Hi. My angel fish is still doing O.K. I named he/she munchy because he/she is always looking for food. Anyway, my nitrites are still just at tolerable levels. Any suggestions? I bought one of those water softener pillows because my water hardness is pretty high on the GH and KH tests. Should that help things any as far as nitrites go? I have found lots of articles on this but they are all a little different. I think I may do another partial water change. Could the partial water changes be affecting my cycle?
