Understanding the Langelier Saturation Index

Text us a pool question!

In this episode of the Talking Pools podcast, hosts Steve and Wayne delve into the critical topic of water balance in pools, focusing on the Langelier Saturation Index (LSI) and its importance in maintaining pool health. They discuss the key parameters that affect water balance, the significance of regular testing, and the challenges faced by pool professionals in calculating and maintaining proper water chemistry. The conversation also touches on the differences between commercial and residential pool maintenance, the role of cyanuric acid, and the impact of temperature on water balance. Listeners are encouraged to engage with the hosts and share their experiences and questions regarding pool care.
