I cannot seem to clear up my agp which has a sand filter. This started late last year and continues now. Once things settle out, the pool water is fairly clear but this takes 3-4 days. When I vacuum the pool, it gets cloudier as I go along. It appears to me the sand filter is not filtering out some fine stuff. I saw a comment somewhere about using a cup or two of DE powder in the filter to get the really fine particles out.

Is this a doable thing? What will it do to the filter?

Any info would be appreciated,
