I’m going to QT all my fish. I have Copper Power and a Hanna Copper tester. My plan is to build up the copper to 2.0 (maybe 2.25?) for 15 days, minimum. I don’t have a second QT tank, but I do have a large tote (38 gallons) that I could place the fish in while I sanitize the QT tank. How long would it take to completely sanitizing the tank? I would like to think a few days in the tote wouldn’t be bad as long as it was heated and had a sponge and air stone (minimum). That would minimize the amount of additional equipment I have to purchase, plus help keep my spouse happy. Any reason this wouldn’t work?
