Mine is hooked up to my day cycle, and plumbed inline to the carbon reactor and zeolites both in phosban reactors...Hey when the suns out, so is the uv! Not recommended for the zeolites, but i figure the down time is sufficient enough. UV's keep bacterial populations around natural seawater, as their is a trend in aquariums to have higher than normal levels. among other things....
