I have a 40 gallon tank powered by a penguin 330 bio-wheel and a cpr bak pak protein skimmer.I have a coral beauty and a flame hawk. I noticed some spots on the coral beauty.My guess is ick. It is a fish only tank so I can use copper. My question is what is the proper copper level to cure ick? I heard 1.5.And how long must I mantain that level?Also can I leave my protein skimmer on?
