Purigen is a synthetic absorbent 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 taking out nitrogenous organic waste that would have been released to the tank. Purigen’s impact on trace elements is negligible. It considerably raises redox. It polishes water to unmatched clarity. Purigen darkens over time as it exhausts, and is easily reused by treating with bleach.
Rinse before use. Use in a fine mesh (180 micron or less) filter bag such as Seachem’s The Bag™. 100ml size is pre-bagged.
Each 250 mL treats up to 1,000 L 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-metallic container in a well ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach). Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime®, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 2 tablespoons of buffer per cup of water (Discus Buffer®, Neutral Regulator®). 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 bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
Purigen is designed for both marine and freshwater use.
