SpaGuard Total Alkalinity Increaser | Spa Balancer Brand_Hearthstone steady level of chlorine toSpaGuard Total Alkalinity Increaser is a concentrated granular product that raises low total alkalinity in spa and hot tub water. Total alkalinity is the unsung hero of balanced water it's the buffer that keeps your pH steady. When alkalinity is too low, pH becomes unstable and starts swinging unpredictably with every chemical addition and every soak. That swing has a name: pH bounce, and it's one of the most common sources of water care frustration.
