Chlorine Tabs 20 g
After the pool is filled with water or when the pool is to be used again at the beginning of the season, the pH value of water should be altered at first using pH MINUS or pH PLUS agents to the value between 6.8 and 7.6. In the case of hard water, its hardness may be stabilised with addition of WATER HARDNESS STABILIZER agent.
Then the first chlorinating with CHLORINE START is performed, all according to the instructions for use printed on the product packaging.
Then one piece of CHLORINE TABS 20 g per 3 m3 of water in the pool is put in the float or in the tablet dosing unit. This amount should be sufficient to maintain the necessary concentration of active chlorine in the water between 0.3 and 0.5 mg/l for 5 to 10 days depending on the factors affecting the amount of active chlorine in water, e.g. the air and water temperature, sunshine intensity and pool load. The correct active chlorine concentration and the right pH value should be checked regularly with a suitable tester. In order to prevent algae from occurring it is suitable to use ALGAE STOP in parallel. If the water quality suddenly deteriorates or if algae occur, one-time treatment of the water with CHLORSHOCK GRANULAR may be performed, all in accordance with the instructions for use printed on the packaging. CHLORINE TABS 200 g should preferably be used for pools larger than 10 m3.”
