Seachem Purigen - Filter Media / Absorber / Adsorber. 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. Purigens impact on trace elements is minimal. 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. 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 : Purigens 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.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. Use in a fine mesh (180 micron or less) filter bag such as Seachems 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.
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.
