Why use slow chlorine

Use slow chlorine to keep your pool clean and healthy.

Slow chlorine keeps the necessary chlorine concentration for permanent water disinfection and prevents the development of algae.

Use it with our app

You can free download our application on Apple Store (IOS) or Play Store (Android). Then you can follow advice from our recommendation engine to know when and how you can use our chemicals products.

How it works

When it comes into contact with your swimming pool water, chlorine is released and creates sub-components:

  • Active chlorine whose disinfectant effects are active;
  • Potential chlorine, the disinfectant potential of which will gradually be released over time and will therefore be transformed into active chlorine;
  • Chloramine, produced during the degradation of organic matter by chlorine.

Main advantages

  • High chlorine concentration;
  • High chlorine grade quality;
  • Dissolves well;
  • Quality/price ratio;
  • Treatment efficiency;
  • Good friability.

Usage advice

  • Check if pH is between 7.2 and 7.6;
  • Clean the skimmer of all impurities;
  • Place the chlorine pebbles in the skimmer;
  • Activate water filtration.
