Cuprisorb by Seachem

Controls Copper and Metals in the aquarium

For rapid copper removal in Fresh and Saltwater Aquariums.

Apsorbs faster than high grade carbon filtration, and is better suited for emergency situations or use after copper based medications have been used.

Will actually over time absorb copper that is present in gravel or substrate beds. Making once coppered systems safer for use as aquariums that can house invertebrates.
