There’s nothing quite like a hot summer day by the pool: 90-degree weather, cold drinks, accessible shade, and zero responsibilities. For the swimmer, amenities like...

In our last article, we introduced the concept of the Mole, a unit of measurement that allows us to weigh atoms, ions, and more complex molecules. This article expands on that lesson to demonstrate how to read product percentages listed on chemical labels. In particular, we're focused on Chlorine %.

Metal corrosion is common in and around swimming pools, but what is corrosion? This article explains the chemistry and offers some examples. For a deeper dive into the science, you can read the full article here, where the focus is on indoor swimming pools and stainless steel corrosion. 

In swimming pools and spas, calcium phosphate scale is rare. But in the right conditions, it can form scale deposits that are harder to manage (and remove) than calcium carbonate. This article explains calcium phosphate, how it forms and precipitates, and how you can prevent it.

Every year, dust from the Sahara Desert in Africa travels across the Atlantic Ocean to the Americas, and it is vitally important to our global ecosystem. The nutrient-rich Saharan dust, abundant in phosphorus, nourishes the ocean's phytoplankton and algae, while also acting as a natural fertilizer for the lush Amazon rainforest. That same dust also gets into swimming pools.

It's a common belief that bright, sunny days lead to more chlorine loss in swimming pools than cloudy, rainy days. But is this really the case? We set out to investigate this theory. This article explains what UV does to chlorine, and the impact of clouds and cyanuric acid on chlorine photolysis.

For swimming pool owners and service professionals, understanding the role of Cyanuric Acid (CYA) goes beyond its basic function of protecting chlorine from sunlight degradation. This article explores the role of cyanurate alkalinity as a pH buffering system and how it influences the overall water balance.

In this article, we explain how alkalinity buffers pH. We focus specifically on the significance of pK_a values in water chemistry and how they impact the buffering capacity against changes in pH. 

Chlorine products have different pH values when dissolved in water, but their impact on the pH of a swimming pool is not always significant. This article discusses how each chlorine type impacts pH and why.

In this article, we will discuss the significance of the mole in chemistry and how it is applied to chemical reactions and products.

One of the most common mistakes in pool chemistry testing is testing a water sample that is too cold. Let's discuss why.

Of the three most common types of in-ground swimming pools (concrete, vinyl liner, and fiberglass), fiberglass pools are sold as having the least maintenance and risk of problems. For the most part, that's true. But as we will learn in this article, water chemistry still matters in fiberglass pools. Especially calcium hardness and overall LSI balance.
