Leaves and debris on the floor and surface will waste your chlorine’s killing power, as it attacks these organic materials, rather than the A-B-C problem that we are trying to correct. 2 Lower the pH. Chlorine is very sluggish at high pH levels. At a pH of 8.0, less than half of the chlorine you add to the water will convert to hypochlorous acid, the killing form of chlorine. Lower the pH to 7.2 before shocking. 3 Read the Label. We have 8 different types of pool shock, all with slightly different dosages. For some pool shock, dilution in a bucket is necessary to dissolve the granules, to prevent damage to pool surfaces. 4 Add the Shock. Distribute the granular chlorine throughout the pool surface, with the pool pump running. Be careful not to spill any on your clothing or the pool deck, and don’t broadcast it into the wind! 5 Brush the Pool. This helps to distribute the chemical, and removes the layer of dust and film on your pool surfaces, which may allow some contaminants to escape treatment. A good brushing, vacuuming and backwashing should follow an algae shock treatment.
