Advice please -re: value of UV steralizer

[wickedfrags]

I have spend disturbing amount of time and money in the saltwater hobby since the mid 90's and have owned 3 saltwater tanks over 200 gallons. I just set up a 90G reef tank with a bubble king skimmer and a Vertex Illumina.............a UV sterilizer was never even considered. Unless it is used on a quarantine system without a sand bed.......you will never see the diffference between using one and not using one. just my 2 cents.
