“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.
We need to come together and understand how calcium behaves in water. Let’s start by debunking a myth in the pool business: calcium is NOT your enemy! It is actually your best friend. Yes! Calcium does amazing things for water chemistry, and helps pool owners and operators balance their pools according to the LSI. The LSI (Langelier Saturation Index) is a measurement of calcium carbonate (CaCO3) saturation in water. Too much (high LSI over +0.30) can lead to calcium falling out of solution as scale. Too little (low LSI below -0.30) means your water is aggressive and looking for calcium to consume. This is the cause of etching, corroded pool equipment and many other problems.
When the pool is properly balanced with calcium, other factors of water chemistry become surprisingly easy to manage. Factors like pH and total alkalinity seem to stay more consistent. Understanding how calcium behaves means we can predict and control it. Say goodbye to scale and etching!”
“Swimming pool temperature impacts the water chemistry in a big way. This article will outline a few reasons why.
Pool Temperature and Water Quality
Let’s divide “water chemistry” into two different categories, and start with water quality:
Warmer water means more chlorine demand. This isnot due to sunlight degradation of chlorine, though summertime does mean more hours of direct sunlight hitting an outdoor pool. The real reasons for higher chlorine demand are because both living and non-living contaminants are more prevalent in warmer water. Algae and bacteria, for instance, are living contaminants that chlorine must kill (sanitization). Warmer water means those microorganisms can reproduce more rapidly, therefore problems like algae are more prevalent in the summertime. If you have a pool, you have probably already know this…” –Orenda Technologies
“Have you ever asked “what’s the difference between pH and alkalinity? Many of us in aquatics confuse total alkalinity and pH. It’s understandable, given how blurred the line is between words like “alkaline” and “alkalinity.” Indeed, alkalinity and pH in water chemistry are closely related, but they are not the same. This article will distinguish between them.” – Orenda Technologies
