Installing a swimming pool in your backyard is exciting. It adds a stylish place for relaxation and fun. With that being said, you first have to complete the process of having the pool installed. This involves excavation, pool tile selection, water supply, etc. Of course, the tough parts should be executed by professionals to ensure it is done correctly. Once the digging is done and the textures and tiles are in place, the swimming pool will be filled with water. This is a given; however, water’s relationship with pool textures is an actual science. As the pool owner, you will need to ensure they get along in order to solidify the lifespan of your new swimming pool.
Langelier Saturation Index
The Langelier Saturation Index calculates the level of saturation of calcium carbonate in water. The optimal level is 0.0 LSI, though a plus/minus of 0.3 is generally acceptable. A negative LSI indicates the water is undersaturated, which alerts the possibility of corrosion. A positive LSI, on the other hand, indicates oversaturated water, meaning the water could cause scaling (a buildup of inorganic materials found in pool shells).
Obviously, you want your swimming pool water as close to 0.0 LSI as possible. A 0.0 LSI means the water is at a perfect equilibrium. Furthermore, no corrosion and no scaling, resulting in a healthy and long-lasting swimming pool.
Calculating the Langelier Saturation Index
Hopefully we are not bringing back any nightmares from chemistry class, but the equation really is quite simple to calculate. It consists of six variables:
- Temperature (°F)
- Calcium Hardness (ppm)
- Alkalinity (ppm)
- Cyanuric Acid
- Total Dissolved Solids (ppm)
Equation: (pH) + (Temperature °F) + (Calcium Hardness) + [(Total Alkalinity) – (CYA correction factor @ current pH)] – (TDS factor) = LSI
(Equation per Orenda Technologies)
The point of the equation is to show you what exactly goes into the calculation and what all is measured to determine LSI. You won’t have to crunch the numbers yourself, but it is always good to have a base understanding so you know what questions to ask and so you can relate to an expert’s explanation when he/she advises of your pool’s LSI. Nothing is more frustrating than unknown technical terms being thrown at you, making your head spin.
Simply put, the closer to 0.0, the better. We don’t intend to confuse you; however, just like any product, you want to know its details and functions to ensure you use it correctly and can maintain it.
