Dosing of sodium hypochlorite in a backyard swimming pool.

Sodium hypochlorite – the common name for liquid chlorine or liquid chlorine – is one of the means of disinfecting pool water. Using sodium hypochlorite, we can disinfect both the water in the garden pool by the house and in large pools in sports centers, hotels, spas, etc.

There is no single rule of thumb for dosing sodium hypochlorite. The effectiveness of active chlorine in a solution depends on many factors, the most important of which are:

  • water pH,
  • water quality (amount of pollutants),
  • mineral composition of water,
  • temperature

Active chlorine is most effective at pH 7.0, so before disinfecting the water with hypochlorite, you should set the pH of the pool water between 7.0 and 7.4. During the first dosing use – for standard tap water – 200-250 ml of 15% sodium hypochlorite solution per 10,000 liters of water, then the losses of deactivated chlorine should be replaced every few days by adding 150-200 ml of 15% sodium hypochlorite solution.

It should be remembered that pool chemicals only support the purity of the water and not the golden mean for its maintenance. Regular filtering and collecting impurities are still necessary treatments. However, if the water in the pool is non-transparent (cloudy, milky, green, etc.), it means the need to use other pool chemicals.
