Thinking of the perfect swimming pool and visions of sparkling water and happy swimmers likely dance in your head. Keeping this scene intact involves taking the proper steps to sanitize the pool and prevent any health or aesthetic problems. The water will then remain clear of algae, free of disease causing pathogens and users won’t complain about red eyes or chlorine smell.

Understanding the role of chlorine in maintaining safe water is not difficult once you learn the basics of pool chemistry.
