WATCH CRYSTALBRIGHT—Filter Media for Sand Replacement

Crystals greatly improve performance of sand filters without added work. Follow these step-by-step instructions to fill sand filters with WATCH CRYSTAL BRIGHT, Greater to refresh WATCH CRYSTALBRIGHT’s ammonium trapping capacity.

Greater Surface Area Traps Smaller Particles
WATCH CRYSTALBRIGHT is a high-purity natural zeolite. The surface area of WATCH CRYSTAL BRIGHT is 100 times greater than sand, thus allowing smaller particles to be trapped. WATCH CRYSTALBRIGHT's larger surface area greatly improves water clarity and increases the time between backwashes.

WATCH CRYSTALBRIGHT traps and holds ammonium ions (sand does neither). Less ammonia means fewer eye-burning chloramines and reduces the need for chemical shocks (lowering chemical expenses). The ammonium trapping qualities may require regeneration.

Under normal conditions, WATCH CRYSTALBRIGHT needs to be replaced about as often as sand. After filter use, WATCH CRYSTALBRIGHT may be added to your garden or potted plants as a soil conditioner or simply discarded as a non-hazardous waste.
