CupriSorb is a powerful copper and heavy metal adsorbent. It quickly removes copper, making it ideal for emergency copper removal. CupriSorb eliminates all types of copper, including chelated copper, and remains effective until it turns dark blue. It can be regenerated multiple times. When used continuously, it will gradually remove copper, including precipitated copper from gravel or substrate. CupriSorb enables the maintenance of invertebrates in copper-treated aquariums by extracting and eliminating copper from substrates. 250 ml treats 600 liters.
