how long should a uv run in a reef setup? Being that I read it kills all bacteria good and bad, that possiblity couldnt be good to our eco systems. So I guess people who have had experience with using a uv in their reef system please give me some feedback as far as the duration this is left on. I have heard some people run them 24/7, some 8 hours per day. Thanks ***)
