Review on 🐟 Seachem Cupramine Copper-250ml by Travis Varner

Used with the SeaChem copper test kit which is a must have. I've had ichthyophthyriasis in my saltwater farming system and after losing a few dozen fish I finally realized they were afflicted with it, which was the first time I've had saltwater systems in 20 years. I was lucky never to have them, but there are so many fish in this system it had to happen. Dosed no more than me for two weeks!
