Seachem Purigen

Purigen® is a premium synthetic adsorbent 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 further exceeds by 500% all other competing products.

Purigen® controls ammonia, nitrites and nitrates by removing nitrogenous organic wastes that would otherwise release these harmful compounds. Purigen's impact on trace minerals is minimal. It considerably increases the redox. It polishes the water to unparalleled clarity. Purigen® darkens as it runs out and is easily replenished by treating with bleach. Purigen® is designed for marine and freshwater use.
