Seachem Cuprisorb 100 ml Bagged is a highly effective, narrow-spectrum synthetic adsorbent filter material designed to safely remove copper and other heavy metals from both freshwater and marine aquarium systems. This powerful chelating resin specifically targets and extracts all forms of copper, including challenging chelated copper, ensuring a healthier aquatic environment for your inhabitants.

Unlike many competing products that are simple cation exchange resins, Cuprisorb utilizes a specialized chelating action that makes it uniquely effective in saltwater applications where other resins fail. It boasts a high capacity, with 500 mL capable of removing up to 15,000 mg (12 ppm) of copper from 1,200 L (300 gallons) of water. The media changes to a deep blue-black color when exhausted, providing a clear visual indicator, and can be easily regenerated for repeated use, offering long-term value.

This product is ideal for reef aquarium hobbyists and freshwater keepers looking to eliminate copper and heavy metal contamination, especially in tanks where copper-based medications were previously used. Its ability to gradually extract even precipitated copper over continuous service allows for the safe introduction of sensitive invertebrates and corals into systems that were once heavily treated. Cuprisorb is best placed in a high-flow area such as a canister filter or chemical filtration module to maximize its efficiency, making it an essential tool for maintaining pristine water quality.
