The Langelier Saturation Index (LSI):
A Key Tool for Maintaining Pool Water Stability
Owning a pool is all about enjoying those refreshing dips and relaxing weekends, not stressing over water chemistry. But to keep that water sparkling and inviting, there’s one concept you need to understand: the Langelier Saturation Index, or LSI. Don’t worry, it’s not as complicated as it sounds!
What is LSI?
LSI stands for Langelier Saturation Index, a fancy term that helps you determine if your pool water is balanced. Balanced water isn’t too corrosive or too scale-forming, which means it’s safe for swimmers and kind to your pool equipment.
Here’s a simple breakdown:
• Corrosive Water – Low LSI. This can eat away at your pool surfaces and equipment.
• Scale-Forming Water – High LSI. This leads to unsightly scale deposits on your pool tiles and fixtures.
Why Should You Care About LSI?
Maintaining the right LSI helps you avoid costly repairs and ensures your pool stays inviting.
Having a balanced water:
✔ Protects Equipment – to reduce wear and tear on pumps, heaters, and filters.
✔ Keeps Water Clear – to prevent cloudy water and scaling.
✔ Enhances Swimmer Comfort – to ensure the water feels good on the skin and eyes.
How to Check and Adjust LSI
- Test Your Water – we regularly test for pH, alkalinity, calcium hardness, and temperature.
- Use an LSI Calculator
- Adjust as Needed
- Low LSI (Corrosive) – raise pH, alkalinity, or calcium hardness.
- High LSI (Scale-Forming) – lower pH, alkalinity, or calcium hardness.
Easy Tips for a Balanced Pool
- Regular Testing – Check your pool’s water chemistry weekly.
- Consistent Maintenance – Keep your pool clean and free of debris.
- Proper Circulation – Ensure your pool pump and filter are working correctly.
