i have 29 gallon eclipse system that was given to me by a friend. i started it a month and a half ago and added a couple loaches to the existing fish. i think the loaches brought ich into the tank so i started using copper safe to get rid of the ich, took out the carbon filter but left the bio-wheel in. its been almost 3 weeks and i think the ich is gone but im gonna keep medicating the tank for another week or so. my question is...will the copper safe damage the bio-wheel?
