Seachem Purigen, 1L, Silver

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. KEY 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 DIRECTIONS: Rinse before use. Use in a fine mesh (180 micron or less) filter bag such as Seachem's The Bag. For best results, Purigen should be placed so as to maximize the flow of water through it. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Each 250mL treats up to 1,000L (250 US gallons) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
