Place coral specimen in dip for 5-10 minutes, depending on severity of problem. In very severe cases, a double dose may be used. With clear and accessible lesions, dip concentrate may be painted on lesions directly before placing in dip. Observe animals during treatment for evidence of adverse reactions such as excessive sliming. Prepared dip solution may be used for up to a day, but should then be discarded.
