Zeo, Inc ZeoSand-50 ZeoSand Swimming Pool Sand Replacement, Alternative Filter Media, 50 P, White, Pack of Four

Natural ZeoSand weighs twice as much as its sand volume but is twice as effective. The crystal structure, irregular shell and high surface make it a very effective trap for fine particles and ammonium ions compared to sand. Less ZeoSand is needed to fill a filter - 22.7 kg of ZeoSand replaces 45.4 kg of sand and makes a filter much more efficient. ZEOsand improves the performance of your sand filters by trapping more dirt and particles, reducing washing time. ZeoSand eliminates burning chloramines so you can enjoy superior water while saving energy and reducing the use of chemicals.
