Ideal pH value: 7.0-7.6. Ideal chlorine value: 1.0 - 3.0 mg/l. For continuous chlorination every 7 - 10 days, use 1 tablet of 20 g per 10 m³. For refilling and shock chlorination, please use rapid chlorine tablets. Use only with a skimmer or dosing float. Never throw tablets directly into the pool due to the risk of bleaching. At higher temperatures or with increased exposure to bathers, the chlorine concentration should be checked more frequently. Warning: Never mix with other chemicals. Mixing with other chlorinating agents can cause violent reactions and explosions.
