Mbuna and Ammonia Problems
7/7/08
Hi there. Wondering if you may make a couple of suggestions regarding
filtration, etc.
<Sure thing!>
A number of months ago, I read Ad Koning's book on African Cichlids. Since I was
experiencing ammonia levels in my 55 Mbuna tank, I followed his advice and fed
the fish once every other day (vs. 2-3 times per day). This brought on a great
deal of aggression and I lost a lot of fish. So I went back to feeding them
twice per day - an amount they can consume within 30 seconds.
<I have to say I agree with your experience. Whilst in theory feeding fish less
than once per day may have distinct advantages, on balance I'm in favour of the
"multiple small meals" approach. All my day-active fish get two meals per day,
but small ones. One in the morning, another in the evening. The catfish get
their pellets or wafers at night, after lights are out. This way you spread out
the ammonia and problems with uneaten food.>
I then commenced doing 10% water changes every other day which did nothing to
abate the ammonia levels.
<Ah; well, if you're getting ammonia present "in real time", then there's three
things to consider -- overfeeding, under-filtering, or overstocking.>
I am back to conducting 30-40% water changes on Saturdays. Despite taking
ammonia tests, which show no trace of ammonia, a few of the fish still flash.
I've been treating the water with Amquel which neutralizes ammonia and I have
found this effective. I also have a canister and a large hang on filter equipped
with ammo chips. I change the filter media once per month (not at the same time
intervals).
<Chemical ammonia removers only work up to a point, and once a dose has been
used up, any new ammonia produced by the fish is left untreated. Amquel is of no
value at all in this context; it is exclusively for removing ammonia from tap
water prior to adding fish.>
I understand bio media aid in the nitrification process. Both filters are loaded
with the stuff.
What to do? I must be doing something wrong?
<As outlined above. Given the tendency for Mbuna tanks to be overstocked,
filtration has to be profound. I'd reckon on a big canister filter at least 6
times and ideally somewhere between 8-10 times the volume of the tank in
turnover per hour. So adding a second big canister might be just the ticket.>
Look forward to hearing from you.

<Hope this helps, Neale.>
Re: Mbuna and Ammonia Problems
7/9/08
Hi Neale, thanks so much. With both filters (canister and hang on) I'm
turning over an equivalent of 685 gph which meets the needs of the 55 gallon
tank. The canister is only filtering 185 gph which is rather weak. Looks like I
need to seriously upgrade the canister. What about media Neale? Is zeolite
effective if changed/recharged once per month? What do you use to combat ammonia
levels and spikes?
Thank you very much! Lisa.
<Hi Lisa. The problem with combining multiple "weak" filters on a single big
aquarium is that unless you position their inlets and outlets carefully, it is
very easy to end up with corners of the tank with minimal water movement. Adding
powerheads can help, as will an undergravel filter. But in all honesty, with
fish are big and messy as Mbuna, filtration needs to be robust. If you are
detecting ammonia, then you clearly don't have enough biological filtration. I
wouldn't bother with zeolite -- realistically this will be very expensive, and
removing some biological filtration media from one filter to replace it with
zeolite makes no practical sense at all. So, what I'd look at is something like
a couple of Eheim 2217 'classic' filters. These aren't expensive, have lots of
capacity for biological media, and are extremely reliable. At about 260 gallons
per hour turnover, two of them would give you well over 10 times the volume of
the tank in turnover per hour. You could of course simply add one and use that
alongside what you already have, or combine one filter with a reverse-flow
undergravel filter that would take care of carbonate hardness as well as
ammonia. While old school, reverse-flow undergravel filters are inexpensive to
set up and extremely effective at dealing with ammonia and solid waste. Either
way, fill with good quality ceramic media or sponge for biological filtration.
That should take care of your ammonia. In properly maintained, mature aquaria
with suitably sized filters, you shouldn't get ammonia spikes or problems. It's
as simple as this: if you detect ammonia, you either have too many fish for your
filtration system; put too much food in the system for the filter to deal with;
or just don't have enough filtration for the overall bioload. Cheers, Neale.>
Re: Mbuna and Ammonia Problems
7/9/08
This is great info - thank you so much! My problem has to be poor filtration - I
only have about a dozen Mbuna in the 55 gallon so I'm not overstocked. I'll swap
my current canister for the Eheim 2217. Thank you!
<Hi Lisa. The concept of "being overstocked" is a practical rather than
theoretical one, which is why I am leery of these inches-per-gallon rules. If
you have a system where ammonia never gets to zero, you're overstocked. As you
say, on paper at least a dozen 10-15 cm Mbuna should comfortably fit into a 55
gallon system. But in practise these fish are so active and have such high
growth rates that it is very easy to find the otherwise reasonably sized filter
being overwhelmed. I have a 40 gallon system in which I keep a few smallish
tetras and glassfish along with a 15 cm Panaque nigrolineatus. Although water
quality is perfect, the tank itself gets dirty very quickly simply because the
catfish eats wood and produces masses of brown faeces. So it has two canister
filters offering water turnover of almost 10 times per hour. Seems ridiculously
over-filtered on paper, but actually the least I can get away with! In other
words, one should go by empirical data -- ammonia tests for example -- rather
than what is stated on the box the filter came in. Cheers, Neale.>

Water problems... ammonia, cycling, treating
tap... – 6/11/08
Hi!
<Hello,>
I bought a 20 gallon aquarium about a month ago. I put some fancy goldfish in it
to try and help cycle it.
<It's a lot easier (and nicer on the fish) to use a "fishless method". The best
of these is merely to grab some filter media from one aquarium and stick in in
the new aquarium's filter.>
About 3 weeks into owning it I ran into an ammonia problem (obviously part of
the cycling process I take it). I started frequent water changes (every day)
because the ammonia level was in the stress-harmful zone (lost a fish).
<Yes, ammonia is likely the problem here. There are commercial products that can
jump-start the filter by adding live bacteria. The most popular seems to be Bio
Spira, though I admit to never having used any of them. I prefer to "seed"
filters using media from other tanks. 100% effective, zero cost!>
My question is this ...my tap water even after conditioning it with
dechlorinator is still in the safe range but not ideal.
<Meaning what? It has ammonia? First thing -- there is no "safe" level of
ammonia; it's like being pregnant, it's a binary state sort of thing. So, you
either have zero ammonia in the water (which is good) or not zero ammonia (which
is bad). Some water supplies do contain traces of ammonia, which can be fixed
using products like Ammo Lock or even many dechlorinators. Secondly, do remember
that if you use some (older formulation) dechlorinators on tap water that
contains chloramine rather than chlorine, you actually *make* ammonia.>
Obviously, when doing a partial water change the ammonia level goes up after a
couple days because the tap water isn't ideal to begin with.
<Hmm... the quantity of ammonia in new tap water should be zero or very low; if
the ammonia concentration goes up or at least fails to go down, then the problem
is more about lack of filtration, overfeeding, or both.>
Any ideas of what to do to remedy this problem (without buying expensive bottled
water)?
<Tap water, particularly hard, alkaline tap water, is ideal for Goldfish. Use an
ammonia-neutralizing conditioner on all new water, and that should take care of
the small (typically less than 0.5 mg/l) ammonia in the tap water. Your job now
becomes ensuring the filter system handles the ammonia produced by the fish.>
I was thinking to try a double dose of the dechlorinator? Currently I am using
"AquaSafe" (1 teaspoon to every ten gallons)
<Not familiar with the brand. In any case, use the dose as indicated on the
package. If it says it neutralises ammonia, then fine. If not, you'll need to
switch to (or supplement with) another conditioner that neutralises the ammonia
in tap water. Understand this: no "ammonia removing" conditioner will do
ANYTHING about the ammonia produced by your fish. As far as you're concerned,
these are utterly different issues.>
Any advice you could give me will be greatly appreciated as I would like to get
away from changing water every other day
<I understand. First, make sure you're treating new water correctly to remove
tap water ammonia. Secondly, review filtration/feeding to see if the ammonia
produced by the fish is excessive. Do have a read of the 'setting up' articles
we've got here at WWM, perhaps starting with these:
http://www.wetwebmedia.com/FWSubWebIndex/fwset-up.htm
http://www.wetwebmedia.com/FWSubWebIndex/fwfiltration.htm
Cheers, Neale.>
Re: Water problems
6/13/08
Thanks for the informative advice!
<You're welcome.>
I went today and bought a larger filter instead of the 10-20 I bought a 20-40
Ammonia levels dropped almost immediately after I put on new filter and changed
water.
<Very good.>
One fish has ammonia scars on his little tail (not bad I've seen way worse) He
keeps flashing around tank. Anything I can give him that will ease him?
<Treat for Finrot. He'll recover. Provided the damage is superficial and limited
to the fin membrane rather than the body, fish tend to recover quite well.>
Thanks
Oh, also the tank I have I bought at a garage sale for a buck and it seems to be
a homemade one as it is much taller than wide (not like in stores). The tube
from filter doesn’t really go down to the middle of the tank. Any Ideas on how
to extend it?
<What sort of filter is this? One of those hang-on-the-back ones? Not sure they
can be adjusted as you suggest. This does cause a problem that the bottom layer
of water could be relatively stagnant. Adding an airstone would help, or even
another little submersible electric filter or air-powered sponge filter placed
closer to the bottom of the tank.>
I checked with PetCo and they sell nothing. I was thinking maybe a piece of
plastic tubing from Menards to attach? Could that have been one of the problems?
(The tube goes down around a foot and a half) about 3-4 inches from middle of
tank)
<Well, it could help. But the pump mechanism might not work so well if the inlet
is located that much further away from the impeller. I'm not an engineer though
so can't comment with any authority here! Cheers, Neale.>

Chronic Ammonia? 5/10/08
Hey y'all,
Love the site, it has helped me more times than I can count. This is my first
time writing in as I cannot find the answer anywhere else. I have had my fresh
water aquarium up and running now for about three months. At this time It
contains a silver arowana- 8in, a clown knife- 8in, a jewel cichlid- 3in, a
common pleco- 4in, and two crayfish. My dilemma is that the ammonia has
registered around 4 ppm for about a month now. I figured the test may have
gotten old so I replaced it with a new one and the readings are still around
4ppm. Now for the puzzling part: My Nitrites have consistently been at zero
since the cycle finished, my Nitrates are around 10ppm consistently, I do
bi-monthly water changes of 25%, I do not overfeed my fish, my aquarium is bare
bottom, and no one in the tank exhibits labored breathing, scratching, or any
other stressful behavior. As I monitored the cycle the ammonia spiked (as it
should), and never dropped below 1 ppm. Then I noticed in the months that
followed the ammonia would not drop. Now it has apparently skyrocketed to 4 ppm
just in the last month as I said. Could there be an inhibitor for the ammonia
eating bacteria, or could there be something in my aquarium giving me false
positives? I would have to assume that if my ammonia was really this high for
any length of time my fish would at the very least be acting funny, and my
crayfish would definitely be dead. Any suggestions or advice would be greatly
appreciated.
Regards
James
<Hi James. As you seem to understand anyway, ammonia comes primarily from the
fish, either as an excretory product or else because of the decay of uneaten
food. So you could review your filtration and consider whether an upgrade (or
perhaps a service) is in order. For fish of the type you're keeping, I'd be
recommending turnover rates of 8-10 times the volume of the tank. Things like
carbon are (in my opinion) a waste of filtration space, so removing carbon the
make space for more biological media may be in order. Water changes of 50%
weekly would also be recommended for this type of system, but that's not really
relevant to this particular problem. More important might be the size of the
tank: unless the tank is fundamentally big enough (in terms of volume) to dilute
the ammonia the fish produce, the combination of a too-small tank with too-weak
filtration system can result in persistent levels of ammonia. Or put more
simply, the filter never gets enough time to remove the ammonia in the system,
and the tank isn't big enough to dilute what remains. For these types of fish,
the aquarium will need to be 750 l/200 gal in size once the fish are adult,
though juveniles might get away with a somewhat smaller system. Now, the other
issue is servicing the filter. Filters need a certain amount of care, in
particular cleaning. Removing the filter media for a rinse is fine, but some
folks overdo this and end up killing the filter bacteria. Conversely, if the
filter gets clogged, the lack of oxygen lets the bacteria die as well. One last
consideration is your water. Some water supplies come with a certain amount of
ammonia; others are treated with chloramine, and this can split into chlorine
and ammonia when treated with traditional dechlorinator. So test your tap water.
Cheers, Neale.>
Problems with ammonia, Goldfish in too
small a world, reading 4/28/08
I have two fancy goldfish who are currently living in a 10 gallon aquarium.
<Stop! This is the real problem... Need more room than this...>
I am now aware that ten gallons is not sufficient and I am looking into
upgrading to 30 gallons, hopefully in the near future. In the meantime, I am
trying to cycle my tank
<!? Fish should not be present during>
and I am very concerned about the ammonia levels.
Unfortunately, I did not know about cycling ahead of time.
<Take the fish back>
The pet store did a quick water test of my two day old aquarium water and said I
was "good to go." I knew that a biological filter would have to develop, but I
thought it was OK to do that with the fish in there.
<No>
I didn't know how hard it would be on them and that I would have such trouble
addressing the issues with ammonia. Regardless, I now have two adorable fish
looking to me to provide a safe environment for them. I added the two small
goldfish (one Oranda, one Ryukin) 17 days ago and I have been trying to keep the
ammonia levels down by doing daily partial water changes of 25 to 40%.
<Mmm... the changing of water will forestall the establishment of cycling>
This does not seem to be providing adequate relief from the ammonia, however,
and the tank does not seem to be cycling yet (Nitrates and Nitrites are both at
zero and the ammonia does not decrease significantly). I am extremely concerned
for my fish. I just can't get the ammonia down to an acceptable level.
Today, I placed them temporarily in a fishbowl with water that is similar to
what they have in the tank (regarding temperature, pH, etc.) just to give them
some relief from the ammonia while the aquarium cycles.
<Won't work either>
I plan to change the water daily (at least partially) and closely monitor
ammonia. At least I can change the water in the fish bowl and let their aquarium
cycle without them. I just could never get the ammonia down to zero in the
aquarium. Is this OK? How long can they stay in the fish bowl? I just want them
to be somewhere safe while their home undergoes all the ammonia and Nitrite,
etc. spikes. I want them to go back in as soon as the aquarium water is safe for
them. Please help. I love these little guys
<Then return them temporarily... use a real cycling product or other means...
see below>
and I know a fish bowl is not where they should be but I don't know what else to
do.
Thank you so much.
Sincerely,
Laurie

HIGH AMMONIA >>> EMERGENCY
PLS HELP!
Hello, i will start off by saying that i have a 60gal freshwater tank which
has been up n running for about 2 1/2mo now ... i have 14 1" baby piranhas, 1 3"
Pleco, and 1 3" black lobster ... i have about 10 live plants and 2 whisper 60
filters (660gph total filtration) ...
<Not sure about mixing Piranhas with the other stuff, and obviously once these
fish get even more than 3" long, they will need a massively larger aquarium.>
My nitrites & nitrates are always at 0 (i would assume due to the live plants)
and my ammonia is always in an acceptable range.
<There is NO ACCEPTABLE AMMONIA RANGE. Let me be crystal clear about this! If
you can DETECT ammonia, you've got problems. Period. End of discussion. Piranhas
are notoriously sensitive to ammonia, and any exposure to the stuff is life
threatening.>
Well i tested my ammonia lvl one day and it was at 8.0, so i decided to clean
all my filters and get the gunk out of them, rinse/change my filter media, and i
also added 2 3"x8" bags of carbon/ammonia reducer pellets. I vacuumed my gravel
thoroughly twice and did a 50% water change. I did not find any type of dead
fish or decaying matter other than what was in the gravel. I also tested my tap
water and its ammonia reading was 0 ...
<If you have this much ammonia in the system, you have MAJOR problems. Let's
take this one step at a time. Carbon is neither here nor there, and in most
freshwater tanks is a waste of space. Anything carbon can do, 50% weekly water
changes can do better -- and without the need for the carbon to be replaced
every month. Or the risk of removing medications. Next up, ammonia remover is
irrelevant here. Ammonia remover is for fixing very specific situations, e.g.,
hospital tanks or breeding tanks. You'd need huge amounts of the stuff for fish
on a high-protein diet, and you'd also need to replacing it all every few days.
So don't waste your time with it. Finally, if you have no ammonia in the tap
water, but lots in the fish tank, it means only this: overstocking, overfeeding,
under-filtration. Pick and choose from these. Likely more than one.>
so after doing my water change, i tested it and my ammonia WAS STILL AT 8.0!!! i
don't get it at all ... and not to mention my water looks dirty and my water
smells???
<Almost certainly overfeeding and/or under-filtering.>
i took out all the deco fake trees and everything too ... i don't understand
what is causing such a large ammonia reading ESPECIALLY after doing a water
change and cleaning all the gunk out of my filters ... like i said i did not
find any decaying matter at all so i do not understand y after such a large
water change my ammonia is still high ... PLS HELP ME bc im goin nuts trying to
figure out what's going on!
Thx for your help, i look forward to your knowledge ... thx again!
<You need to [a] stop feeding; and [b] remove everything but
mechanical/biological media from the filters; and [c] insure those filters are
mature/adequate to the task at hand. Simple as that! Hope this helps, Neale.>
How to clear 0.5 Ammonia
Level? – 03/07/08
Hello,
My 20cm Flowerhorn who is in a 55-gallon tank has stopped eating and changed
swimming behaviour for a week. The pet store tested the water, everything is OK
except ammonia level (0.5) and I was recommended to clean and use Ammo Chips for
the filter . I did as recommended but today when the pet store tested again. the
ammonia level is the same without improvement. I usually change water every day,
about 1 gallon every 1 or 2 days to remove fish feces. I don't know how the tank
got that ammonia level. Please show me how to remove the ammonia or any
solutions to use for ammonia removal.
Thank you.
Sophie
<Greetings. Ammonia-removing chemicals won't work in a situation like this.
Ammonia-removers are designed either to remove ammonia from tap water or from
small, lightly stocked aquaria where biological filtration can't work. In your
case, the problems are one or more of these: overstocking, under-filtration, or
overfeeding. Pick and choose. I'd recommend a program of major water changes per
week, at least 50%. The filter needs to be providing at least 6 times the volume
of the aquarium in turnover per hour (i.e, the filter used in your tank needs a
turnover of not less than 6 x 55 = 330 gallons per hour). Reduce the amount of
food you are providing; fish need no more than they can eat in a couple of
minutes. Big fish only a need a single meal per day, and skipping a meal once a
week will do no harm at all. Lean towards green rather than meaty foods to
provide energy with less protein, as this will also help. If you fail to manage
the aquarium as I've described, this fish will soon be dead: cichlids have very
little tolerance for ammonia. Cheers, Neale.>
Guppies... hlth., use,
dis-use of ammonia removing tap/source water treatment products
02/29/2008
I'm sorry for being a nuisance but I wonder if you could give me a bit of
advice, I purchased 2 male guppies and 2 female guppies yesterday to go with the
other guppies in my tank but two of the males have since died, I checked the
water and found that the PH, Nitrate and Nitrite were smack on the correct
level, but the ammonia gave a reading of 8.0.
<Means one of two things. Firstly, the filter could be completely immature
(i.e., the fish produce ammonia, but not ammonia gets converted to nitrite, let
alone nitrate, so you detect zero nitrite and whatever nitrate level you have in
your tap water. Alternatively, you have a source of ammonia above and beyond
what the filter can cope with, e.g., ammonia in the tap water, or a lot of
decaying organic material. Either way, extremely bad news.>
I added some "Ammo Lock" to the water but when I checked it this morning it was
still high so I changed a third of the water and added some "Tap Safe" I have
just checked the water again and whereas all the other readings are correct, the
ammonia is still between 4.0 and 8.0 so I added some "Interpet Ammonia Remover"
<OK, you're misunderstanding what these Ammo Lock-type products do. They do not
remove ammonia produced by the fish or from decay. All they do is neutralise
small (typically less than 0.5 mg/l) amounts of ammonia that sometimes are found
in tap water. If your tap water has ammonia, then obviously adding it to an
aquarium would be bad, so these product render than ammonia harmless. What they
CANNOT do is remove masses of ammonia constantly being produced by livestock or
decay in the aquarium. If it was that easy we wouldn't bother with filters! So
put them away; they are as much help here as a bottle of mineral water would be
for putting out a forest fire. You need to establish why your aquarium is
generating ammonia (because it is). Review: stocking, feeding, filtration. Do
also check you are using the correct dechlorinator: if your local water supplier
uses chloramine, but you use a dechlorinator that doesn't treat chloramine, you
end up with a measure of ammonia in each bucket of treated water. Stop feeding
the fish, for a start. Check the filter is running and mature. Do 50% water
changes DAILY until things get down to normal. Ammonia is incredibly toxic to
fish, and anything above zero will kill them quickly.>
Do you have any suggestions on why all the readings are fine apart from the
ammonia.
<Outlined above.>
The other thing which puzzles me is that although the guppies have died, all the
other fish are thriving, including two very small molly fry which are between a
third and half the size of my neon tetras. Many thanks for your help.
<Hmm... fish that have been in deteriorating conditions will adapt (to a point)
whereas new stuff added from a clean tank to a dirty tank will just keel over
and die. But the short answer is if you have ammonia in the water, then chances
are all the fish will die.>
Regards, Gaynor
<Hope this helps, Neale.>
