Depends on what you want to kill.

Aqua UV Classic with a Wiper would be my first choice. The wiper is important as the crystal sleeves tend to get coated and having the wiper eliminates the need for frequent dissasembly. That said, the flow you run through it will have a bit of a deciding factor on the wattage I would choose but I would go with a a minimum of 25 watts.

On my 120 system, with 30 gal sump, I'm guessing total system water volume is approx. 120 - I use a 18 watt UV. With both my skimmer and UV, I under size it as I don't want to make my system so sterile that the good stuff (i.e. bacteria, coral food,etc) aren't killed off. But that's just from my experience and my philosophy. I hope this helps
