Peroxide is safe and easy to use, and you shouldn’t have any trouble using it to disinfect the water. This is true, but there are still certain rules. Cleaning the water in the pool with hydrogen peroxide will be effective only with strict compliance with the recommendations concerning both the concentration of the substance and the temperature of the liquid. It is also important to consider the degree of contamination of the pool and its volume.
For preventive purposes, 200-300 grams of hydrogen peroxide 30-40% or 100-150 grams of 60% substance per 1 cubic liter of water is recommended. The time of action, in this case, is 12 hours, after which you can use the facility for its intended purpose.
