So, yesterday I was feeding my P's an I knoticed my tank had a small leak. I only had the tank for a month or so. I called up petsmart were I bought the tank an I returned it for store credit. They didnt have the bowfront that I have had. So I got a 40 breeder. I put the gravel and 25 percent old water in there. Is this gonna make my tank have to cycle again? It was running over night but I put my P's in a 10 gal. feeder tank. They slaughtered 6 of the feeders over night. Think its safe to put them in the new tank?
