Seachem Purigen Organic Filtration Resin - Fresh and Saltwater 500 ml (116016308)

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 other competing products 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.

It significantly raises redox.

It polishes water to unparalleled clarity.

Purigen darkens progressively as it exhausts, and is easily renewed by treating with bleach.
