Using an all-natural zerolite mineral, Zeobrite provides superior water clarity compared to sand. Reduce backwashing by 50%, as well as the amount of chloramines in the water that cause eye irritation and chlorine odor. Zeobrite will filter particles as small as 3 microns; 10 times smaller than sand.
50 lbs. of Zeobrite is equivalent to 100 lbs. of sand. Lasts up to 5 years!
