Some of you may have seen my failed attempt at a QT. Well that will likely be the downfall... I can't say for certain where it came from as it's only my original fish that are sick at this point. Catching them is a near impossibility. The added time and stress of doing so will likely make it worse. I've added my uv to the system but conventional knowledge says I'm too late. Came in this morning to find worms and ich. I know people have used prazipro in a reef tank... anyone with first hand experience?
