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.
