What does active oxygen mean in practice?
The preparation oxidizes some of the pollutants without the characteristic chlorine smell, but its level and durability depend on the composition of the product.
When does it matter?
Not every chlorine-free system provides full disinfection on its own at high temperatures and heavy loads of bathers.
Which solutions are related to it?
The manufacturer's complete program is used, pH and filtration are maintained and the correct ingredient is measured with a dedicated tester.
