* Purigen is a premium synthetic adsorbent that is unlike most other filtration products.
Purigen is not a mixture of ion exchangers or adsorbents, rather a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen controls ammonia, nitrites and often hard to control nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds, with minimal impact on trace elements.
*SeaChem Purigen polishes water to unparalleled clarity and darkens progressively as it is exhausted
*Purigen removes many tannins and other organic water "yellowing" by-products that carbon cannot (this is especially helpful to use with new driftwood or to lower the "yellow" color of aquarium 2-3 days after introduction of Indian Almond Leaves or Peat)
*Purigen is easily renewed by treating with bleach and is designed for both marine and freshwater use.
*Purigen can be combined with Matrix or NPX Bioplastics Nitrate & Phosphate Reducing Polymer for even better results.
*However in planted freshwater aquariums, we primarily recommend SeaChem Matrix (as well NPX Bioplastics Nitrate & Phosphate Reducing Polymer is generally intended for Marine aquariums with a Protein Skimmer, although use with Purigen including a planted freshwater aquarium would be an exception).
*Since Purigen can affect Redox negatively as with similar products, use with caution in an aquarium with unbalanced Redox and use with products such as Regular AAP Wonder Shells is advised.
