There's really no need for a UGF system in any tank, though there are those among us who insist that a reverse flow UGF is a great investment because it gives a huge surface area for bacteria, requires no media, and requires only periodic maintenance.
Personally I think it's too much worry for someone like me, but if it's something that interests you then look into it. Again, it's really not a necessary or seriously beneficial thing. But....
Several people on aquariacentral.com (I know daveedka is one of them) swear by RFUGFs and they might be able to help you with it.
