THE SUPERIOR ALTERNATIVE TO SAND - FOR BETTER FILTRATION & WATER QUALITY! Start using ZeoSand™ instead of sand in your sand filter. Using 100% natural zeolite minerals, ZeoSand™ provides excellent water clarity, purity, and quality. ZeoSand™ has nearly 9800 times more square footage than sand, enabling it to filter small particles down to 3 microns for exceptional water clarity - that's 10 times smaller than sand! This amazing filtering media also removes the ammonia produced from dead organic material in the water, reducing eye irritation and odor. Plus, it cuts down on chemical demand - saving you money on chemicals! ZeoSand™ is easier to use than sand. You will only need one pound of ZeoSand™ for every two pounds of sand your filter requires - 1/2 the effort! Since ZeoSand™ has a greater capacity for particulates than sand, backwashing will be much less frequent. Comes in a 25 lb. bag. How can you go wrong? Turn your sand filter into a super filter with ZeoSand™!
