I think this comment in itself is reason not to use one. It sounds like maybe you're not quite happy with things and you're looking for anothe rgadget to fix things. While UV can fight off bad things, it also kills good things, things that other things use for food sources. I would recommend trying to stay as natural as possible and finding a balance in your tank, rather than trying to tip the scales with too much technology.
Not saying UV is bad, but tons of tanks are beautiful with out it, and personally I try to strive for this without gadgets. JMO
