purfiltrum™ is a unique macro-porous synthetic polymer that removes soluble and insoluble organic impurities from water 5 to 10 times faster and more completely than all other competing products. It is the highest capacity organic filtration resin on the market outperforming even Seachem Purigen®, binding 10 to 15% more organic material. purfiltrum™ controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise be converted into these harmful chemicals. purfiltrum™ will not reduce the levels of trace elements, and it significantly raises redox. It polishes water to unparalleled clarity. purfiltrum™ progressively darkens as it removes impurities, and is easily renewed by treating with bleach per recommended regeneration instructions. purfiltrum™ is designed for both marine and freshwater use.
Sizes: 100 mL, 225 mL, 450 mL, 4 L
Rinse before use. Use in a fine mesh filter bag such as Seachem's The Bag™. Each 225 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: Once it is exhausted, it can be easily regenerated with a solution of bleach and water. Soak in a 1:1 bleach:water solution for 24 hours in a non-metallic container in a well-ventilated area, 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 3 tablespoons of alpha™, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak beads for 4 hours in a solution containing 2 tablespoons of buffer (Seachem Discus Buffer® or Neutral Regulator®) per cup of water. The original color and full activity should now be restored and purfiltrum™ is ready for reuse. Caution: some slime coat products may permanently foul purfiltrum™ and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. If uncertain, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
