This 25 lb bag of Diatomaceous Earth (DE) powder is a high-quality filtration media designed to deliver superior pool water clarity. Sourced from natural fossilized diatoms, DE powder provides one of the most efficient forms of mechanical pool filtration by trapping microscopic particles as small as 2–5 microns.

Ideal for use in DE-compatible pool filters, this powder creates a fine, porous layer on the filter grids that catches dirt, oils, pollen, algae, and even some bacteria—delivering crystal-clear results. It’s a natural, non-toxic option that outperforms sand and cartridge filters in terms of filtration precision.

Whether you’re doing a fresh charge or topping off after a backwash, this 25 lb bulk size is perfect for regular maintenance or large pools. DE powder is compatible with both residential and commercial pool systems.

• Removes particles as small as 2–5 microns
