Purigen is a unique, all-purpose filter media powerhouse that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%.
Designed for use in freshwater and saltwater tanks, Purigen is not a mixture of ion exchangers or adsorbents, but a one of a kind, macro-porous synthetic polymer with unheard of filtration capacity and minimal impact on trace elements.
Purigen controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. It significantly raises redox. It polishes water to unparalleled clarity. Purigen darkens progressively as it exhausts, and is easily renewed by treating with bleach. Why settle for anything less?
Rinse before use. Use in a fine mesh filter bag. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
Purifies and polishes up to 100 gallons of water for up to six months.
