i have a UV, i dont use it at all, my fish had never caught any diseases or parasites. also to save some electricity.

So if you add a UV make sure you are able to add different suppliments into the water to ensure that good bacteria is still in the tank. None the less its a great addition to any FOWLR set up. I will be using one on my 330 as soon as its set up for my sharks.
