Zeolite

Rapidly eliminate toxic ammonia spikes and protect your fish during water quality emergencies with our range of natural zeolite filter media and ammonia-absorbing volcanic rock. Sourced from high-purity natural clinoptilolite deposits, zeolite provides an instant chemical absorption safeguard for established koi ponds, newly maturing filter systems, and quarantine facilities.

Featuring a microscopic, honeycomb crystalline lattice, zeolite works through rapid ion exchange, binding harmful ammonium ions from the water column before they can convert into toxic free ammonia. This provides immediate relief to fish during heavy feeding periods, seasonal bio-load surges, or unexpected filter disruptions while your nitrifying biological colonies recover. Highly versatile and completely chemical-free, zeolite can be placed in mesh media bags within multi-bay filters, skimmer baskets, or waterfall headers where water flow is highest. When the media becomes saturated, it can be easily recharged and reused multiple times by soaking it in a concentrated pond salt solution to release the captured ammonia. Explore our complete zeolite collection to supply your pond with dependable, fast-acting mineral media engineered for emergency water safety and pristine aquatic balance.
