Chlorine-type chemicals are most commonly used in pools for sanitation. The water could be contaminated due to various reasons either by human beings or through any environmental process. Few people believe that the addition of chlorine to the pool may increase the risk of swimmers but it is necessary to add chlorine to prevent illnesses related to waterborne such as diarrhea and other skin infections.

Generally, it is advised to wait nearly 20 minutes in case of adding other water balancing chemicals, whereas, in the case of chlorine, it is safer to wait for almost 4 hours. This also depends on the size of the pool and the amount of chlorine added. The chlorine level in the pool should be below 5 ppm to avoid any type of risk involved. In few areas, swimmers are not allowed until one complete turnover of the water.
There are other treatments like shocking a pool which requires more amount of chlorine than usual, which will take a longer period to filter out the chlorine. Shocking treatment is required only when the pool contains algal blooms. In case of a more serious condition, the longer you have to wait to swim. It is a good practice shock to the pool either in the evening or at night without any sun rays.
If non-chlorine shock treatment has been used, the pool can be used immediately after the shocking treatment. This treatment should be carried out once in 2 weeks. In the case of chlorine tablets, you can swim even in presence of tablets in water. Before proceeding to swim, test the chlorine level with the help of any kit.
