Non-additive that cleans and sanitizes the walls of the tank and plumbing, not the water. It's free of bleach and chlorine, and leaves no smell or taste. Fresh Water Tank Sanitizer utilizes a chemistry similar to those commonly used in restaurants, food processing plants and medical facilities to sanitize drinking glasses, food preparation equipment and other hard surfaces. When used as directed, it kills bacteria, Staphylococcus aureus (Staph), Eschericia coli (E-coli), Listeria and other microorganisms on surfaces to eliminate odors and sanitize tanks, lines and hoses.
