Directions for use:Start treatment with as large a water change as possible or start with new water. Be sure to condition water so ammonia, chlorine and chloramines are removed. Do not stop filtration, but remove activated carbon and stop foam-fractionation (protein skimming) and UV sterilization.
Shake vigorously before use. One (1) teaspoon treats 32 gallons of water (1oz. treats 200 gallons). Distribute around the edge of the pond or directly in to the filter box to achieve the best overall distribution. A single treatment lasts 5-7 days. Repeat fish medication as necessary, but no more than once every 3 to 5 days. May be used as a preventative treatment when fish disease is likely. Do not use with other drugs or disease treatments. May cause temporary foaming. 16oz treats 3200 gallons.
