About Total Alkalinity
What is Total Alkalinity?

Total Alkalinity (TA) measures the water's ability to resist pH changes. It acts as a buffer, preventing rapid pH swings.

Recommended Ranges
  • Vinyl/Fiberglass: 80-120 ppm
  • Plaster/Gunite: 100-150 ppm
  • Optimal: 100 ppm
Effects of Low TA

pH bounce, metal corrosion, eye/skin irritation, and staining.

Effects of High TA

High pH, cloudy water, scale formation, and reduced chlorine effectiveness.
