BioGuard CLC3 ( CLC 3, 8 LB)
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 predissolving. Safer to store and handle because it features an improved fire safety profile that meets NFPA criteria for a Class 1 oxidizer. Pre-dissolving required.
