SpaGuard Rapid Dissolve pH Decreaser Tabs are a product designed to quickly and safely lower high pH levels in spas and swim spas. These tabs contain a unique effervescing technology that helps disperse the treatment throughout the water, preventing issues like scale buildup and cloudy water that occur with high pH levels. The ideal pH range for a spa is generally 7.2–7.6, and these tabs are an easy, dry alternative to liquid acids for maintaining balanced water.
