Sirona Spa Down is a granular pH and alkalinity reducer formulated specifically for hot tubs and spas. High pH and alkalinity are common in spa water due to aeration, high temperatures, and frequent chemical additions. When left uncorrected, they can cause cloudy water, scale buildup, reduced sanitizer efficiency, and bather discomfort. Spa Down works quickly to lower elevated pH and total alkalinity, helping restore proper water balance and improve overall water quality. The fast-dissolving granular formula distributes evenly and allows for precise control without overcorrecting when used as directed. This product is ideal for routine spa maintenance or corrective treatment when test results show elevated pH or alkalinity. Why Lowering pH & Alkalinity Matters High pH causes both comfort and equipment issues. Why this matters: Restores proper pH balance Lowers total alkalinity Improves sanitizer effectiveness Helps prevent scale formation Enhances bather comfort Designed for Spa Water Conditions Sirona Spa Down is engineered for high-temperature spa environments, where pH tends to rise rapidly due to water movement and aeration. It works effectively with chlorine or bromine sanitizers and helps stabilize water chemistry when used as part of a consistent maintenance routine. Because spas have a smaller water volume, precise adjustment is critical—this formula allows for controlled, predictable results. Protects Equipment & Water Clarity Balanced pH and alkalinity help protect heater elements, pumps, jets, and plumbing from scale buildup and corrosion. Proper balance also improves water clarity and reduces surface staining, keeping spas looking and operating their best. The product is safe for spa surfaces and equipment when used according to label directions. Application & Service Notes Add directly to spa water with circulation running. Typical uses include: Correcting high pH levels Reducing elevated alkalinity After water testing indicates imbalance Retest water after circulation and make adjustments as needed.
