Seachem Purigen

Purigen is a high-quality synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a single macroporous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by more than 500%. Purigen controls ammonia, nitrites and nitrates by removing organic nitrogen waste that could release these harmful compounds. The impact of purigen on trace elements is minimal. It significantly increases redox. It polishes water for unparalleled clarity. Purigen darkens gradually as it escapes, and finds itself easily by treating it with bleach. Purigen is designed for use in sea and fresh water.
