8 week with your main tank fishless should have killed all the ich in the main tank. But if the copper treatment didn't actually kill the ich on the fish while in the QT, then that would be how it got back into your main. While copper treatments will definitely kill the parasite, keeping the copper levels at the appropriate levels, for the correct amount of time, is where that treatment seems to run into problems.
