Pros and Cons to UVfiltration in a Reef tank?

[Tom R]

The kill rate of a UV filter is a relationship to the wattage and the flow. The bigger the wattage the lower the flow the higher the kill rate.

I also believe that it kills the good with the bad. I use to use my UV for about a day once or twice a month.

As I am now on ZEOvit UV is not used (why spend all that cash to build a bacteria base and then kill it with UV).
