Too little calcium in the water can cause corrosion, particularly in heaters and other metal components. To increase the hardness to the recommended level of 100-300 ppm, add a calcium hardness increaser such as Leisure Time Calcium Booster. Too much calcium can cause scaling on the walls and heating elements or cloudy water. To prevent calcium in the water from causing these problems, add a sequestering agent such as Leisure Time Spa Defender.
