How to Remove Algae Growth in an Equine Stock Tank

High quality water is critical for the health and well being of a horse. According to North Dakota State University, sedentary horses require about 7 gallons of water a day while lactating mares, or horses that work up a sweat can consume up to 18 gallons per day. Growth of algae makes the water unappetizing to the horse, reducing its consumption, which may cause health problems. Algae-tainted water may even have toxic properties; so it's important to remove algae promptly, when it's found in your horse's stock tank.

Instructions

    • 1

      Clean the water tank often. Drain the water from the tank and wash the interior with a 10 percent bleach and water and solution. Rinse the tank with clear water before filling it with water for the horses.

    • 2

      Add copper sulfate, sometimes called bluestone, to the water. Follow the manufacturer's instructions on commercial products; but one teaspoon of copper sulfate commonly treats up to 1,500 gallons of water, making it a product more suitable for large tanks.

      Sprinkle baking soda on the water tank. Start with a couple of teaspoons and monitor the tank. If algae continues, add more baking soda. Baking soda is not considered as effective a deterrent to algae as cleaning and copper sulfate.
