hello all. i have a problem in my reef tank and im looking for some help. i just noticed that my tang and 2 clowns have ich. this is the first time i have had ich in my saltwater tank. the tanks been up for 5 months and everything has gone smoothly until now. i have heard that you can not use cooper meds because of the inverts and corals. i have some shrimp, hermit crabs, snails and a horseshoe crap. i also have some big mushrooms and corals. anyone know what the best medication to use would be. i just bumped up the heater to raise the temp a couple degrees. any help any one can give would be greatly appreciated!!! thank you
