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.


  • Use 250 mL for every 600 L 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.
