To keep your pool clean and safe, use pool shock regularly. Pool shock is a special powder or granules with chlorine that helps clean the water. It helps get rid of dirt and germs, making the pool water clear and safe to swim in.
When you use pool shock, it adds a lot of chlorine to the water, which helps remove stuff that makes the water cloudy. Things like sweat, oil, and urine can mix with chlorine and create something called chloramines, which smell bad and can irritate your eyes, skin, and lungs.
Shocking the pool means adding enough chlorine to get rid of these chloramines and keep the pool fresh and clean.
