What does shocking a pool mean?
Shocking a pool or spa is the best way to keep it clean. It also prevents algae growth. Bacteria is often present in pools, entering from a variety of sources. Heavy storms, multiple bathers and waste from skin, hair, lotions, soap and more can contribute to the bacteria level of a swimming pool. Pool shock is a granulated form of chlorine used for water treatment. Shocking the pool is a necessary part of servicing it, as it disinfects the water. Many pool owners shock every few weeks, as part of their regular pool care routine, in order to keep everything clean and sanitary.Ê
