Review on 🐟 Seachem Cupramine Copper-250ml by Robert Petrig

I use this product extensively in my marine aquarium quarantine system for all new fish. I haven't had to treat an active case of Ich yet, so I can't comment on how well this actually works, but it's a standard copper-based remedy. All of the fish I have treated with this product have been exceptionally healthy with no side effects from the treatment. I find that actively using it in quarantine is a surefire way to prevent an I-case on your main system.
