Understanding the best methods to balance your pool’s water chemistry is crucial for maintaining a safe and enjoyable swimming environment. Two common methodologies used in the industry are Range Chemistry and the Langelier Saturation Index (LSI).
The LSI method incorporates various chemical factors in pool water, such as temperature, pH, total alkalinity, calcium hardness, and total dissolved solids.
Range Chemistry, a practice dating back to the 1920s, emphasizes maintaining specific levels of certain chemicals like pH, total alkalinity, calcium hardness, and chlorine within a defined range. This helps keep the water safe and comfortable for swimmers. Despite its simplicity and widespread use, Range Chemistry doesn’t consider the complex interactions between various chemical factors in the water. These interactions can influence swimmer comfort and even impact the lifespan of your pool plaster and equipment.
On the other hand, the Langelier Saturation Index (LSI) offers a more holistic approach to balancing pool water chemistry. Originally developed in the 1930s for the water treatment industry, the LSI was later recommended by the Pool and Hot Tub Alliance (PHTA) in the 1960s for maintaining swimming pool water balance. Over time, LSI has gained acceptance and recommendation, especially in commercial pool operations.
The LSI method incorporates various chemical factors in pool water, such as temperature, pH, total alkalinity, calcium hardness, and total dissolved solids. By calculating the saturation index using the LSI, pool care professionals like us at Odin Pools can fine-tune chemical levels with greater precision. This results in a more pleasurable swimming experience and enhances the longevity of your pool plaster and equipment.
In essence, while Range Chemistry offers a basic yet effective method for balancing pool water chemistry, the Langelier Saturation Index provides a more comprehensive approach that considers the intricate interplay between different chemical factors in your pool water.
