The purpose of shocking hot tub water is to break down the organic waste in the water. These contaminants can cause unpleasant odors and cloudy spa water. Shock treatments are essential for maintaining clear and clean water.
There are two types of shock treatments. They are classified as chlorine and non-chlorine. Each of these shock treatments has a different purpose. Using these treatments allows the sanitizer to perform at peak efficiency.
Chlorine Shock Treatment
Chlorine shock is normally used when the hot tub is first refilled and after heavy use. It is also used when the spa has been inactive for a period of time, or when it needs a boost of sanitizing. It can be used as a regular maintenance shock treatment, but a non-chlorine shock treatment is recommended.
Non-Chlorine Shock Treatment
A non-chlorine shock is a monopersulfate compound. Oxygen based shock has very little odor. A non-chlorine shock is normally used for regular, ongoing maintenance of the spa. It is compatible with other chlorine and bromine treatments.
Application amounts depend on use, sanitizer and the size of your spa. You can find details on the label of the product. Both types of shock treatment can be found at your local spa dealer.
