In this article, we explain how alkalinity buffers pH. We focus specifically on the significance of pKa values in water chemistry and how they impact the buffering capacity against changes in pH.
When troubleshooting a swimming pool, it helps to know what can cause individual chemistry factors to increase and decrease. This article is an overview of the most common chemistries we measure in swimming pools, and what causes their levels to change up or down.
We have also included a Rule Your Pool Podcast episode for each factor we talk about in this article.
What should your calcium hardness be? What should your total alkalinity be? Are there ideal numbers? And if so, what are they for your pool? This article discusses these questions through the lens of overall water balance.
It happens all the time. Swimming pool pH climbs, or sometimes spikes, and all sorts of problems like calcium dust and carbonate scale can occur. But what causes high pH in pools? Why does the pH sometimes climb, and other times stay relatively steady? In this article, we will discuss pH and how it shifts, and offer some remedies to correct the pH, based on each situation.
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.
