I have a 36 watt uv that has been laying around and wondering if it would be worthwhile to put it in my ray pool? Its rated for 500 gallons so would it do anything on my 900 gallon set up or just sell the thing? I have read articles for both sides of the uv's which some say they are worthless and of course others say they work and how would i even know if it really works unless i am a scientist with microscopes and other gadgets.
