I have a male betta, Comet, in a 10 gallon hospital tank since he has fin rot. While his tank was once cycled, he get a new filter so he doesn't have enough bacteria to support a full cycle. His ammonia is at 0.02ppm and I can't get it down. My tap water has about 0.05ppm ammonia so water changes only make the problem worse. Adding ammonia lock or prime won't work because there isn't enough of a cycle to get rid of the less toxic form of ammonia before it converts back.
His fin rot is getting bad fast so I put some triple sulfa in today. It might not work though since he still has ammonia in his water. I need to get that out really soon so the meds can have a chance of working. Comet's other water parameters are pretty good so the ammonia is my only really big problem. I put some TopFin ammonia remover in today to lessen the effects of the ammonia so the medicine can have a better chance. What can I do to get the ammonia out of my tank fast?
Should I add ammonia remover every day? I'm worried this is bad for my betta and could hurt him in the long run. Also the medicine requires a water change in 2 days, so what should I do to get the ammonia out of my tap water. Is there any kind of filter or something I can get that eliminates tap water ammonia. I really need help so please reply fast. Thanks
