Is there a particular reason you think you need one? IMHO, there's only a very few specific instances to use a UV, and it's not something you want running constantly.

Thanks Mike, I couldn't remember that name. That's the one I have as well, I've only ever used it once in my FW system for a very specific purpose, never needed it in my reef. They're a bit pricey for an item not needed often.
