Eliminate is a powerful broad spectrum fish treatment; acting against fungus, bacteria and a wide range of parasites including Chilodonella, Costia and Trichodina. In addition to being an effective anti-parasite treatment, pottassium permanganate can help with bacterial gill disease and skin ulcers. It will also oxidize organic matter and improve water quality and clarity. Directions: A large water change of 25% or more before treatment. Bypass biological filtration, turn off UV and increase circulation/aeration. Add 16 oz. to every 6,000 gallons of pond water. After treatment, the pond will have a pink hue for 4 hours. Eliminate may stain everything it comes it contact with. Gloves and eye protection should be worn.
