At water temperatures above 20 °C, germs and bacteria multiply significantly. The higher the temperature, the faster this occurs. To prevent these effects, oxidizing agents are used in the form of stabilized organic chlorine products or based on active oxygen. These substances eliminate germs and bacteria, thereby disinfecting your pool. Ideal chlorine level: 1.0-3.0 mg/l. The oxygen content should be above 5 mg/l. Quick-chlor granules are a fast-dissolving granule, specially designed for continuous or additional chlorination, as well as for raising the free chlorine content and for shock chlorination.
