I use a UV filter for a saltwater aquarium, and as long as time has gone on, there has been the debate between the ozone users and the uv users, I went with UV as it fit my aquarium setup quite nicely, vs. the ozone which would have required a new protein skimmer, and I didn't want that hanging off the back of my tank (the entire filtration system is built into the back of the tank, all acrylic, totally custom setup (at the time)) and the skimmer that is incorporated doesn't accommodate ozone well.

Either one will sanitize your water. The UV filters are cheap and easy and safe.
