Hello I got a fish tank about 4 weeks ago, and I have been doing a cycle with fish. The fish have been doing fine (Black Moore), and (Mollie). The ammonia and nitrite have been staying at one, and haven't dropped nor wen't up. I no this is not good for the fish, and I read that the ammonia should have dropped to 0 by now. What am I doing wrong, I have had to change the water a lot because of it. I even bought the ATM Colony bottle, and it's been a week with no affects.
