and prevent it from turning green
a number of parameters need to be analyzed when treatment of your pool. These parameters include pHthe alkalinity level or chlorine content. For example, it should be between 1 and 1.5 ppm (parts per million), equivalent to 1 mg/l.
When the chlorine level in your pool is insufficient, simply add more until it reaches the ideal level. On the other hand, when the
chlorine is too high, several solutions solutions are possible.
The problems causeds by overdosing your pool with chlorine
Use a chlorine shock dosage per m3 is necessary to increase the chlorine level in your pool. But when the concentration is too high and you don’t act quickly, an odor is released and problems can arise on :
- Swimming pools and their equipment pH is directly linked to chlorine levels. The higher the latter, the lower the pH and the more acidic the water. Acidic water has a highly corrosive effect on pool surfaces, such as the liner or the shell of your pool.
- Bathers Their eyes, skin and respiratory tract can be irritated by high levels of chlorine. high chlorine levelsbut also when the water’s pH, alkalinity or hardness are out of balance.
How to reduce chlorine in a swimming pool?
You have checked your chlorine level after a shock treatment and you realized it was too high? Now you’re wondering how you can lower it?
The first thing to do is stop adding chlorine, turn off the chlorinator and remove the chlorine pebbles from the skimmers.
Then you can…
Let the sun’s UV rays work naturally
When you observe excess chlorine (up toto 4 ppm, for example), one of the best reflexes is to leave your pool open. In fact, to reduce chlorine levels, there’s nothing like the sun’s UV rays and good filtration to lower the chlorine content. chlorine treatment.
Your pool water is very sensitive sensitive to the sun’s UV rays. Chlorine molecules are 90% destroyed in around two hours on a sunny, cloudless day. This will improve water quality, eliminate product odors and prevent technical problems.
Renewing pool water
Another solution for reduce free free chlorine (i.e. all the chlorine present in the water, including active and potential chlorine) is to drain part of your pool.
The chlorine concentration will decrease, as will pH and alkalinity. On the other hand, by neutralizing chlorine in this way, you will have to carry out new analyses and therefore potentially incur a additional chemical costs.
This solution is therefore not the most advantageous for maintenance, but you can, at the very least, wash/rinse the filter, add water to reach 2/3 of the skimmers and restart filtration.
Apply a chlorine-neutralizing product
Use a chemical neutralizer to regulate your chlorine shock treatment is a quick solution quick and solution as long as you follow the instructions on the product labels. Otherwise, your pool could be deprived of chlorine.
Chemical neutralizers for pond maintenance include, for example sodium thiosulfate. This powder is diluted directly in water to neutralize any trace of chlorine in the water.
It should therefore be used with caution to avoid significantly reducing chlorine levels. Depending on the m3 of water and chlorine mg/litre of chlorine to be neutralized, an average of 1 à 2,5 g of sodium thiosulfate.
Once the chlorine level in your pond has returned to normal, you hope it won’t go back up again any time soon. To do this, don’t hesitate to equip yourself with the right tools and products, such as a electronic tester to check the different rates and prevent these risks. In addition automatic dispensers like a
are used to automatically distribute chlorine in pools, evenly and at low doses.
You can also switch to
which offers many advantages, but also needs to be monitored.
