Premium Sand Filter Media - 200 lbs for Pool, Pond & Aquarium Filtration - High-Quality Silica Sand for Water Treatment Systems

All natural ZeoSand weighs half as much as its volume in sand yet is twice as effective. The crystal structure, irregular shell, and high surface area make it a highly effective trap for fine particulates and ammonium ions compared to sand. It takes less ZeoSand to fill a filter - 50 pounds of ZeoSand replaces 100 pounds of sand and makes a far more effective filter media. ZeoSand improves your sand filters performance by trapping more dirt and particles decreasing back wash time. ZeoSand removes eye-burning chloramines so you can enjoy superior water quality while saving energy and reducing chemical usage.
