If you own a salt pool, you may have noticed that your pool’s pH levels rise quickly, and despite regular chemical treatments are always high. This is because the salt cell generates chlorine gas, which increases the pH levels in the water. In this blog post, we’ll explain why high pH in a salt pool isn’t good and the relation of sanitizing power of chlorine with pH, and how Clearwater Pool Systems’ pH Pure product can help control pH in salt pools.
Why High pH is Bad for Chlorine Pools
Chlorine is one of the most used sanitizers for swimming pools. It works by killing bacteria and other microorganisms in the water. However, the effectiveness of chlorine is greatly affected by the pH levels in the water. As the pH increases, chlorine becomes less effective at killing bacteria and microorganisms, which can lead to algae growth and other water quality issues. In addition, high pH levels can cause scaling on pool surfaces and equipment, which can lead to costly repairs.
How Salt Pools Increase pH
Salt pools generate chlorine gas through a process called electrolysis. When water passes through the salt cell, an electrical charge is applied, which splits the salt molecules into sodium and chlorine. This chlorine gas dissolves in the water and becomes hypochlorous acid, which is the active sanitizer in the pool water. However, the process of generating chlorine gas can also increase the pH levels in the water. This is because chlorine gas is basic, and when it dissolves in water, it can raise the pH levels.
pH Pure: A CO2 Injection System for pH Control
To maintain proper pH levels in a salt pool, it’s important to regularly test the water and add acid as needed to lower pH levels. However, this can be a time-consuming and costly process, especially for large pools. Clearwater Pool Systems has developed a solution to this problem with their pH Pure product, a CO2 injection system that helps to control pH levels in salt pools.
pH Pure works by injecting CO2 into the water, which lowers the pH levels and helps to maintain a more stable pH range. This not only improves the sanitizing power of the chlorine in the pool, but it also helps to prevent scaling and other water quality issues caused by high pH levels. pH Pure is easy to install and maintain, and can be used with any size of salt pool.
If you own a salt pool, it’s important to be aware of how chlorine gas can increase pH levels in the water. High pH levels can negatively impact the sanitizing power of chlorine, as well as cause other water quality issues. Clearwater Pool Systems’ pH Pure product provides an effective solution for maintaining proper pH levels in salt pools, improving the efficiency of chlorine, and promoting better water quality.
