SeaChem Purigen

What is SeaChem Purigen?

First, I will say what Purgien is not; Purigen is NOT a treatment or water conditioner, rather Purigen is a chemical Filtration Product or "Filter Media".
Purigen is a premium synthetic adsorbent that is unlike most other similar filtration products such as Bio-Chem Zorb or Boyds Chemi-Pure.
Purigen is not a mixture of carbons, ion exchangers or adsorbents, rather Purigen is 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%. Sea Chem 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.

Purigen possesses enhanced capacity owing to its vast surface area. All other resins on the market are purely spherical extruded beads. These beads remain smooth even under a microscope. Purigen is both spherical and macroreticular. A macroreticular resin is made of two continuous phases, a continuous pore phase and a continuous gel polymeric phase. The polymeric phase is structurally composed of small spherical microgel particles agglomerated together to form clusters, which, in turn, are fastened together at the interfaces and form interconnecting pores. The surface area arises from the exposed surface of the microgel glued together into clusters.
The result is microscopic pores that increase its usable surface area to many times that of a purely spherical resin.

The result is that Purigen is the highest capacity organic filtration resin on the market. No other products can compare to its ability to clear and polish yellow or cloudy water to unparalleled clarity. Unlike other products on the market which are simple ion-exchange resins, Purigen is specifically designed to be an organic scavenging resin. When ion-exchange resins are filled to capacity by metals and other contaminants, Purigen® has barely begun to reach its potential.

ATTRIBUTES OF PURIGEN

*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 ordinary carbon or carbon based products 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 has no known effect on bacteria. It takes all the dye of e.g. peat, etc. allowing for more light available for plants.

*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).

*Sea Chem Purigen is easily renewed by treating with bleach and is designed for both marine and freshwater use.

Directions; Soak in a 1:1 bleach:water solution for 24 hours in a non-metalic container in a well ventilated area and away from children. Rinse well, then soak for 8 hours with a solution containing 2 tablespoons of Prime, or equivalent dechlorinator (Water Conditioner) per cup of water (do not use slime coat dechlorinators such as Stress Coat or Novaqua).
Then, rinse well. After this, original color and full activity should now be restored and Purigen is ready for reuse.

TIP: I suggest using De-ionized/distilled water for both the soak and rinse for best results (more important for the soak)
