OK, I had an out break of ich in my tank and Ive been treating the tank with this med that the LFS gave me also Ive been feeding garlic extreme on brine shrimp,flakes and Sea weed. My purple tang has recovered completely but my two clowns are still scratching. Is it possible for me to beat the ich with this treatment or do i Have to remove them from the tank? Also ive quarentined my percula clown for 3 weeks now with copper(looks great), But if i add him to the tank hes just gonna get sick again right? Any reccomendations?
