PURIGEN is a premium synthetic adsorbent that differs from any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique large-pore synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity exceeding all competing products by over 500%. PURIGEN controls ammonia, nitrite, and nitrate by removing nitrogenous organic waste that would otherwise release these harmful compounds.

Main Features:

• Highest capacity for organic removal
• Enhanced capacity due to its extensive surface area; large spherical and mesh structure
• Helps control ammonia/nitrite/nitrate
• Changes color when exhausted; easily regenerated

Instructions:
Rinse before use. Use in a fine mesh filter bag (180 microns or less) like the Seachem bag. For best results, PURIGEN should be placed to maximize water flow through it. It can be used in a canister filter, media chamber, box filter, or any high-flow area of a flow-through filter. Each 250 ml treats up to 1,000 liters (250 US gallons) for up to six months. Exhaustion is indicated by a change in color of the beads to dark brown or black.
