I have a 10 gal and I started it a little over a month ago. I used the water from my 55 gal to start it, but the problem is that I can not get the ammonia level below 4. the 55 tests show 0 but the 10 gal is giving me fits. I have done 25% water changes everyday then I went 25 every other day and then to every 3rd day and nothing seems to matter. I have a Whisper 5-15 filter and a UGF and am going to get a powerhead for the UGF. But I need to know what to do about the ammonia problem. Should I get a differant filter? I have ammino chips in the filter and ammonia filter media in the filter. What am I doing wrong????
