Hey guys, so unfortunately it seems like ich has struck down on me and ruined my downgrade so now I have to treat these poor fish. Does anyone know if I can use a large rubbermaid container to treat them rather than finding a tank to ruin just to use copper in it. I figured the rubbermaid could be used for something else once I'm done with the 3 month treatment process. I plan on using Seachem Cupramine to eradicate the ich. Any advice would be greatly appreciated. Thanks, Fortunato
