Why use shock chlorine

Shock chlorine significantly and almost instantaneously increases the concentration of disinfectants in your swimming pool water. Its effectiveness is very important but of short duration.

Use-it with 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

On coming into contact with your swimming pool water, shock chlorine is released directly and degrades organic matter, disinfecting your swimming pool. The designation "shock" or "rapid" depends on the solubility of the chlorine. Very soluble chlorine will be called "shock" or "fast" chlorine because it is effective much faster (but also much shorter) than slow chlorine.

Main Advantages

  • High shock chlorine concentration;
  • High shock chlorine grade quality;
  • Fast efficiency;
  • Quality/price ratio.

 Usage advice

  • Activate the filtration of your swimming pool;
  • Dilute the shock chlorine in a bucket of water;
  • Incorporate the mixture of water and shock chlorine in your swimming pool.


  • Except at the start of the season and before wintering, the use of shock chlorine must be exceptional in the case of the normal use of the swimming pool, shock chlorine should be reserved as much as possible for the treatment of serious cases (heavy frequentation, breakdown, algae, etc.);
  • Use biocidal products with care, read the label and product information before use;
  • Authorization number n°4112 B;
  • This product is intended for the Belgian market only.

Transport catastrophique

Les produits sont très bien, mais ils arrivent trop souvent détériorés dans le transport.
Et sur cette commande c’était le pompon ! 2 sauts de 5kg complètement éventrées et répandu dans le carton. J’ai fait une réclamation il y a 5 jours sans retour de iopool pour l’instant
