Seachem Aquarium water cleaner Cupramine

Copper treatment for external parasites. Active at low concentration (does not precipitate). Attached to amine, less toxic to fish. Cupramine effectively eradicates Oodinium, Cryptocaryon, Amyloodinium, Ichthyophthirius andautres ectoparasites from freshwater and marine fish. It's better than copper sulfate, chloride and citrate: it's non-acidic, less toxic for fish, stays diluted (doesn't precipitate) and doesn't contaminate the bed filter. It is fully charged (ionic), active at low concentrations and removable with carbon. Cupramine is easily removed by chemical filtration. It is highly effective and safe in both fresh and seawater.
