What raises and lowers individual pool chemistry factors?

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 Causes High Alkalinity in Pools?

Have you ever managed a swimming pool where the alkalinity level fluctuates? Usually, alkalinity decreases each week due to acid use, but what about an alkalinity level that rises? Those of you with CO2 feeders are probably already familiar with a seemingly endless rise in alkalinity. If you have ever wondered why alkalinity sometimes climbs on its own, this article is for you.

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.
