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, even HyperSorb, by over 500%.
Purigen removes proteins, nitrites and nitrates, ammonia, and a broad spectrum of organics, yet its impact on trace elements is minimal. It significantly raises redox.
It polishes water to unparalleled clarity. Like HyperSorb, Purigen darkens progressively as it exhausts, and is easily renewed by treating with household bleach.
A 100 mL bag of Purigen purifies and polishes up to 100 gallons of water for up to six months.
Marine or freshwater use.

Cadillac of Clean Review by Mark
Quality Price Value
I purchased this product to remove tannins from my tank. I was one water change and some tea coloured water away from tossing out my beautiful piece of mopani. purigen saved my bacon. I have never in all my experience in aquatics come across something that works so well! 100% worth every penny. It does seem like a hefty price to pay howevery it is amazing at what it does and you can recharge it! (Posted on 3/23/2017)
