So, my qt tank is fine, but my main tank has ich. In the tank is live rock and all those little things, one hermit....have not seen in two weeks, on large snail, one camelback shrimp and one scallop. NO fish. So I want to try and ris the ich out of the system 100% and I know copper is a bad thing? Anyway, what would you guys suggest. Don't want a uv setup. Was really trying to see if the solutions they sell would work or not. 75 Gallon about a third of live rock and live sand, no corals.
