UV sterilizers ???
 

Does anyone use UV sterilizers, if so, your feed back would be appreciated.

I use a 30 Watt 36" unit on a 200G and have nothing bad to say about it. I also can't say that I notice any drastic improvement either.

I'm hoping that it reduces the chance of disease in my tank so it is a hard thing to measure.

I agree about the UV 's I have my sterilizer's flow set to the gph most effective to look after parasites, desease etc. I think they are a good addition to any fresh or SW tanks. I've had very good luck with Coralife Turbo-twist units.
