Not sure if this is in the right place but...Ok my problem. I have my 90 gallon holding tank that I have fish in until my 180 gallon cycles. BUT my 90 gallon ammonia is and has always been a problem. My problem is the fish came from a guy that was abusing them very badly and I ended up taking them but I took them to early and now my 90 ammonia is at 2.0!! I have been doing daily water changes of 50% and the ammonia problem isn't going away. Im scared to loose these fish and I need to get this under control. Its starting to scare me and getting very frustrating having to do 50% water changes everyday. I just want my tank to be healthy and this is a never ending battle. The fish have been in my 90 for about 2 weeks now. Up until yesterday I have been able to keep the ammonia level at about .50 which I know is not good but sure better than 1.0-2.0. Why is my filters not cycling and keeping up? I have a rena filstar xp3 and an aquaclear 110 running and nothing has been able to fix the problem. I have been adding some big als bio liquid but it doesn't seem to be doing anything. Sorry for the novel but I need help asap and my fish would appreciate it.
