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 synthetic that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others. Purigen controls ammonia, nitrites, and nitrates by removing waste that would otherwise release these harmful compounds. Purigen's impact on trace elements is minimal. It significantly raises redox and polishes water to unparalleled clarity. Like HyperSorb, Purigen darkens progressively as it exhausts, and is easily renewed by treating with household bleach. Purigen is designed for both marine and freshwater use.
A 100 mL bag of Purigen purifies and polishes up to 100 gallons of water for up to six months.

Directions: Rinse before use. Use in a fine mesh filter bag. Each 1 L treats up to 4,000 L (1,000 gallons*) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
Regeneration: Soak in a 1:1 bleach:water solution for 24 hours in a non-metalic container in a well ventilated area and away from children. Rinse well, then soak for 8 hours with a solution containing 2 tablespoons of ChlorGuard, Prime, or equivalent dechlorinator per cup of water. Rinse well. Original color and full activity should now be restored and Purigen is ready for reuse. Caution: some slime coat products may permanently foul Purigen® and render regeneration difficult. Do not reuse if odor of chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
I have been using Seachem's Purigen for over a year and it works I just checked my ammonia, nitrate and nitrite levels and all are at 0ppms. Although very easy to recharge this stuff with bleach I just replace with new. Thanks Seachem for making my tank chores easier!!!
