APC 36 sq ft DE Filter Grid Complete Set (8-Pack) - APCFS2003

The APC DE Grid Complete Set APCFS2003 is a premium full replacement set of D.E. (Diatomaceous Earth) filter grids engineered to restore peak filtration performance in your pool. Standing 18" tall and covering 36 square feet of filtration area, this 8-piece set captures microscopic particles, dirt, and debris down to 2–5 microns — delivering crystal-clear water all season long. Built with heavy-duty, chemically resistant materials and sonically welded stitching, the APCFS2003 is a direct drop-in replacement for Hayward, Pentair, Pac-Fab, and other popular 36 sq ft D.E. filter systems.

🚩 PRO TIP

When replacing your D.E. grids, always backwash the filter first to remove spent D.E. media, then inspect the manifold and standpipe for cracks before installing the new grid set. After installation, re-charge the filter with fresh D.E. powder at the rate of 1 lb per 10 sq ft of filter area (approximately 3.6 lbs for a 36 sq ft filter) for optimal filtration efficiency.
