I Have a brand new Hayward S210T sand filter (ZeoSand) paired with a 1HP 2-Speed Matrix Pump. Does the filter "filter" better on the low speed setting? I know that I will have to run the pump longer to get the required turn over but there is a significant head pressure difference at the sand filter gauge. Low = 2.5 PSI & High = 16.0 PSI. For the power savings alone I could run the pump on low 24/7 vs running the pump on high for 8-10 hours. Low speed consumes 210 watts and High speed consumes 1090 watts.
