I have been fishless cycling now for over 2 months. I had a ph & kh problem and added crushed coral to my tank. I have been burning through ammonia but have been stuck with really high nitrites for several weeks now. My question is does anyone know what effect crushed coral could have on my nitrite test reading?? Or any idea as to why after I have done two large water changes (for lack of knowing what else to do) in a week my nitrites would still be around 5ppm. Before the first water change my nitrites were so high they weren't even reading on the test result sheet. I have absolutely no idea what to do at this point. Am I so messed up that I just need to start over with the cycle???
Any suggestions would be greatly appreciated.
