Reason: Soap components in bath products (mainly those low-grade cleaning products such as soap and detergent containing soap crumbs) stearic acid and calcium and magnesium ions in water form water-insoluble calcium and magnesium stearate. Because its density is less than that of water, it floats on the water surface, and after a period of time, it forms a pile with dirt at the edge of the pool. The main components are insoluble calcium carbonate and magnesium carbonate, which are harmless to people but affect their mood.
Solution:
1. Add alum to purify water.
2. The water purification system can automatically change water, so it is very convenient to clean the swimming pool and change water in the future.
It is mainly cleaned regularly, but this one used by everyone in the bathhouse doesn't work.
