I'm with you. Treating a pair of rhomboids right now along with the rest of my fish from my DT that are infected. I've been following HumbleFish & melypr1985's advice and slowly raising the copper levels. I'm using chelated copper, CopperPower and have worked up to half dose over the last 2 days. No signs of stress from them, still very active and eat like beasts. Hopefully they'll handle the full dosage well as I continue to work my way up. Good luck on your QT process, I hope it goes well for you. I'd be interested in hearing which route you take, and the outcome. During my search I found a lot of questions with answers, but not many people seem to update with the outcome of the advice given.



Of course my reef tank is only running 44 years with no problems, but I think at 45 years, problems creep up.
