SeaChem Purigen Organic Filtration 500 Milliliter

Purigenª 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%. Purigenª controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen'sª impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigenª darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigenª 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 500 mL treats up to 2,000 L (500 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 ChlorGuardª, Primeª, 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 Bufferª, Neutral Regulatorª, or Acid Bufferª). Original color and full activity should now be restored and Purigenª is ready for reuse. Caution: some slime coat products may permanently foul Purigenª 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. Royal Item Number: ASM163
