    Hayward SP15922S--how long to run on low?

    I have a Hayward SP15922S Power-Flo Matrix Above-Ground Pump 2-Speed and I run it on low for my 21 fr pool.
    My water is pretty darn clear as I keep up with the maintenance. am I running my pump TOO long ? I believe my pool is about 10,400 gallons. I am not sure how much HP my pump puts out. I have read multipe websites where some say its a 1hp pump and other say its a 1.5 HP. I have no idea what HP it pumps out on low. Can anyone assist ?

    All you have to do is run the pump long enough to keep the water looking as clear as you desire. IF it is clear now and you want to save some money, shorten the run time and see how the water looks.


    Generally low speed has half the flow rate of high speed and uses 1/4 the amount of electricity over a given amount of time.
