Seachem Purigen is the highest capacity organic filtration resin on the market. No other product 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, Seachem Purigen is specifically designed to be an organic scavenging resin. When other ion-exchange resins are filled to capacity by metals and other contaminants, Seachem Purigen has barely begun to reach its potential. Seachem 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. Seachem Purigen removes that waste faster and more completely than anything else on the market.

Regeneration

Seachem Purigen can also be regenerated. As it adsorbs waste products, Seachem 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.
