What is Seachem Purigen?


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 others by over 500%. Purigen controls ammonia, nitrites, and nitrates by removing nitrogenous organic waste that would release these harmful compounds. Purigen’s impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen progressively darkens as it exhausts and is easily renewed by treating bleach. Purigen is designed for both marine and freshwater use.

How Does Seachem Purigen Work? 


Selectivity: Purigen is the highest capacity organic filtration resin on the market. No other product can compare its ability to clear haziness and polish water to unparalleled clarity. Unlike other products on the market, simple ion-exchange resins, Purigen is specifically designed to be an organic scavenging resin. When metals and other contaminants fill ion-exchange resins, 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 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 macro reticular. 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. Purigen will change color from a pale blonde to a dark brown, almost black, as it adsorbs waste products. Once it is exhausted, it can be regenerated with a solution of bleach and water. The bleach will 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. However, 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 removed, which is the primary function of organic adsorption resins.
