Why use slow chlorine

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.

Avis sur la clorodrine

Je m'en suis servi qu'une seule fois depuis mon achat, donc pas assez d'expérience à voir la saison prochaine.

Aucun pots abîmés

Contrairement à ma dernière commande, aucun pots n'étaient endommagés.
Concernant les pastilles de chrore, leur efficacité est bien supérieure à ceux du commerce.
