I ran a small Lifegard UV sterilizer back when I first started reefing and my fish had ick. It actually didn't help and the fishes still had ick. I guess the wattage was too low for the 38G tank. But the other thing about it is that it kills phytoplankton and I'm not sure why I would want to kill the things that I actually purposefully buy and feed my tank (DT's).
Maybe a larger UV sterilizer might have saved my fish from Ick and Clownfish disease (not sure). I suppose it might be useful for fish only tanks and maybe not useful for coral only tanks?
