I run mine 24/7.
Justy make sure every six months you replace the UV light.

I do not run one as I hear the flow through it has to be really slow to be effective. Plus, I do not want beneficial bacteria killed by this in my tank.

Yes, it is true that it has to be a slow flow.
However, Coralife has made the TurboTwist and I absolutely love it. Water goes through the cylinder but it weaves its way through the cylinder thus giving it more exposure to the UV light.
Powerheads that are hooked up to a UV light should have lower gph to make the UV work for your tank.
I leave mine on 24/7 however there are some people I know that don't leave them on all the time.
