LSI first, range chemistry second

What if range chemistry is the wrong thing to focus on when managing water? What if the ranges do not always apply, like in the winter? Theoretically, the textbook ranges for chemistry are ideal. But in reality, that's not always the case. In this article we will explain why we prioritize the Langelier Saturation Index (LSI) first, and range chemistry after that.

What is Alkalinity?

Total Alkalinity (TA) often gets confused with pH and words like alkali and alkaline. This topic is widely misunderstood in the pool industry. Most of us know how to test for TA, but may not know what it actually is, what it does, and why it's important.

What is Carbonate Alkalinity?

The LSI calls for the carbonate alkalinity of pool water...but this is a confusing term. Pool chemistry test kits only measure Total Alkalinity (TA). So what is Carbonate Alkalinity? And how is it different from TA?

Total Alkalinity vs. pH, and their roles in water chemistry

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.
