Seachem Cuprisorb 250ml - Removes copper.

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 from water and, if in continuous use, from the gravel/substrate bed as well.

CupriSorb will allow maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates.

Competing products are not chelating products, but merely cation exchange resins.

Such resins can remove copper from freshwater but are ineffective in saltwater.

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 colour.

Rinse well, add sodium bicarbonate until foaming stops, and rinse again.

CupriSorb is now ready for reuse.

If original colour cannot be restored after several acid washes, proceed with rinses and bicarbonate step, then regenerate as HyperSorb or Purigen.
