Seachem 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 colour. It may be regenerated repeatedly. If placed in continuous use, it will gradually extract even precipitated copper from the gravel/substrate bed as well. Seachem CupriSorb allows maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates. CupriSorb is a powerful copper specific chelating resin. 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 250ml for every 600L to remove up to 7,500mg (12 ppm) of copper. Use in a filter media bag such as The Bag from Seachem. For best results, Seachem CupriSorb should be placed so as to maximise 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 colour. Use Seachem MultiTest Copper to monitor copper levels. 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. 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.
