I had posted previously about a 3 gal betta tank that i was struggling to cycle because I had 1ppm ammonia in my tap. That tank finally cycled but my cats wouldn't leave it alone and kept falling in it. I finally freed up my 5gal tank and transferred him to that with his sponge filter. I think I've completely lost the cycle again.. My tap water now has almost 2ppm ammonia. I test daily and only once in the last 3 weeks have I had any reading of nitrites. That was a few days after transferring everything. Out of desperation I switched his sponge filter with one from another betta tank. It made no change in either tank. The 5gal numbers didn't change and I didn't lose the cycle in the other tank.......that really confuses me. I didn't test the 5gal yesterday because I wasn't home. I checked it today and got the highest ammonia reading ever of 2ppm. Changing the water doesn't help much since I'm adding about the same amount of ammonia back in. I use prime with almost every water change but occasionally will just use dechlorinator in hopes that maybe by leaving the ammonia alone it might help the cycle along. I use stability daily even if I don't change water if the ammonia is under 1ppm. I do see very little nitrates on occasion. Temp is kept at 80 and I do run the really crappy mechanical filter that came with the tank just to get more circulation Any thoughts on what else I should do?
