Celatom

Celatom is the diatomaceous earth (DE) filter media that has kept pools sparkling for more than 50 years. A flagship brand of EP Minerals — a U.S. Silica company based in Reno, Nevada — Celatom DE is billed as the number-one DE filter media in the world for swimming pools. It's a completely natural product, made from the fossilized remains of microscopic freshwater diatoms, and it filters out particles down to 2 microns — a level of clarity sand and cartridge media simply can't match. That ultra-fine filtration also captures many of the particles associated with recreational water illness and can reduce how much chlorine and shock your pool needs. NSF certified for swimming pool use, Celatom is the easy choice for DE filter owners who want crystal-clear, polished water with a proven, all-natural filter aid.
