Great response nater. I run my setup a little different. 18x36 vinyl with 2 speed pump. Filter run time is 11 hrs., on low speed I am probably moving about 35 gal/min. I believe on high its not economical or effecient for the SWC. Autopilot also, was well worth the investment.
By the way haven't tried Chem Geeks reccomendations. Have to read some more, I am also running a heater.
