Minimum time to filter pool daily?

[windfix]

The rule of thumb that we've always advised is to run the pump long enough to completely turn your water over at least once daily (during the swim season, anyway.....it can be substantially cut down if you leave your pool open during the winter).

Thanks, I am going to try dropping from 7 hours to 4 and see what happens. At 96 gpm on the filter, it should take just under 4 hours to filter the whole pool.
