We recently got a 75 gallon tank that came with fish. We also have our own, but are trying to find new homes for many of them due to fear of over population. We have had the tank for about 2 weeks now. We have done a complete water change obviously when we first got the tank, and at least 3 partial water changes since.

I test the water often, and have put in things to lower pH, ammonia, nitrates, nitrites, and produce bacteria for the filter. Don't get me wrong, I haven't put tons of chemicals in, just the ones to maintain the levels. I'm pretty sure the filter is not completely cycled yet, as there is still a small odor from the tank.

I've increased oxygen flow, reduced feeding and regulated temperature. My question is: Why are my bottom feeders still having rapid gill movement, and some fish hug the top of the tank at times (Not constantly) as if gasping for breath? I know these are signs associated with nitrite poisoning, but I watch the levels and can only use so many chemicals before I wonder why they aren't working.

Is it just that my filter has to finish cycling? Or is there something else I could do to aide to my fish?? I hate to see them seeming as if they're unhappy, and I just want them to be happy! The levels when I checked today are: 0.0 Ammonia, 0.5 PPM nitrite, 30 ppm nitrate, ph 7.2. Any ideas?

Hello Kieshyiah
and welcome to fishlore! It sounds like you are trying to do everything right by your fish in your new tank. Sometimes adjusting the Ph with chemicals can have an adverse effect. What is your normal Ph and why are you trying to lower it? Most fish can live in a wide range of Ph levels from 6.6-8 easily.
They may still be effected by your nitrite and nitrate readings and I would continue to do daily water changes til your tank cycles.
what are the types of fish you have and how many?
