I installed a 25 watt Pentair UV Sterilizer. My return pump is a Cor15 from Neptune Systems. When I crank up the Cor15 to max flow, I can get only 335ish gph. Just wondering if I'm getting any benefit from the UVS or do I need to get a bigger RP? I think the flow for algae is over 700 gph?

According to the specs the Pentair Smart UV 25-watt is rated for 788 Gph (maximum). It suggests 472 Gph for algae & bacteria and 79-131 Gph for Protozoa bacteria. Depending on your tank size (this UV model is rated for up to 130 gallons) you should be ok for either algae or protozoa.
