I've been cycling my 55 for close to a month . About a week or so ago the nitrites appeared off the charts. One week later and the test still shows a neon purple color right when the drops are in. I did a 45% water change because I heard high nitrites can stall a cycle and nitrites are STILL unreadable! Any recommendations? Do I just have to wait, or am I looking at a lot of water changes? Also, should I still be dosing ammonia? I know that I shouldn't starve the bacteria, but I don't want to add any more nitrites. I also have nitrate reading, if that adds anything.
