SpaGuard’s Soft Soak Spa Sanitizer provides hot tub owners with a one-step treatment that replaces chlorine and bromine in your spa, yet effectively controls bacteria, softens the water for bather comfort, and removes strong chemical odors. Simply test your pool weekly after application with Soft Soak test strips, and add Soft Soak Spa Sanitizer when called for to maintain a clean, healthy spa environment.
