Pool maintenance after rain

It is generally rainy in central China, so the weather will have a great impact on the water quality of the swimming pool. The main reason is that the air is polluted, and the rainwater is acidic. When a large amount of rainwater flows into the swimming pool, the pH value of the entire swimming pool will drop and become acidic; Rain will cause part of the water to flow into the swimming pool from the outside, bringing in various algae and bacteria; at the same time, the most rainwater will dilute the disinfectant so that it has no disinfection effect. The water temperature in summer is very suitable for the growth of various bacteria and algae. It becomes muddy, green, serious and even smelly. After the rain, we must deal with the water quality in time to prevent the water quality from deteriorating. Generally, the following steps are followed: 1. Put in the disinfectant first, and add 1.5 to 2 times the usual amount; 2. After two to three hours, Add PH regulator until the PH value reaches 7.5; 3. Add algaecide; 4. It is best to use filtration during the treatment process; agent). Poolking is the best swimming pool equipment manufacturer and supplier in China.
