Water Sanitation
The spa owner must regularly check and keep the spa water sanitized with scheduled maintenance (daily, if
necessary). Adding sanitizer or other chemical will control bacteria and viruses present in the spa water. The
maintenance of a proper water balance through appropriate use of sanitizers is the most important factor in
maximizing the life and appearance of the spa as well as ensuring clean, healthy and safe water.
Proper technique is important for water testing and treating the spa water. See your spa professional for
chemical, sanitizer, test kit and testing procedures questions.
