BioGuard CLC Classic

BioGuard CLC Classic is a multi-purpose granular chlorine that when used as needed, provides a residual source of chlorine to keep water clean and clear. It also works great as a superchlorination treatment for everything from cloudy water to high combined chlorine levels and algae growth. It is extremely easy to use and can be applied without the hassle of pre-dissolving.

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.
