It extracts all types of copper, including chelated copper, and remains effective until it turns a deep blue-black color. It may be regenerated repeatedly. If placed in continuous service, it will gradually extract even precipitated copper and make invertebrate culture possible in tanks previously heavily treated with copper. CupriSorb is a powerful copper specific chelating resin.
