In normal swimming pools with normal water quality, the residual chlorine in the water should be kept at 0.3-0.5mg/L, and the pH should be maintained at 7.4-7.6. Under this environment, bacteria and algae are not easy to grow and multiply.

After continuous rain, the residual chlorine of the water will generally not reach the standard, and the pH of the water will decrease, so that bacteria and algae have room for growth. Moreover, when the rain, the spores of the air, the lawn and the soil are washed into the water, and the bacteria and algae will multiply rapidly in the summer when the swimming pool has a high water temperature (usually at 28-30 degrees). The water in the pool turns green in a short time.

To solve this problem, follow these steps:

1. The first step is to add copper sulphate. The general addition amount is 1-2 times of the usual amount. This is because there are few algae in the water, and the algae are abundant after the water is green. Therefore, a sufficient amount of algicide (sulphuric acid) must be added. Copper) can fully kill algae. After adding the algicide (copper sulfate), the circulation system should be opened to make the agent as uniform as possible in the water, thus achieving the best results;

2. about 2 hours later, add trichloroisocyanuric acid disinfectant, the amount of addition is added per 1000 cubic meters of water plus 4kg (usually plus 2kg per 1000 cubic meters), which is what we usually talk about impact Treatment or superchlorination treatment to fully sterilize and disinfect the water in the swimming pool;

3. After about 2 hours, the pH value of the water is tested. Generally, it is rained and the disinfectant of trichloroisocyanuric acid is used. The pH of the water will definitely be low, so use a regulator that increases the pH (the Base).) The pH of the water can be increased by adding 1 kg per 1000 cubic meters of water to increase the amount by 1 degree. It is best to adjust the pH to 7.5;

4. Add precipitant at night, the amount of which is 5-8kg per 1000 cubic meters of water, so that fine algae and other suspended solids that have been killed in the water can be precipitated to the bottom of the pool;

5. The next day, use a suction machine to remove the sediment from the bottom of the pool. Through the above five steps, the water in the swimming pool can be cleared (Guangdong Hangyi Water Park Equipment Co., Ltd. m.reinventwithme.com)
