Purigen is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macroporous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all other products by over 500%. Purigen controls ammonia, nitrites, and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen's impact on trace elements is minimal. It significantly increases redox. It polishes water to unparalleled clarity. Purigen gradually darkens as it exhausts, and is easily regenerated by treating it with bleach. Purigen is designed for both marine and freshwater use.
