CupriSorb™ is a powerful adsorbent of copper and heavy metals. It rapidly removes all types of copper, remaining effective until it turns a deep blue-black color. When in continuous use, it gradually pulls out precipitated copper and permits invertebrate culture in tanks previously treated with copper. A 100 mL bag is adequate for up to 60 gallons and removes over 3,000 mg of copper or 12 ppm in 60 gallons. It may be regenerated repeatedly. Marine or freshwater use.
DIRECTIONS: Use 250 mL (~1 cup) for every 150 gallons. For best results, CupriSorb™ 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. Exhaustion is indicated by a pronounced discoloration of the beads to a deep blue black color. When exhausted, CupriSorb™ may be discarded or regenerated.
REGENERATION: Soak in a non-metal container with 2 cups of water and 1-2 cup of muriatic acid (available with pool supplies: PAY HEED TO WARNINGS on acid container!). This is better done outside and away from children. Soak for 1 hour, rinse well. Repeat as required to restore the original color. Rinse well, add bicarbonate of soda until foaming stops, and rinse again. CupriSorb™ is now ready for reuse. If original color cannot be restored after several acid washes, proceed with rinses and bicarbonate, then regenerate as HyperSorb™ or Purigen™. Use MultiTest: Copper™ to monitor copper.
