Step Two: Measure Your Water and Pool Shock
Measure out exactly one gallon of water into your raw water storage container. As reminder, 128 ounces is one gallon. After the water is in the container, add one level teaspoon of calcium hypochlorite.
Put the lid on and shake the mixture to make sure all of the pool shock is evenly distributed. Make sure that you never put the shock in before the water.
