Copper is the most effective way to treat ich period! Unfortunately its not reef safe. There is a product made by instant ocean called LifeGuard which is supposed to cure ich. I am currently using this on my new Powder Blue Tang which broke out with ich in my QT tank. It seems to have cleared the ich with no ill effects.
One thing that is a must when using copper is that you must get an appropriate copper test kit and measure levels daily. Too high and it will kill your fish. Too low and it wont kill the ich. _________ 75g reef with Nova Extreme 8 bulb HO T-5 lighting, refuge, Remora skimmer, DSB, Seio powerheads, Acro's, LPS corals, assorted zoo's & mushrooms, Yellow Tang, Maroon Clown, Blue Cleaner Goby , Cleaner, Fire and Sexy Shrimp, Coco Worm, T.Crocea Clam, Derasa Clam
