The Langelier Saturation Index is a calculation method used by pool and spa operators and water facility managers to indicate whether the water is in proper chemical balance. It has become an industry standard and universal benchmark used for all pools and water treatment technicians.
This app is designed for pool operators, pool service technicians, pool facility managers, water treatment managers, or home pool owners, giving you the tools to achieve properly balanced water in the palm of your hand.
Calculating water balance is the first step in solving water problems such as cloudy water. The saturation index incorporates the five balance factors, pH, total alkalinity, calcium hardness, temperature, and total dissolved solids. These are used to determine whether your water will be scale forming or corrosive.
