I'm new to forums(old fart) and I hope this is the proper way to post. I have Ich in my tank and presently doing hypo-salinity at 1.010. I wanted to know if I can also use Seachem Cupramine medication at the same time, or is this stressing fish too much. I have FOWLR. When I was much younger I lost an entire tank to ich. The second time I saved the tank by composting the affected fish to save the tank, which worked, but can't afford to loose a Powder Blue Tang. Please help, and thanks in advance!
