okay, i know that ideally my tank should always be at 0 ppm for ammonia. However, I have had my tank running for a year now and i do frequent water changes, plus vaccuuming (i used to have gravel, now i have sand) and my ammonia has always stayed at a consistent .25 ppm. my fish are healthy, and swim and have a good time, doesn't SEEM to bother them. the only reason I am concerned about it now is because I just had a really bad nitrate jump so i have been doing water changes every day. nitrates are now between 10 and 20, nitrites are at 0, and ammonia is still at .25. I am moving my fish to a 20 gal, hopefully today or tomorrow and I'm concerned that if the few fish i have cause ammonia to be at .25 in a 55 gal, what are they going to do to my 20 gal?!?!?! any ideas on why ammonia is up?
