Four of this size are required, out of the 6 grids the filter holds in total.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the grid does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA DE filter does not filter through the grid itself. The grid is a frame with a fabric skin, and the diatomaceous earth you add coats that fabric. The coating is the filter medium. The grid just has to hold it evenly and stay intact under flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA tear or a seam split lets DE pass straight through, which comes back as powder in the pool and a return that never quite clears after a recharge. Check each grid against the light with the manifold out.
