Why use slow chlorine

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

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.

Indispensable super produit qui est de qualité

Christophe rioblanc

Après avoir terminé les galets que j'utilisais habituellement et qui fonctionnaient à merveille, j'ai voulu utiliser les galets recommandés par la sonde et l'application.
Malheureusement l'eau a rapidement tournée et je n'arrive pas à la rattraper, je vais devoir de nouveau acheter les autres galets et garder mes 5kg de galets iopool sur les bras. Je suis très déçu car l'idée et le système sont ingénieux...
