I run my pump 6:00 AM to 10:00AM and then again from 1:00 PM to 6:00PM and I have a 24,000 gallon pool. I like to run the pump during the hotest times of the day so that the heat from the solor blanket distributes throughout the pool. If I run it overnight and the outside temperature goes down to 65 or so, the pool water cools down also.
