What do you mean skimmer action? Also, what do you set the speed to during cooler temps and how much does the pump cost per a day to run?I set my SWG speed as my "Pool" speed. 1500 rpms. I set that for 23:55 hour runtime during the season. Then I set higher speeds when I want more skimmer action usually 3000 (another speed in the speed setup for the pump). I schedule that for 45 minutes every morning. When the 45 minutes is up, it simply reverts to the "Pool" speed.
