Why do you need to shock your spa?

Shocking a spa is done to destroy odors and eye irritating contaminates while boosting the effectiveness of your sanitizer (chlorine, bromine, or salt system). Sanitizers bind to bad things in your spa to destroy them and keep you safe. When you use oxidizer and “shock” your spa you break the sanitizer away from the bad stuff, allowing it to continue working without having to add more sanitizer to replace the amount that is bound to other things in your spa.
