A pH that is too low or too high in your pool water can turn a simple dip into a real assault on your skin. Irritations, itching, red eyes… Discover why pH balance is crucial and how to control it to swim safely.
Why is the water's pH so important?
pH measures the acidity or alkalinity of water. In a pool, it should remain between 7.2 and 7.6 to ensure comfort and effectiveness of treatment products.
An unbalanced pH doesn't just affect water quality. Your skin, eyes, and hair also directly suffer the consequences.
The effects of a too-low pH on the skin
When the pH drops below 7, the water becomes acidic. The result: it irritates and weakens the skin barrier.
- Stinging and tightness sensation after swimming
- Appearance of red patches or itching
- Dry and brittle hair
This imbalance also accentuates the corrosion of equipment and makes chlorine too aggressive.
The risks of a too-high pH
A pH above 7.8 makes the water basic. This may seem less serious, but the effects are just as annoying:
- Red and irritated eyes after a few minutes of swimming
- Sensation of dry and rough skin
- Decreased effectiveness of chlorine, promoting bacteria and algae
Water with a too-high pH quickly becomes cloudy and uncomfortable for swimmers.
How to restore a balanced pH?
The solution involves regular testing with strips or an electronic tester. If the pH is too low, add pH Plus. If it's too high, correct it with pH Minus.
Some practical tips:
- Test the water at least twice a week during swimming season
- Adjust gradually, never all at once
- Check the pH after a storm, heavy use, or shock treatment
Sensitive skin: good habits after swimming
If you have reactive skin, adopt these simple habits:
Shower immediately after swimming, moisturize your skin with a suitable cream, and rinse your hair with clear water. These habits limit the effects of chlorine and unbalanced pH.
In summary
A pH that is too low or too high is not just a technical detail: it directly impacts your comfort and skin health. Keeping water between 7.2 and 7.6 is key to enjoying your pool without discomfort. Check regularly and adjust as needed to swim with peace of mind.
