    Pump: Day or night?

    Didn't see this addressed in Pool School. Pump has been running 24/7 but finally the pool is clear and good. Would like to back off to 12/7. Would it be best to run at night or daytime? Pool is in full sun, sometimes a lot of wind. Hardly any debris though. Thanks! Steve

    as long as your pump can be run with people in it, I would run it during the day unless you can get better electric rates at night. you can see this article to determine how long to run it. I think 12 hours is overkill, but whatever works for you. pool-school/pump_run_time

    If you can, try to break it up, maybe 6 hrs during the day and 6 at night. This way doesn't let the water sit stagnent for so long and thus less chance of algae and FC "dead spots".
