How long to run filtering?

[dwstewart]

Hi,

I have a 20000 gallon in ground pool with a 1.5 hp motor and sand filter. How long should I run the motor during every 24 hour period and is it best to run it at night or in the day?

Thanks,
Dave

It depends more on the flow of the pump than the horsepower.
