The Common Causes of High pH Levels in Pools
There are several reasons why the pH levels in your pool may be higher than the recommended range. One of the most common causes is the use of chemicals, particularly those that contain high levels of alkaline substances. For example, adding too much sodium carbonate, commonly known as soda ash, can raise your pool’s pH levels significantly.
Another reason why your pool’s pH levels may be high is due to the use of hard water. Hard water contains minerals like calcium and magnesium that can increase the water’s pH levels. When you fill your pool with hard water, it’s essential to test the pH levels regularly and add the appropriate chemicals to keep the pH levels in check.
In some cases, high pH levels can occur due to the presence of algae and other organic matter. This can happen when your pool is not cleaned and maintained regularly. The organic matter can react with the pool water, resulting in an increase in pH levels.
Lastly, high pH levels can also be caused by a malfunctioning or dirty pool filter. A dirty filter can cause the water to become cloudy, and the pH levels can rise as a result.
Carbonates and bicarbonates are naturally present in pool water and can contribute to high pH levels. Carbonates are formed when carbon dioxide in the air dissolves in pool water, while bicarbonates are formed when carbon dioxide reacts with water. These compounds act as a buffer and help to keep pH levels stable, but when their levels get too high, they can cause pH to rise above the ideal range.
The primary source of carbonates and bicarbonates in pool water is the pool’s source water. Water from certain regions tends to have higher levels of these compounds than others. Additionally, the use of alkalinity increasers, such as sodium bicarbonate, can contribute to high carbonate and bicarbonate levels in the pool.
Another factor that can lead to high carbonates and bicarbonates in pool water is the use of chlorine. Chlorine can break down into hypochlorous acid, which reacts with carbonates and bicarbonates to form carbon dioxide. This reaction can increase the pool’s pH levels over time.
The Effect of High Alkalinity on Your Pool’s pH
Alkalinity refers to the ability of a solution to resist changes in pH levels. It acts as a buffer that keeps the pH level stable, preventing it from fluctuating too much. High alkalinity in your pool can cause the pH level to rise, which can lead to various problems.
If the alkalinity is too high, it can cause cloudy water and make it difficult to maintain the proper chemical balance in your pool. This can also make it harder to clean and maintain your pool.
High alkalinity can also lead to scaling, which is the formation of white or gray deposits on your pool’s surfaces. These deposits can be difficult to remove and can damage your pool over time.
In addition, high alkalinity can cause skin and eye irritation for swimmers, as well as affect the effectiveness of chlorine and other pool sanitizers.
To prevent high alkalinity, it’s important to regularly test and balance your pool’s alkalinity levels. This can be done with the use of alkalinity increaser or decreaser chemicals, as well as regular water changes.
The Influence of Chlorine and Other Chemicals on pH Levels
Chlorine is a common chemical used to sanitize pools, but it can also affect pH levels. When chlorine is added to water, it can increase the pH levels. This is because chlorine is a strong oxidizer and can release hydroxide ions into the water.
Cyanuric Acid is another chemical commonly used in pools to stabilize chlorine levels. However, high levels of cyanuric acid can lead to a rise in pH levels.
Muriatic Acid is often used to lower pH levels in a pool. This is because it is a strong acid and can neutralize the hydroxide ions in the water.
Baking Soda is another common pool chemical that can affect pH levels. Baking soda is an alkaline substance and can raise the pH levels in a pool. It is often used to increase alkalinity levels in a pool.
