Seachem CupriSorb 500 ml is a powerful, narrow-spectrum synthetic filter media specifically designed for the rapid and efficient removal of copper and heavy metals from both freshwater and marine aquariums. As a copper-specific chelating resin, it excels in extracting all types of copper, including challenging chelated forms, making it far more effective than generic cation exchange resins, especially in saltwater environments where other products may fail. It is an ideal solution for emergency copper removal and maintaining pristine water quality.

A key feature of CupriSorb is its visual exhaustion indicator; the media changes color to a deep blue-black as it adsorbs copper, clearly signaling when it's time for replacement or regeneration. This versatile media can be regenerated repeatedly, offering long-term value. When placed in continuous service, it demonstrates the remarkable ability to gradually extract even precipitated copper that has leached into the gravel or substrate bed, ensuring thorough decontamination of the aquarium system.

This product is best for aquarists who need to quickly and reliably eliminate copper from their tanks, whether after medication treatments or to prepare a system for sensitive invertebrates that cannot tolerate copper. It is also invaluable for long-term use to prevent copper accumulation and remove undetectable, leaching copper from substrates, thereby creating a safer and healthier environment for all aquatic inhabitants. Recommended usage involves maximizing water flow through the media in a canister filter, media reactor, or high-flow area.
