PoolFix Diatomaceous Earth Pool Filter Powder – Professional-Grade DE Filtration Media (6 lb, 12 lb & 24 lb)

PoolFix Diatomaceous Earth is professional-grade filtration media trusted by pool service technicians and homeowners alike. Made from flux-calcined fossilized diatom exoskeletons, PoolFix DE coats your filter grids with millions of microscopic porous particles that trap contaminants down to 3–5 microns in size — delivering a level of water clarity that sand and cartridge filters simply can't match. Whether you're maintaining a residential backyard pool or a high-demand commercial installation, PoolFix DE is the industry-standard choice for keeping water polished and crystal clear all season long.

• ✔ Filters down to 3–5 microns — removes algae, bacteria, debris, and fine particulates that sand and cartridge filters miss, leaving water polished and crystal clear
• ✔ Flux-calcined, high-permeability grade — optimized for pool filtration with superior flow-through rates and even grid coating without clumping or bridging
• ✔ Compatible with all major DE filter systems — works with Hayward, Pentair, Jandy, and all other standard above-ground and in-ground DE filter units
• ✔ Flexible sizing — 6 lb bags — available in 6 lb, 12 lb (2-pack), and 24 lb (4-pack) configurations, making it easy to stock exactly what you need for any job
• ✔ All-natural, non-toxic media — derived from naturally occurring diatom deposits; wear a dust mask when handling per standard safety practices
• ✔ Simple application — mix with water and pour through the skimmer with the pump running; no special equipment or additives required

Use 1 lb per 5 sq. ft. of filter area on initial startup or after a full grid cleaning; use 1 lb per 10 sq. ft. after each backwash cycle. PoolFix DE is compatible with all Hayward Pro-Grid, Perflex, Pentair Quad DE, Jandy DEV Series, and virtually all other residential and commercial DE filter systems. Recharge with PoolFix DE after every backwash to keep your filter performing at peak efficiency.
