SeaChem Cupramine ™ effectively eradicates ectoparasite of both freshwater and marine fish. It has all the advantages of copper sulfate and chelated copper, but not the disadvantages. Like copper sulfate, it is fully ionic and effective at low concentrations. The cupric (Cu+2) charge is fully active. Like chelates, it is safe for fish and is not precipitated in the filter bed. Unlike both, there is more than a 4x concentration gap between the minimal therpeutic dose and the toxic dose. Unlike copper salts, it is stable in the aquarium, and, unlike chelates, it is easily removed by chemical filtration. Unlike other copper products, it is both highly effective and safe in freshwater as well as marine water. It does not damage the filter bed. Cupramine™ contains 10,000 mg/L of copper and 100 mL treats over 500 gallons.
Remove all invertebrates. Turn off UV sterilizer; remove chemical filtration.
If the bottle has a dropper cap, use 16 drops (1 mL) per 40 L (10.5 gallons*) the first day, wait 48 hours, then repeat. On non-dropper caps, each inner ring is 1 mL. tIn freshwater use half dose. Final copper concentration is 0.5 mg/L (0.25 mg/L in freshwater). Leave at this concentration for 14 days. Do not redose without testing. Do not use in conjunction with any other medication. If tank has ever been treated with an ionic copper (e.g. copper chloride, sulfate or citrate), test copper level after initial dosing.
Although most fish tolerate Cupramine™ to 0.8 mg/L, it is not advisable to exceed 0.6 mg/L copper.
Remove with carbon.
Do not use in conjuction with ParaGuard™.
Test for copper with our MultTest: Copper™ kit. Marine or freshwater use.
