Hot summer swimming pool must be where you most want to go. When you swim in the pool, have you ever wondered why there is a slight smell in the pool? Why is the water in the pool blue and the color blurs as the water becomes darker? Why The pool water can always be clean? So many people swimming in the pool how to ensure the health of water? Now I will use the physical knowledge we have just learned and will learn the chemical knowledge to the students answer.
