Make sure your spa water remains as safe and healthy as can be with Sirona™ Spa Up. The granular formula raises the pH and total alkalinity levels in hot water to increase the effectiveness of your sanitizer as well as reduce the chance of equipment corrosion.
– Always maintain the pH of your spa water between 7.2-7.8. A low pH reading (below 7.2) can cause equipment corrosion
– Compatible with all sanitizers
