    Does Sand Filter Require Periodic Sand Replenishment?

    We're new pool owners, never having owned a pool before. My in-laws said that, when they used to have a sand filter (they have DE now) they would add sand to it a few times a year. Our pool builder didn't say anything about this, and I'm wondering if I should be adding sand to our Pentair Triton II sand filter once in a while? If so, how do I know when it needs sand, and how do I know how much to add?

    (Apologize in advance if this is a dumb question!).

    You shouldn't have to. If you do need to, it would indicate a problem with the filter or an oversized pump causing sand to be washed out.

    Thanks John...I'm relieved to know this, as I want to make sure we're doing everything "right".
