We had the opportunity to sit down with Eric Knight of Orenda Technologies to discuss the Langelier Saturation Index also referred to as the LSI. This term may be brand new to you or you may have heard about it in a CPO class or even a start-up class, but it is definitely something that every pool professional should understand. We took one of Eric’s classes a while back and were very impressed with his knowledge of the subject. We knew we had to have him on to describe it the same way to you. We discuss how to calculate the LSI using the following six variables: ph, water temperature, calcium hardness, carbonate alkalinity, cyanuric acid, and total dissolved solids. Eric explains why each one is important and why you should be tracking the LSI on each visit. 

Eric works for Orenda Technologies which you may know for their products such as PR-10,000 or CV-600, but they have been stepping up their education game over the last year or so. They have spent thousands of hours creating Orenda Academy and have enhanced their app so that it not only works as a dosing calculator but also functions as a Langelier Saturation Index calculator as well. We encourage you to go through the academy if you haven’t already and attend any webinars or classes that Eric and the Orenda team put on. Knowledge is power and the more you know, the better prepared you are for what is out there in the field.
