Water disinfection
Understanding disinfection
Water disinfection is an essential stage in the maintenance of a swimming pool, whether private or public.
Because of their effective disinfectant properties, chlorinated products are widely used in this process.
What type of chlorine
For your swimming pool?
- Stabilised organic chlorine products are the most commonly used disinfectants in private swimming pools. These products contain a stabiliser that plays a crucial role in limiting the degradation of chlorine by UV rays, heat and high water circulation.
- Non-stabilised inorganic chlorinated products are preferred for public pools.
The level of stabiliser in the water must be carefully controlled. Under ideal conditions, the stabiliser concentration should remain below 75 mg/L to avoid disrupting the disinfection process.

Preserve the quality of your pool
With disinfected and disinfecting water
- When chlorine, bromine or salt come into contact with the water, they eliminate the bacteria, algae, viruses and fungi present in your pool. The water is then disinfected.
- But they will also remain partly available in the water, ready to act on new bacteria. The water here is a disinfectant.

Stabiliser management
Finding the perfect balance
As you use your pool, stabiliser can build up in the water. If the level of stabiliser becomes too high, it can interfere with the disinfection process, making your pool less hygienic. In such cases, it is necessary to change the water in your pool to restore the balance.
There are a wide variety of stabilisers available on the market, each adapted to specific needs.
Did you know?
To limit water changes, treat your pool with products with a high chlorine content (>92%) and in the middle of the season, switch to non-stabilised chlorine (PCH).
Choosing the right product
Depending on your pool
Disinfecting your pool is essential if you want to enjoy swimming in complete peace and safety. But you need to choose the right disinfectant for your pool to avoid any problems or imbalances.
Depending on the size of your pool, the type of liner, the sensitivity of your skin, your floating diffuser or skimmer equipment... It's important to choose the right product.
Each product is indicated with a dosage to be respected to guarantee optimal disinfection and eco-responsible management of your pool. If you have a pool of more than 50m3, Ocedis recommends the 500g pebble, but if you have an above-ground pool, opt for the 20g tablets.
| Types of disinfectants | Dissolution | Usage |
| 250 or 500 g pebbles | slow | for regular maintenance over several days |
| 20 g tablets | fast, easy dosage | for shock disinfection |
| Granules | immediate | for shock disinfection |
Regular chlorine, shock chlorine
When to use them
If your pool is green, you can start with a shock treatment using shock chlorine, then keep the water clean with regular stabilised chlorine or bromine.
It's best to consult your pool specialist for advice on the best disinfection plan for your pool.
