Product description CupriSorb aquarium water treatment 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 from your fish tank water. It extracts all types of copper from water and, in continuous use, from the aquarium gravel/substrate bed as well. CupriSorb will allow maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates. Directions Rinse the CupriSorb before using it for the first time, then place it in your aquarium or pond filter according to the manufacturer's instructions.
