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.
So far Purigen has been keeping my tank crystal clear!
Great product to help with water conditioning.
Ability to recharge aspect is what makes it the perfect product
Excellent product for crystal clear water.
Received this as a gift. My 20 gallon was just dark and dirty all the time even with regular water changes. Popped in a bag of this and within 24 hours my tank was crystal clear. Planning to purchase more for all of my tanks.
My 36 gallon tank has the clearest water or has ever had. The nitrate levels are better and less water changes with one bag. I am buying another one for my 20 gallon tank and a back up.
