Seachem® Purigen® Aquarium Water Treatment

DescriptionSeachem 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 other competing products by over 500%.Features: Highest organic removal capacityPossesses enhanced capacity owing to its vast surface area; both spherical and macroreticularHelps control ammonia/nitrite/nitrateColor changes as it exhausts; easily regeneratedIntended For: Marine and freshwater aquariums Net Weight: Net 1 L (600 g/1.3 lb)Instructions: Rinse before use. Use in a fine mesh (180 micron or less) filter bag such as Seachemâs The Bag. Each 250 mL treats up to 1,000 L (250 US 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-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.
