The stabilizer acts like a "sunscreen" for your chlorine. Without it, it degrades rapidly under UV rays.

  • Ideal value: between 30 and 50 ppm.

⚠ Too much stabilizer can impair the effectiveness of chlorine: test regularly.

 

 
 

 

 
 

 

 
 

 

 
 

AStabilizer too highIt can reduce the effectiveness of chlorine and prevent proper disinfection of pool water. When the level is too high, the chlorine becomes less active and algae or bacteria can develop more easily.

There is no product to reduce the stabilizer, so the solution is to drain some of the pool water and replace it with fresh water to dilute the stabilizer level.

Alkalinity is the first measurement to check. It acts as abufferto stabilize the pH. An incorrectly adjusted alkalinity leads to constant pH fluctuations.

  • Ideal value: between 80 and 120 ppm.
  • Advice: Always adjust the alkalinity BEFORE correcting the pH.

pH determines whether your water is acidic or alkaline. An unbalanced pH can damage equipment, irritate skin, or reduce the effectiveness of chlorine/bromine.

Ideal value: between 7.2 and 7.8.

Disinfectant kills bacteria and algae. Either can be used, but it's important not to mix them. A weekly shock treatment helps maintain optimal disinfectant levels and ensures clean, clear, and safe water at all times.

Target values:

  • Chlorine: 1 to 3 ppm.
  • Bromine: 2 to 4 ppm.

🔄 Never apply a shock treatment without first testing and adjusting alkalinity and pH.

Disinfectant kills bacteria and contaminants. Chlorine and bromine are both good options, but either can be used, but it's important not to mix them. A weekly shock treatment helps maintain optimal disinfectant levels and ensures clean, clear, and safe water at all times.

If bromine levels are too high, there is no specific product to lower them in a spa. The best solution is to remove the cover for a few hours to allow the bromine to evaporate naturally. It is also possible to replace some of the water to reduce the concentration more quickly.

Target values:

  • bromine: 1 to 3 ppm.

🔄 Never perform a shock treatment without first testing and adjusting alkalinity and pH.

Water hardness measures the level of calcium in the water. Water that is too soft becomes corrosive, while water that is too hard leads to limescale deposits.

  • Target: 200 to 300 ppm.

💡 This is particularly important to monitor in areas where the municipal water is naturally soft.

 

 
 

 

 
 

Excessive calcium hardness can cause limescale deposits to form on pool walls, equipment and filtration system.

Unlike other water parameters, there is generally no product to directly reduce calcium hardness. The solution is rather to drain some of the pool water and replace it with fresh water to dilute the calcium level and restore a proper water balance.

FAQ



The only effective way to reduce an excessively high stabilizer level is topartially drain the pool and refill it with fresh waterToo high a stabilizer level makes chlorine much less effective, which can lead to green water, persistent algae, and overconsumption of products.



Add the stabilizer (cyanuric acid) directly into the skimmer. Let the filtration run continuously until completely dissolved, which may take several hours or days. Then retest and adjust as needed.



The stabilizer must be kept between30 and 60 ppmBelow 20 ppm, chlorine breaks down too quickly in sunlight. Above 80 ppm, it becomes less effective, which can make the water difficult to clarify.


The main function of a stabilizer is to protect chlorine from UV rays. Without it, up to 90% of chlorine can disappear in a few hours under the sun. By adding a stabilizer:

- You keep a sufficient amount of active chlorine for longer.

- You reduce the frequency of chlorine additions.

- You ensure constant and effective disinfection.

Be careful, however: too much stabilizer can make the chlorine less effective. This is why it is important to follow the recommended dosages and test the water regularly.
