SpaGuard Total Alkalinity Increaser is a professional-grade spa water balancer specifically formulated to raise total alkalinity levels in hot tubs and spas. Total alkalinity acts as a pH buffer, preventing rapid pH fluctuations that can cause cloudy water, equipment corrosion, and skin irritation. This 2 lb container provides multiple treatments for residential spas, making it an economical choice for regular maintenance. The active ingredient—sodium bicarbonate—works safely and effectively to stabilize your spa's water chemistry. When total alkalinity is properly balanced (ideally between 80-120 ppm), your pH levels remain stable, your sanitizer works more efficiently, and your spa equipment lasts longer. Show more
