Blue arrow LAGUNA 1kg
Blue Arrow Laguna is a highly efficient chlorine preparation for very rapid and effective shock disinfection of pool water after pool filling or strong algae occurrence. The advantage is the rapid loss of excess chlorine and thus the possibility of swimming in a short time (after several hours) after water treatment. Always check and adjust the pH to 6.8 -7.6 after filling the pool or before disinfecting the water. Then pour the required dose of the product (granulate dissolved in water in the plastic container) into the skimmer or directly into the pool with the filter device on. Measure again and adjust pH if necessary after treatment. The presence of people in the pool must be avoided until the product is thoroughly mixed with the filtering device! Chlorination is recommended to be performed in the evening. Next day, add Laguna Chlorine Tablets. Apply Laguna Blue Arrow especially during increased traffic, higher temperatures or problems with algae. It is necessary to maintain the active chlorine content in 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 briefly increased to 5.0 mg / l. Check chlorine content and pH once a week with testers (Laguna 4in1 tester or Laguna pH / chlorine tester).
Dosage:
- 10 - 20 g (10 g = 1 equal tablespoon) per 1 m3 (1000 liters) of water
- The amount of chlorine in the pool water is increased to 7 - 10 mg / l
