Do I Need To Add Chlorine To My Pool In The Winter

You can maintain a swimming pool successfully by adding the proper amount of chlorine. This chemical will help remove algae and bacteria from the water.


What is the perfect chlorine value for my swimming pool?

On the one hand, the pH value should be between 7.2 and 7.6. In addition, you have to keep the chlorine content at the right level. Ideally, the chlorine value should be between 1 and 1.5 ppm.

During the swimming season, we often recommend checking the water quality values twice a week. This method works by using a manual test kit.


Chlorine shock treatment

If you want to enjoy your swimming pool for the first time or start up the pool again after the winter, you have to get the chlorine content up to the right level. N.B.: Before you do this, it is best to first check the pH and chlorine values.

If the chlorine value is (almost) 0, it is best to carry out chlorine shock treatment.


When should you carry out chlorine shock treatment?

  • When using a swimming pool for the very first time
  • After the winter period
  • After a holiday period in which the water quality has not been checked
  • After a busy weekend of swimming with a lot of people in the pool.

The chlorine content in the pool drops during these periods. Since this process can take a long time, you should not add more chlorine to the pool. However, if the chlorine level gets too low, you should perform chlorine shock treatment.


How to perform chlorine shock treatment?

  • Before adding chlorine, the water should have the right pH value. It should be between 7.2 and 7.6.
  • Pour the chlorine powder into a bucket of water and distribute evenly across the swimming pool.
  • For chlorine shock treatment, 3 measuring cups of 40 grams of chlorine granules should be added per 10 m³ of water. This should be added after swimming and in the evening to prevent the product from spreading.
  • Also make sure the water is filtered after you have added the chlorine. This will improve the effectiveness of the chlorine in the swimming pool.
  • At regular intervals, check the chlorine content of water to ensure that it is at its optimal level. The ideal value is between 1 and 1.5 mg per litre of water (> 1 ppm and < 1.5 ppm).
