One aspect of water chemistry that often confuses people is the difference in alkalinity between spa water and pool water. In this article, we’ll explore the science behind this phenomenon and how it affects your swimming experience.

What is Alkalinity?

Alkalinity is a measure of the water’s ability to resist changes in pH. In other words, it’s a measure of how much acid can be added to the water before the pH level drops. This is important because maintaining a stable pH level is crucial for a healthy swimming environment. Low alkalinity can cause the pH level to fluctuate, which can lead to eye and skin irritation, corrosion of pool equipment, and an overall unpleasant swimming experience.

Alkalinity is measured in parts per million (ppm) and should be maintained between 80-120 ppm for most swimming environments.

Why is Spa Alkalinity Higher Than Pool Water?

  • Bromine – Spa water is typically sanitized using bromine, while pool water is often sanitized using chlorine. Bromine has a higher pH level than chlorine, which can lead to higher alkalinity in spa water.
  • Temperature – Spa water is typically heated to a higher temperature than pool water. Higher water temperature can cause the pH level to rise, leading to higher alkalinity.
  • Usage – Spas are smaller in volume than pools and are often used less frequently. This means that the water in a spa is exposed to less fresh water, leading to a buildup of minerals and alkalinity over time.

How to Maintain Proper Alkalinity Levels

To maintain proper alkalinity levels, it’s important to test your water regularly using a reliable test kit. If the alkalinity level is too low, you can add baking soda to the water to increase alkalinity. If the alkalinity level is too high, you can add muriatic acid to lower the alkalinity. However, it’s important to remember that these adjustments should be made slowly over time to avoid drastic changes in the water chemistry.

By understanding the chemistry behind your spa and pool water, you can maintain a clean and healthy swimming environment for you and your family. Now that you know the science behind alkalinity, you can take steps to keep your water balanced and enjoyable all year round.
