Understanding Alkalinity

Total alkalinity measures the water’s ability to resist sudden pH changes. It acts as a buffer that helps stabilize your spa water chemistry.

Alkalinity is measured in:
ppm (parts per million)

Ideal Alkalinity Range:

80–120 ppm

Low Alkalinity (Below 80 ppm)

• Causes unstable pH levels
• Leads to constant chemical adjustments
• Makes water harder to balance

High Alkalinity (Above 120 ppm)

• Can contribute to cloudy water
• May reduce sanitizer efficiency
• Can cause discomfort to skin and eyes

Keeping alkalinity balanced helps create a more stable and enjoyable spa experience.
