Seachem Purigen

Purigen® is a premier synthetic adsorbent designed for advanced water filtration in both marine and freshwater systems. It stands out due to its unique macro-porous synthetic polymer, which removes both soluble and insoluble impurities from water with exceptional efficiency—over 500% more effective than other products. Purigen® is particularly effective at controlling ammonia, nitrites, and nitrates by targeting nitrogenous organic waste, which can otherwise lead to the release of these harmful compounds.

One of Purigen®'s key advantages is its selectivity. Unlike standard ion-exchange resins, which become saturated with metals and other contaminants, Purigen® remains highly effective because it focuses on organic scavenging. Its capacity is enhanced by its vast surface area; Purigen® combines both spherical and macroreticular structures, providing a significantly larger surface area for adsorption compared to typical spherical beads.

Purigen® is also regenerable. As it adsorbs waste, it darkens from a pale blonde to a dark brown or black. This color change signals when regeneration is needed. The regeneration process involves treating Purigen® with a bleach solution, which effectively removes the accumulated organic matter, allowing the product to be reused.

Purigen® offers unmatched organic removal capacity, helps maintain low levels of ammonia, nitrite, and nitrate, and is easily regenerated, making it an invaluable tool for achieving pristine water clarity.
