Seachem Purigen — East Ocean Aquatic
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 macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others 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.
