Alca-Plus raises the total alkalinity (TA) level of your spa water. A low TA level may cause the pH to fluctuate. It also causes spa water to be corrosive, which may result in staining and damage to the spa surfaces.
• Prevents spa and equipment damage • More stable pH value
• Improves flocculation
