After a lot of use, spa water can start to look dull, smell a bit off, or just feel less fresh than it should. That’s usually a sign it’s time to shock. SpaGuard Spa Shock oxidizes the organic contaminants — think body oils, lotions, and other buildup — that regular sanitizers can’t fully break down on their own. A weekly shock treatment keeps your water fresh, your sanitizer working at full strength, and your spa ready to enjoy whenever you are.

•   Eliminates chloramines and organic buildup that cause dull, odorous water
•   Restores sanitizer efficiency and water clarity
•   Fast-dissolving formula — reentry time as short as 30 minutes
•   Recommended as a weekly maintenance treatment
