CUPRISORB 250ml – Regenerable Chelating Resin for Copper Removal in Aquariums
CupriSorb 250ml by Seachem is a high-performance chelating resin designed to remove ionic and chelated copper and other heavy metals from freshwater and marine aquariums. Unlike traditional ion-exchange resins, CupriSorb acts with superior precision and speed, making it ideal for use in sensitive reef tanks or in emergencies involving copper contamination.
Each 250 ml can remove up to 7,500 mg (12 ppm) of copper in 600 liters of water. It also eliminates copper leached from substrates, supporting long-term detoxification. Once spent, CupriSorb changes to a deep blue-black, clearly signaling when regeneration is needed.
This resin is fully reusable through a simple regeneration process, offering a cost-effective and environmentally friendly solution for long-term aquarium health.
