Review on 🐠 Fritz Mardel Coppersafe Aquarium Treatment - 4oz by Kristi Martinez

This product has successfully cured our rooster of moderate velvetiness. I continued the weekly 100% water change, adding Copper Safe plus Aquarium Salt after each water change and covering the tank with a dark towel. It took about 5-7 days to see the effects, but by day 14 there was no sign of velvetiness. Treated the water again after the signs of the disease had disappeared, as recommended on the packaging. Our fish are healthy and happy again!
