Yes, this issue sounds familiar, Mark.
There ARE tanks in his book that don't use UV, but there are MANY that do. Is it needed? No. Is it an asset? I think so. I do agree that it's not as common on reef tanks because of theories which I, and apparently others, think are bunk (UV kills pods, coraline, etc). I, and others, run UV 24/7 and my pods/coraline spread like crazy. You can't argue with success. I said it before, and I'll say it again:
I have yet to see a thread/post by someone that has added a UV onto their reef and saw negative effects afterward.
