Hi all, after a 75 day fallow and cupramine treatment in hospital tank (.5ppm) ich has come back after reintroducing my fish. I got ich in the tank when I bought my hippo tang and my kole tang has also been breaking out. Was my fallow not long enough? I made sure not to transfer any water of wet equipment between tanks. I do not want to get rid of the hippo tang unless its the only way to end ich. Planning on doing another fallow and cupramine treatment. Any help would be greatly appreciated.
