CupriSorb is a powerful adsorbent of copper and heavy metals. CupriSorb will remove copper more rapidly and efficiently than carbon and is thus ideal for emergency copper removal. It extracts all types of copper, including chelated copper, and remains effective until it turns a deep blue-black color. It may be regenerated repeatedly. If placed in continuous use, it will gradually extract even precipitated copper from the gravel/substrate bed as well. CupriSorb will allow maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates.

• Use Instructions: Use 250 mL for every 600 L (150 US gallons) to remove up to 7,500 mg (12 ppm) of copper. Use in filter media bag such as The Bag™. For best results, CupriSorb™ should be placed so as to maximize the flow of water through it. To remove undetectable substrate leaching copper keep CupriSorb™ in use for at least 2 weeks after copper tests report no copper. Use 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. Use MultiTest™ Copper to monitor copper. 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 best done outside and away from children. Soak for 1 hour, rinse well. Repeat as required to restore the original color. Rinse well, add sodium bicarbonate 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 step, then regenerate as HyperSorb™ or Purigen®.
