Sirona Spa Up is a granular pH and alkalinity increaser designed to raise low pH and total alkalinity levels in hot tubs and spas. Low pH water is aggressive and can cause corrosion of heaters, pumps, and metal components, as well as eye and skin irritation for bathers. Spa Up works quickly to restore proper pH balance, helping stabilize water chemistry and improve sanitizer effectiveness. The fast-dissolving granular formula allows for precise adjustments, making it ideal for routine maintenance or corrective treatment when water tests indicate low pH or alkalinity. This product is essential for maintaining comfortable, equipment-safe spa water. Why Raising pH & Alkalinity Matters Low pH can damage equipment and irritate skin. Why this matters: Prevents corrosion of heaters and metal parts Improves bather comfort Stabilizes sanitizer performance Helps maintain clear, balanced water Protects spa surfaces and plumbing Designed for Spa Water Conditions Sirona Spa Up is formulated specifically for high-temperature spa environments, where pH can drop quickly due to chemical use and water replacement. It works effectively with chlorine or bromine sanitizers and helps maintain consistent water balance when used as part of a regular testing routine. Because spas contain a smaller volume of water, accurate dosing is critical—this product allows controlled, predictable results. Supports Long-Term Water Balance Proper pH and alkalinity levels help prevent surface etching, metal corrosion, and water cloudiness. By correcting low readings promptly, Spa Up supports a healthier spa environment and reduces the need for more aggressive chemical corrections later. The granular formula dissolves rapidly in circulating water. Application & Service Notes Add directly to spa water with circulation running. Typical uses include: Correcting low pH levels Raising total alkalinity After testing indicates acidic water Retest water after circulation before making additional adjustments.
