Diatomaceous earth coats the fabric on the grids, and that coating is the filter medium. Once the fabric tears or the grid frame distorts, DE escapes into the pool and the filtration goes with it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatching the size\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDE filters are sized by square footage and the grid assembly has to match.
