Purigen^®

•  Highest organic removal capacity
•  Possesses enhanced capacity owing to its vast surface area; both spherical and macroreticular
•  Helps control ammonia/nitrite/nitrate
•  Color changes as it exhausts; easily regenerated

Description

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. 

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.  

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 (180 micron or less) filter bag such as Seachem’s The Bag™.  Each 250 mL treats up to 1,000 L (250 US 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-metallic container in a well ventilated area and away  from children. Use regular 8.25% hypochlorite household bleach  (non-scented, no dyes, do not use a splash-less bleach). Rinse well,  then soak for 8 hours with a solution containing 4 tablespoons of Prime®,  or equivalent dechlorinator per cup of water. Rinse well. For  freshwater use, soak for 4 hours with a solution containing 2  tablespoons of buffer per cup of water (Discus Buffer®, Neutral Regulator®).  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  bleach/chlorine is detectable. In case of doubt, soak beads in small  quantity of water and test for residual chlorine with a chlorine test  kit.
