Does anyone have a suggestion r.e. a reasonable run time over a 24 hr. period for running my pool pump during the summer months down here in Tucson,Az. I'm currently running it for 8 hrs total...9pm to 1am, then from 5am to 9am. I'm trying to take a little of the heat stress off the motor. I'm running it at high speed(3100rpm) from 5 am to 9am and low speed(800rpm) at night from 9pm.to1am.
