    Enough to get a complete turn over of pool water. Knowing your size/kind of pump would give you an idea of about how many gpm it pumps. Then just add a some time to make sure.

    That's your filter info, your pump info would be listed on your pump...

    Your pool volume calculates to 13500 gallons. If you are moving 35gpm in 8hrs it would be 16800 gallons.

    Take a look at How To Determine Pump Runtime in Pool School. You can start with something around 6 to 8 hours as a guess of your turnover time, and then adjust things based on how the water looks.
