About this item

Product details

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.

Purigen

This bag is great for removing organic waste from the water and polish's the water as well. I feel it is the best product on the market for what I described above.

Works fast

This stuff works great !! Be careful opening the bag as the little bag inside was caught in the seam of the outer bag which caused the inside bag to tear. Nothing a little tape couldn't fix but could have been a big mess.
