Copper works when dosed correctly
Copper sulfate is a heavy metal that when dosed correctly, kills Chilodonella. The idea is to kill the parasite and not harm the fish. Dosing is based on the alkalinity (carbonate hardness) of the water. Copper toxicity increases as carbonates decrease, so a lower dose is required in low-alkalinity water. Charts can be found online. You'll need a copper test kit and alkalinity test kit to dose in the best manner. Otherwise, follow the directions on the treatment label.Avoid chelated or complexed copper medications. They are not effective..
