How strong should the pump be going into the UV sterilizer? Someone told me it was 110. right now i have a rio 600 pumping into the UV, this is 200gph . should i switch it to a rio 200 which is only 138gph? or even smaller?
a slower pump would be prefferencial. the longer the water is exposed to the bulb the more it kills. i have a 36w uv and have a mj1200 hooked up to it.
