Destroying organic contaminants, such as perspiration, suntan lotions, hair sprays, body oils, urine, pet dander, and cosmetics, from the environment and bathers is important!

Shocking your pool water is a needed step for proper pool maintenance. Shocks chemically destroy organic contaminants, remove combined chlorine, and help restore water clarity. This is the second step of the BioGuard 3-Step Pool Care System.

Isn’t shocking just for when your water has a problem?

No! Shocking should be part of your pool maintenance. While it does help with troubleshooting, when part of a routine, it removes contaminants that cause cloudy water and helps keep the water crystal clear and sparkling.
