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 others by over 500. Purigen controls ammonia nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen???s impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen darkens progressively as it exhausts and is easily renewed by treating with bleach. Purigen is designed for both marine and freshwater use. This product is sold by volume. Cited weight is minimal weight.

DIRECTIONS Rinse before use. Use in a fine mesh filter bag. Each 1 L treats up to 4000???L (1000 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 11 bleachwater 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. For freshwater use soak for 4 hours with a solution containing 1 tablespoon of buffer per cup of water (Discus Buffer Neutral Regulator or Acid Buffer). 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
