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. Purigen is designed for both marine and freshwater use.

Isabella O. ★★★★★

I was skeptical about spending more on filtration media, but the macro-porous polymer structure really does grab dissolved organics that my sponges miss. Water clarity improved within two days and the little bag is still going strong after a month of heavy feeding.

Eli C. ★★★★★

My tank water has never stayed this clear between water changes, even with heavy feeding. The macro-porous polymer grabs dissolved gunk in a way that floss or carbon never did, and it's been holding up for weeks without needing a recharge.

Daniel ★★★★★

The way this polymer traps dissolved waste is wild—I can actually see the beads darken after a few days in my canister filter. My tank stays crystal clear even with heavy feeding, and it regenerates perfectly in bleach without losing effectiveness.
