Seachem CupriSorb Filter Media - 250ml

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.
DIRECTIONS: Use 500 mL for every 1,200 L (300 gallons*) to remove up to 15,000 mg (12 ppm) of copper. 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.
