No. I ran UV's a loooong time ago, didn't think they helped very much, so I don't use them now. I believe I have tried about every ich cure out there at one time or another, and have found that only copper works. However, with corals, can't use it. So I am left with natural immunity and antibodies as the only cure....and food with garlic, which seemed to help cure my Powder Blue.Aquascaper said:are you running a uv on that tank Ken?
