Disinfect the pool water, if necessary, using fast-dissolving chlorine granules. The disinfectant works best when you use it regularly right from the first filling. Suitable for shock treatment and maintenance disinfection.

Effect:
Granular disinfectant (granulate) for maintenance chlorination of pool water during the entire swimming season for both indoor and outdoor pools. Particularly suitable for one-time shock chlorination of very dirty pool water. Kills algae and viruses. As the granules dissolve, the pool water's chlorine concentration increases dramatically, which kills most common types of viruses and algae.

Manual:
Water remains clear and hygienically clean when its pH is 7.0–7.4 and its free chlorine concentration is 0.3–0.6 mg/l. When the water temperature is above 28 °C, the concentration of free chlorine should be up to 0.8 mg/l. If the chlorine concentration falls below 0.3 mg/l, the chlorine dosage must be increased. If the concentration of free chlorine is over 0.8 mg/l, do not use the pool. After filling the pool, add H2O Viikkochlor or H2O 3in1 Multi-Effective Tablet to the water as a preventive measure. If algae growth is visible in the pool, dose the amount of chemical suitable for shock chlorination. Important: Measure the pH of the water and the concentration of free chlorine with the help of the test kit, so that you know how to dose the granules correctly. Measure the pH and free chlorine concentration at least twice a week. Chlorine the water preferably in the evenings. When the pool is indoors: Take care of good ventilation in the pool area for about 24 hours.

Dosage instructions:
The basic dose is 100g (100g is 100ml) granules / 10 m3 (10000l) of water. For shock chlorination, use a maximum of 200g granules / 10m3 of water.

Dosage method:
Carefully dissolve the desired dose in water in a plastic bucket. ALWAYS ADD THE PRODUCT TO THE WATER, NOT THE VERSA! Pour the dissolved product slowly into the pool water or into the surface well of the pool (surface water purifier). The filtration system must be running during the dosing of the chemical and for 24 hours afterwards.
