    determining how long to run pump

    I am wondering how to figure out how long it takes a pump to turn the water over completely? Need to figure out how long to run my pump atleat all my water makes it once thru the filter a day.

    Thanks

    With your pool size and pump, a turnover is the range of 1.5-2 hours.

    A Hayward 1 HP above ground pump should be moving around 60 to 80 GPM. Assuming 60 GPM and 5300 gallons gives around 1.5 hours.

    The Pentair web site is designed for in ground pools.

    The Pentair site has a minimum pool volume of 10k but with that gives a turnover of 2.6 hours so I'm not sure how you got 5.3 hours. 53% (5300/10000) of that value is 1.4 hours but an inground pump will probably pump more water. I used the mid point on a typical above ground Hayward pump which was 60 GPM. Either way the number is close to 1.5 hours.
