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 exceeds all other competing products by more than 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 gives water a bright glow for unparalleled clarity. Purigen® progressively darkens as it is depleted and is easily renewed by bleach treatment. Purigen® is designed for both marine and freshwater use.
