I've fallen off the UV bandwagon as well. I've run mine since the tank stopped cycling, and everything has been swell. However, as of late, some of my corals have not been expanding as much as I'd like, so I unplugged the UV about a week ago as an experiment, and everything definitely looks better. As I don't plan on adding any more fish, and my algae is under control, I don't foresee ever running the UV again.
