Purigen – 34 oz. – 1 L

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 synthetic that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others. Purigen controls ammonia, nitrites, and nitrates by removing waste that would otherwise release these harmful compounds. Purigen’s impact on trace elements is minimal. It significantly raises redox and polishes water to unparalleled clarity. Like HyperSorb, Purigen darkens progressively as it exhausts, and is easily renewed by treating with household bleach. Purigen is designed for both marine and freshwater use.

A 100 mL bag of Purigen purifies and polishes up to 100 gallons of water for up to six months.

Proprietary synthetic macroporous polymer resin.
