U.S. Silica Mystic White II Pool Filter Sand | 50 lb. Bag | SAND50

The premium, high-performance filtration media designed to keep your pool water brilliantly clear and completely free of microscopic debris. U.S. Silica's Mystic White II Pool Filter Sand is widely considered the gold standard for residential and commercial sand filters. By upgrading your filter vessel with this specialized, high-grade silica, you instantly enhance your system's ability to trap fine dirt, body oils, algae, and pollen, ensuring your backyard oasis remains perfectly pristine.

Unlike standard, cheap river sand that features smooth, rounded grains, Mystic White II is distinctly angular. This sharp, jagged structure allows the sand grains to lock together loosely in the filter bed, creating millions of microscopic, jagged pathways that actively snag and hold onto debris as water passes through. It provides exceptional water clarity while preventing the dreaded "channeling" effect that ruins the efficiency of lesser filter sands.

Features

Angular Grain Structure: The secret to its superior filtration. The highly angular, jagged shape of the silica grains provides exponentially more surface area to catch and trap microscopic debris compared to standard, smooth-edged sand, resulting in noticeably clearer water.

Precision Graded #20 Silica: Carefully screened and graded to meet exact pool industry specifications (Standard #20 pool grade). This precise sizing ensures optimal water flow through your filter tank, preventing the sand bed from packing too tightly and overworking your pool pump.

100% Natural & Chemically Inert: Composed of incredibly pure, natural silica. It will absolutely not dissolve, break down, or react with any harsh pool chemicals like chlorine, bromine, shock, or acid. It adds zero total dissolved solids (TDS) or unwanted minerals to your pool water.

Prevents Channeling: Because the angular grains interlock perfectly, this sand resists the tendency to clump or form deep channels. This ensures that water is forced evenly through the entire sand bed rather than cutting a straight, unfiltered path to the bottom of the tank.

Long-Lasting Performance: A single application of Mystic White II typically lasts 3 to 5 years in a standard residential pool before the jagged edges naturally begin to wear smooth. This provides years of reliable, low-maintenance filtration.
