I was not able to do fishless tank cycles. I have several 5 and 10gal tanks, all with 1 or 2 (divided) bettas, some live plants (about 1 plant per gallon in each tank), and no other fish or snails or anything. I do water changes rather constantly in all my 10 tanks to keep levels down. (About 10-50% 1-2 times per week depending on the tank and situation).
My question is, is there a way to cycle my tanks? I don't really ever let the ammonia get high enough to promote bacterial growth. But now that there are some live plants it's quite difficult to do water changes. Any suggestions?
