From Norlex- Pool & Spa
Chlorine granulate non-stabilized and easily soluble for shock treatment and continuous disinfection. The chlorine granulate can be used in all types of swimming pools both for daily chlorination and for occasional shock treatment (does not form chlorine lock).
Instructions of use
- Stabilized water: 20-30 g per 10 m3 of water every 1 or 2 days.
- Non-stabilized water: 30-50 g per 10 m3 of water every day (divided into 2 equal doses morning and evening).
- Shock treatment/presence of algae: 50-80 g per 10 m3 of water. After a shock treatment the pool should not be used for several hours. Dosages may vary widely (sunlight, bathing load etc.).
- Maintain the chlorine level between 1 and 2 ppm in stabilized water, and between 0,5 and 1 ppm in unstabilized water.
