    It takes three complete turnovers to remove 98% of the suspended solids. It's the Gage and Bidwell Law of Dilution.

    Don't think I'm smart or anything, I was just coincidently reading up on it yesterday.

    And I'll probably forget it tomorrow.

    While true, it still does not mean you need to do three turnovers. One turnover will hit about 70% of the water which is usually sufficient for proper sanitation and removing most of the solids. It is not necessary to remove all of them in one day since as you are filtering, more solids are being dropped so you will never have water without solids. That is the main reason for a chlorine residual.
