What Is Chlorine Shock Treatment \u2014 and Why Daily Chlorine Isn\u2019t Enough ? <\/h2>\n

Shock treatment <\/strong>involves adding a high dose of chlorine at once to deeply cleanse the water<\/span>\u2014like a Big Cleaning Day for your pool.<\/span> <\/p>\n

Example of Chlorine Shock Reaction<\/strong><\/p>\n

The real culprit is chloramines. <\/b>When chlorine binds with sweat, sunscreen, or organic waste, it forms chloramines, which cause unpleasant odors, eye irritation, and reduced disinfection efficiency. Normal chlorine levels cannot eliminate them. Shock treatment breaks down chloramines chemically, removing odors and restoring fresh, hygienic water.<\/span><\/p>\n
