I am setting up a UV Sterilizer and I am not sure of the best way to run it. It is a 3 tower 120 watt UV and it is going on a 300 Gallon Setup and I was told that it should be setup to run water through it really slow. Like put a relatively small pump with a ball valve in the line and let the water pass by the lights at a very slow rate. Does this make since to people?
