Laguna Blue Arrow Pool Chemicals, 1 kg

Laguna Blue Arrow is a highly effective chlorine product for very quick and efficient shock disinfection of pool water. Laguna Blue Arrow is used for shock disinfection of pool water with a rapid decrease of excess chlorine from the water and the possibility of swimming in a very short time after treatment.

Usage:
The product is used for rapid chlorine disinfection of pool water when there is a strong microbial contamination. Dosing causes a visual change in the pool water and the removal of colored turbidity.

Instructions for use:
After filling the pool or before disinfection treatment of the water, always check and adjust the pH value to 6.8 - 7.6. Then pour the required dose of the product (granules dissolved in water in a plastic container) into the skimmer or directly into the pool with the filtration system turned on. After treatment, measure and, if necessary, adjust the pH value again. Until the product is perfectly mixed by the filtration system, it is necessary to exclude the presence of people in the pool! Chlorination is recommended to be done in the evening. The next day, add Laguna chlorine tablets. Use Laguna Blue Arrow especially during high use, at higher temperatures, or when there is an algae problem. It is essential to maintain the active chlorine content within the range of 0.3 - 0.8 mg/l and pH 6.8 - 7.6. At elevated water temperatures, the active chlorine content can be temporarily increased to 5.0 mg/l. Check chlorine content and pH value once a week using testers (Laguna 4-in-1 tester or Laguna pH/chlor tester).

Dosing:
10 - 20 g (10 g = 1 level tablespoon) per 1 m³ (1,000 liters) of water. This amount will increase the chlorine content in the pool water to a level of 7 - 10 mg/l.

Warning:
“Use biocides safely. Before use, always read the label and product information!"
