Purigen® is a unique macro-porous synthetic polymer that removes both soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. It significantly controls ammonia, nitrites and nitrates by binding nitrogenous organic waste that would otherwise release these harmful compounds. Use of this product has very little impact on trace elements. It significantly raises redox as 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.
Available Sizes: 100 mL, 250 mL, 500 mL, 1 L, 2 L

Capacity: Purigen’s™ 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. It has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.
Regeneration: Purigen® can also be regenerated. As it adsorbs waste products, Purigen® will change color from a pale blonde to a dark brown, almost black. Once it is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally “burn off” the organics that have been removed from the tank. Watch out for products that claim to be regenerable with a brine solution. That is the regeneration procedure for ion-exchange purposes. A brine solution will not remove organics. While such resins have a limited capacity for organic adsorption, a brine regeneration process only replaces removed ionic compounds. It does not destroy large organic molecules that were removed, which is the primary function of organic adsorption resins.
Directions:Rinse before use. Use in a fine mesh filter bag. Each 1 L treats up to 4,000 L (1,000 gallons*) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
REGENERATION: 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 ChlorGuard™, Prime®, or equivalent dechlorinator per cup of water. Rinse well. Original color and full activity should now be restored and Purigen® is ready for reuse. Caution: some slime coat products may permanently foul Purigen® and render regeneration difficult. Do not reuse if odor of chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
Filtration Additives
Selectivity: Purigen® is the highest capacity organic filtration resin on the market. No other products can compare to its ability to clear haziness and polish 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. Purigen® generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. The primary source of nitrogenous compounds in an aquarium is waste. Fish, corals, even plants produce nitrogenous waste. Purigen® removes that waste faster and more completely than anything else on the market.

The Bag™ is an innovative welded filter bag with a durable non-stitched seam. It has a 180 micron mesh, is resistant to bleach, caustics, and acids, and comes with a convenient resealable locking closure. It is available in a convenient 5" x 10" size. It is ideal for all filtration products and has an exceptionally long life.
Unlike stitched seams, welded seams are not subject to degradation from exposure to bleach, caustics, acids, or other harsh environmental exposure likely to take place during regeneration of filter media. Caution should be excercised, however, to avoid overfilling or over-packing as welded seams can be forced to separate by excessive pulling forces.
