WTC Algae Control Formula (formerly known as Magna Bon) is a liquid algaecide that contains copper sulfate. It is not harmful to players and is completely odorless. Dilute 4 ounces of Magna Bon one gallon of water. Use a watering can or weed sprayer to go around the perimeter of your courts and other problem areas that show algae growth. One 2.5 gallon container should cover 3-4 courts. Apply monthly during the rainy season.
