Pool shock is primarily used to sanitize swimming pool water, but its strong oxidizing properties allow it to be used for a few other specific purposes related to pool maintenance. These uses always revolve around its sanitizing and disinfecting capabilities.
Here are some other uses for pool shock:
-
Sanitizing Pool Equipment: Shock can be diluted and used to sanitize pool equipment such as nets, brushes, and vacuum heads to prevent the spread of algae and bacteria back into the pool. Be sure to rinse thoroughly after sanitizing.
-
Emergency Algae Treatment: While algaecides are typically used to treat algae, a large dose of pool shock (specifically calcium hypochlorite shock) can be used to kill green, yellow (mustard), and black algae blooms. This is often referred to as "shocking" the pool.
-
Removing Chloramines/Combined Chlorine: Chloramines are formed when chlorine bonds with contaminants in the pool water, like sweat, urine, and oils. These chloramines cause eye and skin irritation and a strong chlorine odor. Shocking the pool breaks down these chloramines, improving water quality.
It is important to note that pool shock should only be used for these purposes when related to pool and spa maintenance. It is not a general-purpose cleaner or disinfectant and should be handled with care, following all safety precautions outlined on the product label.
