Seachem CupriSorb and Cupramine are designed to work together. With the Seachem Cupramine 250 ml you can effectively eradicate Oodinium, Cryptocaryon, Amyloodinium, Ichthyophthirius, and other ectoparasites of both freshwater and marine fish. It is superior to copper sulfate, chloride & citrate: it is non-acidic, less toxic to fish, remains in solution, and does not contaminate the filter bed. It is superior to chelates: it is fully charged (ionic), active at low concentrations, and is removable with carbon.

Once you have successfully treated your aquarium, you can remove the copper with Seachem CupriSorb 100 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.
