Seachem CupriSorb™ is a narrow spectrum, synthetic adsorbent based filter material for removing copper and heavy metals from either freshwater or marine water. 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 service, it will gradually extract even precipitated copper and make invertebrate culture possible in tanks previously heavily treated with copper. CupriSorb™ is a powerful copper specific chelating resin.

Why it's different:

Competing products are not chelating products, but merely cation exchange resins. Such resins can remove copper from freshwater but are ineffective in saltwater.

Directions:

Use 500 mL for every 1,200 L (300 gallons*) to remove up to 15,000 mg (12 ppm) of copper. 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®.
