Purigen Filter Media

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.

Features:

• 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

Purigen extremely effective and can provide visible reduction in haziness and water coloration from organics more quickly than almost any other product on the market. Purigen is specifically designed to be an organic scavenger. Purigen generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. As a result, Purigen will not target metals and other contaminants, which allows it to work for extended periods of time targeting organic waste products that can lead to yellowing and odors in your tank. Purigen removes that waste faster and more completely than anything else on the market.

Directions for Use:

• Rinse before use.
• Use in a fine mesh (180 micron or less) filter bag.
• Each 100 mL treats up to 100 US gallons for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
• For best results, Purigen should be placed so as to maximize the flow of water through it. It may be used in a media reactor, canister filter media chamber, box filter, or any high flow area of a trickle filter.

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.

• 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.
• Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of dechlorinator per cup of water.
• Rinse well.
• Original color and full activity should now be restored and Purigen is ready for reuse.

Note: Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach).

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.
