I didn't realize, Greg, that you were running UV in your tanks. I have no idea if there is any scientific or anecdotal backing for this, but does UV kill any bacteria or other micro organisms in your tank that are beneficial to your tank ecosystem and corals?

And I do remember you saying a while back that you thought your system was "too clean" and your corals may not be getting enough nutrients. Could the UV system have anything to do with that?
