  • Seachem 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%. Seachem 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. Seachem Purigen darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen is designed for both marine and freshwater use.

    why Seachem Purigen is different:
    Selectivity: Seachem 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, Seachem 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. Seachem 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. Seachem 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.

    Seachem 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, can be used several times
    + for us in freshwater and marine water

    Application of Seachem Purigen:
    Rinse before use. Use in a fine mesh (180 micron or less) filter bag. Each 250 mL treats up to 1,000 L for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
