Hello everybody. I am setting up a new tank and my cycle doesn't seem to be
going so well. It's just a 10 gal tank and I put fish (2 small common
goldfish and a slightly bigger fantail) in it two weeks ago today (Tuesday).
The ammonia levels continue to rise, at last check last night was around 1.0
ppm (probably higher now). I did a partial water change on Saturday
(approx. 25%) and will do another 10-15% change tonight to try to help the
poor guys. My tank averages about 70 degrees, perhaps dropping a couple of
degrees at night.

I am not a seasoned veteran of tank set up yet but in my limited past
experience it has not taken this long for the ammonia level to drop. What
could be wrong? I have been putting in Hagen Cycle, a highly controversial
decision, I know. Should I continue regular small water changes to dilute
the ammonia or will fresh water all the time stress the fish as much as the
ammonia? I've already pretty much conceded that the fish will die, they
really don't look good (very lathargic, hiding in my decorations). I have
reduced feeding to a tiny pinch every other day so I know there is none
being wasted. Is this just a matter of me being impatient? The only real
difference I can think of between this situation and my past experience is
that the temperature may have been slightly warmer in my other tank setup -
I can't remember exactly, although I have never had a heated tank so the
difference would be minimal.

I would also like to extend my thanks to everyone who is so active on here.
Most often I have been able to answer my questions without posting just by
reading over past discussions. Hopefully someday I will be an expert and
able to offer my help to others in this group!

Hi David,

I'm new here but I'm going to jump right in. Your problem is you
strarted with to many fish. A ten gallon tank is small and goldfish
produce a lot of waste. One gold fish would have been more appropriate.


Here are some tips for cycling your tank.

1. Be patient! It can sometimes take up to 8 weeks for a tank to cycle.
2. Do not overfeed. Looks like your already on the right track here.
3. Do NOT do any water changes until the tank is fully cycled.

One last comment, goldfish are really a hit of miss. This includes the
fancy tails as well as the common feeder. Sometime they live forever,
sometimes they die right off.

The ammonia levels can take up to 20 days to peak and drop off. Then you
have the nitrite level to contend with. They usually start to peak after
the ammonia drops off, so from 20 - 40 days you get the peak and drop
for nitrites. Here's a link to a rather brief, but good explanation:

Have you tried to cycle with goldfish before? You have too many
goldfish to cycle a 10 gallon tank. (Or even to live there once they
start growing well.) I would have cycled with only one goldfish because
they put out so much ammonia and waste. Heat does increase the growth
rate of bacteria, but they do fine at 70F.

Generally, fresh water is NOT as stressful as ammonia. (If tank and tap
are reasonably matched, dechlorinated fresh water is not stressful at
all.) However, during a cycle when ammonia levels are high, a
moderately sized water change with alkaline tapwater can raise tank pH
and make the remaining ammonia more toxic. Sometimes tap water pH
changes after aerating overnight so try that if tank and tap don't match.

Stop adding the Cycle. It doesn't work very well and if you use it more
than once, it seems to make tanks cycle more slowly. (Bacterial
nutrients in the bottle maybe?) If you can find/afford it, BioSpira is
supposed to be a much better product.

The lethargy sounds like nitrite poisoning. Have you tested for
nitrites yet?

Add 1 teaspoon salt/gallon to the tank to help prevent nitrite poisoning
and help your fish recover from any diseases that might be causing the
lethargy. When you change water, you will need to add 1 tsp salt/gallon
to replacement water as well. I would also add a dose of Aquarisol
(copper). I find that new goldfish often have parasites that can be
killed by copper.

I am surprised to hear that I have too many fish. I have cycled a tank with
one small fantail before and it went reasonably well. I have always lived
by the "one inch of fish per gallon" rule and I am certainly under that
limit now, probably in the 4-5 inch range for my 10 gallon tank. I have not
tested for nitrite yet - I didn't think there would be much point yet. My
reasoning is that continually rising ammonia levels should be evidence that
nitrite producing bacteria have not yet colonized the tank, is that correct?

I have gotten several recommendations for BioSpira over Cycle, and I will
switch to that. Also I have been putting salt in the aquarium. Do I need
to do this repeatedly or just one initial dose, then replace with water
changes?

Assuming the fish die (let's hope not but I must prepare for the worst) will
the tank have enough organic material to finish the cycle itself or will I
immediately need to add more fish? If I could let the cycle finish on its
own I would not have to put anymore fish through the stress.

Thanks again for all the help!
