be caused by any number of things, from aerosols (not only
cleaning stuff), kitchen grease 'n' stuff, cigarette smoke, oils from your skin,
even some fish foods (have you changed feeding regime lately?). If
you can't or don't wish to put a lid on the tank, you might want to consider a
surface skimmer; I believe Hagen, Fluval, and Aqua Clear make them, possibly
other manufacturers as well. The purpose of this device is
specifically to remove organic film from the water surface. If you're
able to or don't mind, glass lids would help keep the tank free of stuff that
might collect there, but you'll likely lose a little light into the tank - of
course, I'm sure the scum on top isn't helping with that a whole lot,
either. Also, though this surface film might not be inhibiting the
health of your fish right now, it is undoubtedly hindering gas exchange at the
surface of the water, which might end up causing problems for the fish down the
road, if not quite soon; lack of oxygen might be what caused the snails to crawl
out, perhaps. Everything else with your setup sounds
fine. Hopefully you can find the source of the film and stop it, but
until then, I hope this was of some help to you.... -Sabrina>
Re: sterilizing aquatic plants
Hello, I have a question for the aquatic plant expert(s). I have
a 100G planted tank (440 W of VHO, onyx/fluorite/laterite substrate) that had
several schools of tetra. I say "had" because this tank is
infected with Pleistophora hyphessobryconis (Neon Tetra Disease) and one by one
my tetras kicked the bucket. This tank has been setup for about 2
years and this is the second time I have had NTD tear through my tank, so I am
biting the bullet and sterilizing the tank with bleach and tearing it down and
starting from scratch. Most of the plants are replaceable Val/elodea
etc. type bunch plants, but I have three plants that I would like to keep and
possibly use in the reincarnation of this tank. They are a large N.
japonicum, a massive red N. zenkeri, and a smaller though growing green N.
zenkeri. Do you have any recommendations for sterilizing these
plants? I have read about bleach, iodine, even hydrogen peroxide. The
weak bleach solution sounds the safest but I wonder if it would be strong enough
to kill these damn protozoa’s.
<I’ve heard of numerous ways to “sterilize” plants but the only
absolutely safe way is to quarantine them for a full month. The protozoa’s
won’t be able to live on just the plants so if there are no fish in the QT
tank for at least a month you should be safe. Also, if you do this you should be
able to keep all of your current plants rather than just a few.>
Thanks for you advice, Steve Thornton MD
<You’re welcome, Ronni>
Re: Black Fur Algae (Cyanobacteria in a planted aquarium)
I have been reading the faq's on algae control and still don't see a
specific answer to getting rid of "black fur algae". This
stuff started appearing on my 40 gal freshwater tank about 2 months ago and now
is blooming on all my broad leaf plants as well as the surrounding rocks. I
am very careful on feeding quantities ( mostly flakes twice daily and occasional
frozen brine).
I would really like to get this under control. It isn't all that unattractive in
limited amounts but it's obvious that it's currently out of control. I
am reducing the amount of light daily and only feeding flake food currently.
Please advise with specifics if you can it would be greatly appreciated. Thanks,
Bud Palmer

<Please read here: http://www.wetwebmedia.com/PlantedTksSubWebIndex/algcontags.htm

- Who's going to eat my dead plants? -
Hey guys, hope you had a good holiday:)
<It was lovely, thanks for asking. JasonC here...>
I am have been looking for, but haven't really been able to find much info on
fish, that will eat dead plant material. I have a school of 7 Cory
cats, but I'm not sure they are eating dead plant or if they are more of a
carnivorous fish. Currently I have about 20 tetras, 3 striped Danios,
7 Corys, 4 otos (plan to get more of all cept Danios soon) and, a guppy who
LOVES to eat off the bottom, the thing is HUGE and fat for a guppy! But
they are rabbits and I don't want to add a 2nd cause I don't want 200 fish in
the tank, at least not guppies:) The tank is coming along
really nice. Some plants aren't doing so well and I'm not sure why,
others are thriving incredibly. I'm still working on getting the
setup finalized, I changed to a Reverse UGF the other day to replace the 300gph
x 2 powerheads I had. The only immediate result was the loss of 1
Cory cat (leaving me with 7) and 1 tetra with ick. Don't plan
to treat or anything, I expect it to clear up soon. <I wouldn't 'expect' that
- ich is a parasitic disease and can easily grow to epidemic proportions.> The
day after I added some substrate fertilizers I saw dark algae growth and access
material stuck to the uplift tube, thus the change. Anyways, I
understand barbs are ok at eating algae? <That's right.> Would they eat
dead plants? <Probably.> A small school of cherry barbs may look nice. Open
to any suggestions if you can think of any fish that may shine in this tank and
also any that may assist in eating detritus as the guppy does. I plan
to add about 6 or 7 more Corys, and about 10 more otos, and a SAE or 2 if I can
find one! <Just be careful as the total number of fish increase in this tank,
your high bioload will also drive the algae production.> Tank is a 75 gallon,
0 ammonia and nitrite, PH at 7.0 even (thx DIY CO2).
Thanks as always!

Algae Control, Testing the Water
Greetings to: whoever isn't lucky enough to be out playing somewhere. =)
<It's still early Friday, there's time...>
As always, great site, I would still be in the dark ages if it weren't for you
guys. (Literally, now I have 220W from A-H supply). Setup is lights, Proquatics
canister filter (~160gph), 50gal rectangle (standard 48"). Use potassium
based water softener. Been having trouble w/ cloudy algae, and have lost most of
my livestock (which isn't much, sort of been starting over with the system).
Based on water test at my local trusted fish place, I have elevated nitrates.
Been adding Cycle bacteria starter at 1/3rd vol water changes every other day,
and been adding an algae coagulant. After 5 days my livestock seem to have
stabilized (haven't lost more) but the algae doesn't seem to be getting under
control.
<Test your source water for ammonia/nitrites/nitrates. Filter the water of
any of these pollutants before you add them to your tank. Additives are a poor
second to water treatment (RO/DI) Vacuum all waste thoroughly from substrate and
stop additives. Clean canister and media in old tank water often to prevent
nitrate build-up. It's the nitrate causing the algae bloom.>
I guess I have several questions: What sort of water testing kits do you like
vs. which ones should be avoided (is it worth it to blow $200+ on a LaMotte
kit?).
<The best ones for FW are the least expensive tests that have color samples
you can actually match. This is an individual thing. The WetWebMedia.com
sponsors have test kits that are not so expensive. I've used "Doc
Wellfish" for amm/nitrite/nitrate and hey worked just fine. They don't have
to be expensive, especially for fresh water.>
At what point is it necessary to do a complete tear down (judgment call I
suppose, but is there a rule of thumb), and how do I sterilize the system to
remove all the algae if I ultimately have to do a teardown?
<This would be a mistake. The bacteria, flora and fauna you need to process
the same wastes the algae use would be killed. You don't want that, you want to
export your wastes and prevent them from being introduced. Either the nitrate is
coming from wastes or it's coming from your source water. Eliminate these and
you will eliminate your algae.>
I realize with proper biological balance and cleaning algae shouldn't be a
problem, but is there value added in using UV sterilization on a freshwater
aquarium garden vs. dangers vs.
cost?
<Not necessarily. It's easier to deal with the underlying problem,
nitrates.>
Also, I hope to convert/upgrade to a reef setup at some time (right now need to
learn enough to get this system under control), but was disappointed to learn
canister filters aren't a good idea for such systems. Its too late now, but are
protein skimmers good choices for freshwater planted systems?
<They are fine for carbon use in reef systems. Nope, for SW they work great
though.>
I was hoping I was buying mostly stuff that could be pressed into use in a ~150
gal reef system someday.... Live, learn, spend $$. =)Regards, Nate
<So far, so good. Craig>
vacuuming gravel
Hello,
<<Hi Leslie, Craig at your service>>
The other day, I was doing a partial water change on my freshwater aquarium (I
have a power filter on the outside). Normally, I just poke the surface of the
gravel to pick up the waste products. This time, however, I accidentally pushed
the gravel vacuumer (don't know if this is the right term) all the way through
the gravel (but not through the glass). I was shocked to see the amount of
debris I vacuumed up.
<<I'll bet!>>
Should I be inserting the vacuumer all the way through the gravel normally? This
would be rather inconvenient since I have a lot of plants, but I figure I should
be getting rid of as much waste as possible. Thanks, Leslie
<<Absolutely vacuum as much of this as you can down to the glass. Be
cautious around your plants so you don't harm the root system which can spread
and be rather extensive. If this is the case be careful with the vacuum tube and
let the siphon do the work. This will use a lot of water at first, but this is
good since this waste has been building up. Happy housekeeping! Craig>>
cloudy freshwater (planted tank... new)
Good afternoon everyone,
<Howdy>
I've recently started a 55 gal freshwater planted tank. The tank has been set up for about 4 weeks, it's running with a emperor 400 bio-wheel , and an
Ebo-Jager 100 with temp remaining at 76deg and 110w pc daylight.
I've planted the tank with 1 Anubias barteri, 6 bunches of Alternanthera reineckii, 6 bunches of Ludwigia repens,2 Microsorium pteropus and 8
Amazon swords, 1 spadeleaf swordplant (Echinodorus cordifolius).
I had decided to return the barbs that I had (only two) and attempt a tetra tank. So I did some research on cardinals and did some research and first thing I did was to lower my GH from 7 to 3 using a softening pillow.
<Mmm, this is a lot of change... changing in a short time... I would have and now would leave the tank alone for another month or so to "settle in">
After using this it clouded my water and raised the ph to 8. What I'm wondering is if this is a direct result from filtering with this pillow and what I can do to bring the ph back down.
<These are related events... and I would just let time go by... the pH will drift down with the aging/acidification of your system... with use of some of its present buffering capacity>
My water is also cloudy and has been since the day after I put the pillow in, I've since taken it out. Will my water clear up on it's own or will I need to do a water change?
<It will clear on its own... and I would leave out the pillow and not use chemical filtrants. Please do read through our Planted Tanks
Subweb:
http://www.wetwebmedia.com/PlantedTksSubWebIndex/AquariumGardenSubWebIndex.html and the link to "the krib" re planted systems... with a little more knowledge and practice you'll do fine. Bob Fenner>
thanks
