If the ick life cycle can last up to 76 days then why do we only treat copper for 30 days. I literally had 3 fails in QT and had to break my tank down twice to catch fish. On all 3 times ick returned a few weeks after copper treatment. I am using CP now and the tineframe is even less. Does CP kill all stages or something?
