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.

Features:

• 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: 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.
