Product Details:
DIRECTIONS: Use one bag for each 400 L (100 US gallons). Rinse before use. Exhaustion is indicated by a pronounced discoloration of the beads from yellow to deep brown. For best results, Purigen should be placed so as to maximize the flow of water through it. It may be used in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter. 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. Rinse well, then soak for 8 hours with a solution containing 2 tablespoons of ChlorGuard, Prime, 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 Buffer, Neutral Regulator, or Acid Buffer). 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 the 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.
100 mL (Treats 400 L (105 US Gallons)).
