Winter Pool Service

Winter Pool Service: Necessary or Not?

There are few certainties in life: death, taxes, deadlines, and homeowners who want to suspend or cancel pool service during the winter. We understand the logic behind suspending pool service, but we also know that the logic is based on incomplete information. As pool professionals, it is our responsibility to inform customers–homeowners who ultimately make the final decisions about their pool–about what cold water can do to their pool over the winter.

LSI Balance and Calcium Management | Pillar 1

LSI Balance and Calcium Management is the first of Orenda's Four Pillars. This is arguably the most important of the Four Pillars because it is about understanding water and how it behaves. This article aims to simplify chemistry, so it can be more easily understood. If you are a chemist (who is not already familiar with this subject) and you would like to get more in depth on the science of this topic, this is one of our primary sources. We will link to other external sources in this article as well. So let's get into it.

Understanding LSI: The Langelier Saturation Index

The Langelier Saturation Index (LSI) is a cornerstone of the Orenda program. The LSI is the unbiased measurement of water balance, as defined by calcium carbonate saturation. It determines if our water is aggressive/corrosive (low LSI), balanced, or scale-forming (high LSI). It sounds simple enough, but let's dive in and show you just how much it matters to other aspects of water chemistry.
