The right pH level in your pool is one of the prerequisites for clear, healthy, high-quality water all summer long. Careless or incorrectly dosed maintenance products can quickly make water more acidic, or on the contrary, basic/alkalineor neutral. To find out the pH level in your pool, you can measure it with a pH tester.

Regulating your pool’s pH

Note that the ideal pH value for a swimming pool is between 7.0 and 7.6, depending on water quality. Consequently, a pool pH between 0 and 7 indicates acidity, while values above 7 indicate alkalinity, in other words basic water. A well-balanced pool pH helps maintain better water quality for longer. It helps limit the proliferation of bacteria in your pool, and keeps equipment such as fasteners, the lining of your shell pool, and the filtration system in top condition. Last but not least, the right pH value for your pool greatly enhances bathing comfort.

pH too high in your pool

If the pH level in your pool is too high, it means that your water is too soft and that
you need to rebalance it by adding pH min (pH reducer).

Low pH in your pool

If, on the other hand, you wish to correct the water and restore your pool’s pH to the correct level, you’ll need to use an alkalinity booster sold in specialist stores. This will raise the pH of your pool and make it more neutral.

So don’t forget that a regulated pH is essential to maintaining a healthy pool. It will help prevent the development of algae, microorganisms and dirt, so take care of your pool!
