If you own a swimming pool, or are considering one, you’ll want to ensure it is well maintained so you can make the most of it for many years to come. An essential element of this is ensuring your pool’s water chemistry is balanced by maintaining the right pH levels. This blog explains how to get your pool pH levels right, ensuring crystal clear water and safe swimming conditions for everyone to enjoy.
Understanding pH
The pH level measures how acidic your pool water is on a scale of 0 to 14. A pH level of 7 is neutral, below 7 is classified as acidic and above 7 is alkaline. The ideal pH level for your pool water is between 7.4 and 7.6, as this aligns closely with the pH of human eyes, reducing the risk of irritation and making it more comfortable for swimmers.
A balanced pH is also important for extending the lifespan of your pool. Having your pool water too acidic or alkaline can lead to corrosion of pool equipment and surfaces, or the formation of scale, which can damage your pool over time. Other chemicals you are using to maintain the water chemistry, such as chlorine, also work more effectively when your pool water is in the ideal pH range.
Getting the right pool pH
Testing your pool’s pH
Once the pH in your pool is established, it should be checked weekly using a test kit, to ensure the levels remain in the correct range. Always collect a water sample at least 18 inches deep for the test, as surface water can give an inaccurate reading.
Adjusting your pH level
If the test results show your pool pH falls outside the 7.4 to 7.6 range, you should take action to adjust the levels. If your pH is too low, use a product like pH Plus to increase alkalinity, and if it is too high, use pH Minus. Once treated, leave it until the next day before testing the water again. Retreat if the pH level is still outside of the ideal range.
Maintaining the ideal pH
Keeping your pool pH level within the desired range isn’t a one-off task. Regular testing is required, especially during periods of heavy use or extreme weather. Making small adjustments as soon as the changes are discovered means your pH levels won’t get too far out of balance and cause bigger problems.
Problems with pool water chemistry
Usually, increasing the pH levels in your pool increases the total alkalinity. However, in some less common occurrences, the total alkalinity stays high, even when pH is in the right range. When this happens, chlorine will not work as effectively, and your pool will quickly turn cloudy. At this point, it is best to seek expert advice.
