Hayward Progrid diatomaceous earth filter

The Hayward Pro-Grid offers a filtering capacity of incomparable quality (1 to 3 microns, sand filters range between 40 to 50 microns) with a large capacity of pool cleansing whatever the dimensions of your pool. This filters tank is injected with Permaglass XL (reinforced with glass-fiber) offering the best in quality and long lifespan. The Pro-Grid is the result of high-technology that is user-friendly for everyday use (sealed, one piece tightening collar).

How does a diatomaceous earth filter work:
The filter is constituted of a tank in which the filtering module is placed. This module is composed of several filtering elements named "frames". The frames are made from a resin. A synthetic fabric is stretched over the frame. These frames maximise the filtration area and offer longer intervals between cleaning.
The diatomaceous powder will be placed on the fabric of the "frames" and will constitute the filtering medium.
Diatomites are fossilised skeletal remains of microscopic aquatic plants called diatoms, covered in porous, silica envelopes.
A group of these vegetal "skeletons" form a fine white powder, comparable to plaster. This is the substance used for filtration.
During backwash, the residue of the Diatomites will be ejected, indicating a recharge is required from time to time.
Warning : Because Diatomites are prone to clogging, the residue of these filters should not be evacuated towards a soak-pit.

Water quality is a main concern for all pool owners. The Pro-Grid is a sure choice.
