    Having trouble figuring out how long I should run my pump

    Hey guys. First time poster! Excited to try maintaining my pool the right way after fighting algae all summer last year. This is our second season with the pool (purchased home with existing install). As you can see in my signature, the pool is just over 16,000 gallons. Last year I ran the pump from morning to evening, but i think that was overkill. The pump manufacturer says it pumps ~83 gallons per minute, but I've read here that other conditions in the pool set up can affect that?

    Right now I have it on a timer where it runs 3 hours on, 3 hours off from 6 am to 9pm. Of course I want it to cycle the water sufficiently so that the chemicals are dispersed appropriately, but I'm not worried about having it run a little longer to keep bugs and stuff out of the water (living in Missouri, we have plenty). Do you guys have any advice?

    My TF-100 is arriving today so I can finally test my levels and start the process for opening the pool. All I've done so far is fill it up.

    Welcome!

    This will save me some typing: Pool School - Determine Pump Run Time

    Odds are, enough run time to clear the surface will also plenty to keep the water mixed and filtered.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Thanks for the reply, Richard. I did read that article before, and I think you've answered my question then. It's basically just providing enough circulation combined with how much aesthetic appeal you want
