So I've always used a UV
sterilizer in my aquariums, either freshwater or saltwater and I was convinced they did something to keep water quality up. Over a month ago I decided to try an experiment and see what would happen if I removed my UV
sterlizer from the saltwater tank. I have not seen any difference whatsoever in my water quality. Prior to this, even having the UV
sterilizer, I still had ich outbreak in the tank. However I used mine for the fact that I thought it was keeping algae in check.
I'm convinced that the refugium is the best thing I've ever done in keeping a saltwater tank, and my water has never been clearer and I've never had any major cyano
or nuisance algae issues. Years ago before fuges became commonplace I always had problems with this (one of the reasons I took a hiatus from saltwater fish).
When I had a large pond many years ago I used an enormous UV
sterlizer which *did* keep the algae in check. So there is a use for these depending on the situation.
