The grids are a frame, and the diatomaceous earth coating laid over them is what traps debris. That coating filters down to a finer particle than sand or a cartridge can manage, which is why DE pools tend to look sharper than the rest.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRecharging\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe coating leaves with the backwash water. After every backwash, the DE has to be replaced by mixing the measured amount with water and pouring it slowly into the skimmer while the pump runs. Skip it and the filter runs with bare grids, passing debris and wearing the fabric out early.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGetting the amount right\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe amount your filter takes is set by its size, so go by the figure on the filter label or in the manual.
