Aquascape Fungus Treatment is used to treat fungal infections in pond fish. Common symptoms of fungal infections include white, green, or grey cottony-looking growths developing on pond fish. It is important to treat as soon as you identify an issue. Many issues can be linked back to poor water quality or the introduction of a sick or stressed fish. It is important to accurately dose any treatment. Please take time to calculate the water volume in your pond before adding this or any other water treatment. Discontinue the use of UV clarifiers/sterilizers or chemical filtration, including the use of carbon, zeolite, or ion exchange resins. Ensure proper oxygenation during treatment. Before adding any medication to your pond or holding system, make sure you verify all water parameters and rectify any issues before treatment. One 8-ounce bottle treats 1,250 gallons of water.
