Just wondering about the positives and negitives if any of using a uv sterilizer on my tank. I have heard, (rumors) that a pod population will not survive if running a uv. Any truth to that? My main thing is that I hadf a problem with my tank about a month ago and was wanting to make sure it was gone, so i was thinking of adding a uv sterilizer to my system but just wanting to know any negatives about it first. I have a 125 gallon fowlr, with a 3" dsb, about 90 lbs of live rock, and a 30 gallon sump/fuge full of critters.
