Introducing Orenda's Four Pillars of proactive pool care. This episode is the first of a four-part series, in which we discuss the importance of the Langelier Saturation Index (LSI). It is the unbiased metric of water balance, and the Orenda calculator app is helping us understand how to use it and why it is so critically important in water chemistry.
00:00 - Intro
01:32 - Origins of the Orenda App's LSI calculator
02:47 - Traditional "RANGE CHEMISTRY" vs. the LSI
04:31 - Why pools in different areas may need different chemistry parameters to satisfy the LSI
05:03 - What is the Langelier Saturation Index (LSI), and its six factors?
06:20 - What does the LSI actually tell us?
08:00 - Calcium hardness is NOT the leading factor that causes scale
16:18 - What does colder water temperature do?
16:54 - You can have ideal range chemistry and still be out of LSI balance
18:54 - Distinguishing between Carbonate Alkalinity and Total Alkalinity
21:22 - The LSI reigns supreme, and LSI violations occur at a local level
23:45 - The action step for Pillar 1: Keep LSI balanced year-round
