i have some bad ich in my tank and I'm going to be moving my coral to my qt so I can get rid of this ich once and for all. If i treat the tank w copper(wanting to do copper not hypo), am I to think that all the coral will die after treating w copper and returning carbon into the filter sys and waiting until the copper doesn't show up on a test? Or are they that sensitive to trace amts. I was planning on keeping some LR in the dt as I dont have room for it all in the qt. Will copper just adere to that LR and screw up the coral once I return it? Thanks
