The porous nature and large amount of surface area of Zeolite offers additional benefits besides great filtration. More surface area, trapping more dirt in the Zeolite itself, means there is better water flow thru the filter. Zeo traps particles as small as a DE filter without the need to add DE powder, a known carcinogen that is expelled into the yard when a backwash is done and turns to loose white dust once dry. An important and additional benefit is the reduction of chloramines. Chloramines come from the combination of the chlorine disinfectant (chlorine produced by a salt system, or chlorine tabs, or chlorine shock) and the perspiration, body oils and urine from swimmers. Chloramines then off gas into the air just above the water. Zeo traps ammonia molecules that reduces the chloramine gas.
The Zeolite's high dirt loading ability also means fewer backwashes, saving you money on water costs throughout the year. Zeolite is a great product and one I highly recommend for your next sand change.
