Seachem Cuprisorb is a powerful adsorbent of heavy metals, and will remove copper and chelated copper more rapidly and efficiently than carbon, so it is excellent in emergencies. If placed in continuous use in the filter, it will gradually extract precipitated copper from the substrate bed, ensuring the prolonged safety of invertebrates. When exhausted it will turn a deep blue-black colour, and can be regenerated repeatedly.DirectionsUse 250 mL for every 600 L (150 gallons) to remove up to 7,500 mg (12 ppm) of copper. Use in a filter media 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 tests report zero copper. Use in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.
