I have a 55 gallon tank that's been running for about 2 and a half months now. Currently have 6 rummy nose tetras, 2 angelfish, 4 dwarf gouramis and a bala shark. For the last month and a half my readings have been pretty consistent at 0.25 ammonia, 0 nitrite and nitrate 10. The nitrate goes down to 5 typically a few hours after a water change which I've been doing every 4 or 5 days. Just wondering why my ammonia and nitrate have yet to come down to 0. My nitrite has been 0 for the last month and a half.
Thanks
