SeaChem Purigen
PurigenTM 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%. PurigenTM controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen'sTM impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. PurigenTM darkens progressively as it exhausts, and is easily renewed by treating with bleach. PurigenTM 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 4,000 Litres 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 and 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 ChlorGuardTM, PrimeTM, 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 BufferTM, Neutral RegulatorTM, or Acid BufferTM). Original colour and full activity should now be restored and PurigenTM is ready for reuse. Caution: some slime coat products may permanently foul PurigenTM and render regeneration difficult. Do not reuse if odour 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.
