why is the ph level important in my pool?

​Maintaining the proper pH level in swimming pool water is essential for the health and safety of swimmers. A pool’s pH level is a measure of its acidity or alkalinity, and it is important to keep it within a certain range for several reasons.

Firstly, a pool’s pH level affects the effectiveness of chlorine and other sanitizers. If the pH is too low (acidic), the chlorine will be used up more quickly, and if the pH is too high (alkaline), the chlorine will become less effective. This can lead to unsafe swimming conditions as the water may not be adequately sanitized, increasing the risk of waterborne illnesses and infections.

Secondly, the pH level affects the comfort of swimmers. If the pH is too low, the water can be irritating to the eyes, nose, and skin, causing redness and discomfort. If the pH is too high, the water can feel “hard” and leave a residue on the skin.

So, what is the ideal pH range for swimming pool water? The recommended range is between 7.2 and 7.8. This range is slightly basic, which means the water is slightly alkaline. This is the optimal range for chlorine to work effectively, and it is also comfortable for swimmers.

If the pH level is outside of this range, it can be adjusted using pH increaser or pH decreaser products, which are readily available at pool supply stores. It is important to follow the instructions on these products carefully, as adding too much can lead to further imbalances and potentially harmful conditions.

It is important to note that you should make sure the alkalinity is balanced properly before you adjust the pH. If the alkalinity is low (acidic), then the pH will not give a true reading - so no matter how much you adjust the pH up or down that you use - you won't be balancing the water properly.

Regular testing of the pool’s pH level is also essential to ensure it remains within the recommended range. This can be done using a pH test kit, which measures the acidity or alkalinity of the water. Testing should be done at least once a week, and more frequently during periods of heavy use or extreme weather conditions. Square One Pool Service offers at-home water testing and balancing as low as $25.

In conclusion, maintaining the proper pH level in swimming pool water is crucial for the health and safety of swimmers. By keeping the pH within the recommended range, the water will be properly sanitized and comfortable for swimmers. Regular testing and adjustment of pH levels can help ensure a safe and enjoyable swimming experience.
