Hi everyone, has anyone treated their qt with both copper safe (not ionic copper) at therapeutic level (>2.0 ppm) and formalin (25 ppm/day) at the same time to treat both velvet/ich and brookynella? I’ve been consulting with Jay Hemdal about my current situation, and he said he has not tried copper safe (chelated copper) with formalin, so he can’t recommend it. He said ionic copper with formalin is fine, but I’m using copper safe, because I have more sensitive fish that might not handle ionic copper well. I have full respect for Jay’s opinions and experience and am definitely cautious about combining the two meds given his advice. However, I’m wondering if anyone might have tried copper safe and formalin together successfully. I have some sick fish that we’ve been struggling to diagnose. They have seemed to show improvement with the copper safe. However, we’re still seeing some symptoms that could be Brookynella. I am concerned about removing them for a formalin bath, as moving them has proven to really stress them out and has already killed several fish. Thanks for your help.
