Swimming pool water treatment in Alsace: how to keep the water clear?
To fully enjoy your pool, it’s essential to maintain clean, clear, and properly balanced water. Green water, cloudy water, limescale, or a strong chlorine odor are often signs of a pH imbalance, insufficient filtration, or unsuitable treatment.
Aqua Conception, a swimming pool specialist in Alsace and the Bas-Rhin region , assists you with the maintenance and treatment of your swimming pool water .
Why is my pool water turning green?
Green pool water is usually due to the development of algae, encouraged by insufficient disinfection, an unbalanced pH or inefficient filtration.
To restore clear water, it is advisable to:
- analyze and correct the pH;
- brush the sides and the bottom;
- clean the filter;
- to perform appropriate shock treatment;
- maintain filtration during treatment.
If the problem persists, a more complete water analysis can identify the cause before adding new products.
What to do when the pool water is cloudy?
Cloudy water can be caused by suspended particles, a clogged filter, or insufficient disinfection.
Start by checking the pH and disinfectant levels , then clean the filter and skimmer baskets. If necessary, a clarifier compatible with your filtration system can be used.
Whitish and hard water: how to react?
Whitish water with rough walls may indicate the presence of limescale deposits , especially when the pH is too high.
It is then recommended to check the pH and water hardness, and then correct the balance. The walls can then be cleaned with equipment suitable for the pool liner. A limescale treatment also helps to limit new deposits.
Why does my pool smell so strongly of chlorine?
Contrary to popular belief, a strong chlorine smell does not necessarily mean there is too much chlorine in the pool.
It can be linked to the presence of chloramines or an unbalanced pH. It is then necessary to check the pH, free chlorine, and combined chlorine levels in order to adjust the treatment accordingly.
Is the water green or brown after treatment?
If the water turns green or brown after the addition of a disinfectant while remaining transparent, this may be due to dissolved metals , such as iron or copper.
A water test can confirm their presence before using a specific treatment compatible with the pool and its filtration system.
