BioGuard Burnout 73 Shock

BioGuard Burnout 73 Shock is a superchlorinator for swimming pools. With the highest percentage of calcium hypochlorite of all the BioGuard shocks this one bag treats 16,500 gallons of water making it one of the strongest shocks on the market. Burnout 73 will effectively reduce organic contamination in swimming pool water resulting in increased water clarity.

Destroying organic contaminants* from the environment and bathers is important. Shocking your pool water is a needed step for proper pool maintenance. Shocks or oxidizers chemically destroy organic contaminants, remove combined chlorine and help restore water clarity. This is the second step of the BioGuard TruBlue Promise Program.

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.
