Seachem Cuprisorb 250 ml

CupriSorb™ is a narrow spectrum, synthetic adsorbent based filter material for removing copper and heavy metals from either freshwater or marine water. 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. Size: 250 g Why It's Different Competing products are not chelating products, but merely cation exchange resins. Such resins can remove copper from freshwater but are ineffective in saltwater. 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 f
