SAND

Sand has a basically flat surface. Consequently, sand filters by trapping particulates between the grains of sand. The grains of filter sand in your filter create many small voids between the grains that allow the water and smaller particulates to flow down through your filter to be pumped back into your pool.

A grain of ZEOBEST has thousands of times more surface area than a similar sized grain of sand. 

ZEOBEST

ZEOBEST is a filtration grade clinoptilolite zeolite. All varieties of zeolite were created from volcanic ash that thousands of years ago were deposited in salt water beds. Mother Nature, over these many years, created zeolite. They are a member of the aluminum silicate mineral family.

ZEOBEST is anything but a flat surface. A grain of ZEOBEST has many nooks and crannies….something more along what we think the moon’s surface looks like with its many deep craters and high mountains. 

ZEOBEST provides dual filtration. As you can see in our animation, ZEOBEST filters similar to sand by trapping the larger particulates between the grains of ZEOBEST. 

Secondly and this is how ZEOBEST provides DE-like filtration down to 3 microns, ZEOBEST filters the smaller particulates by catching them within the nooks and crannies of the grain of ZEOBEST itself. 

A ZEOBEST filter bed will provide filtration deeper into the filter bed due to its tremendous surface area and holding capacity. Smaller particulates may escape down through the voids between the grains of ZEOBEST but they will eventually be captured somewhere in your ZEOBEST filter bed.

Another significant benefit of ZEOBEST is less frequent backwashes. Most ZEOBEST customers say that if they backwashed once a week with sand that they are now backwashing once every two weeks with ZEOBEST.
