Langelier Saturation Index

Introducing the Langelier Saturation Index Calculator app for iOS – the ultimate tool for pool owners and professionals. With this app, you can easily and accurately calculate the Langelier Saturation Index (LSI) of your pool water, ensuring that your pool is always properly balanced and healthy for swimmers.

The Langelier Saturation Index is a measure of the balance between the calcium and alkalinity levels in your pool water. A balanced pool will have an LSI of 0, while a pool with too much calcium will have a positive LSI, and a pool with too little calcium will have a negative LSI. By regularly calculating the LSI of your pool water, you can ensure that it is always properly balanced and safe for swimmers.

Using the LSI Calculator app is simple: just enter the pH, temperature, total alkalinity, and calcium hardness levels of your pool water, and the app will provide you with an instant calculation of the LSI. You can even save your calculations and track the LSI of your pool over time to monitor changes and make adjustments as needed.

The LSI Calculator app is a must-have for anyone who wants to keep their pool water healthy and balanced. With its easy-to-use interface and accurate calculations, you'll be able to maintain a safe and enjoyable pool environment for you and your family. Download the app today and take control of your pool's water chemistry.

Also, water temperature can be entered as Fahrenheit or Celsius.
