Total Alkalinity
Total Alkalinity measures the amount of alkaline substances in the pool water. Alkaline substances buffer your water against sudden changes in the pH. When the total alkalinity is too low, the water will corrode metal fixtures including copper components found in gas heaters and electrical heat-pumps.

Low total alkalinity could also cause staining and weaken your vinyl liner, causing it to wrinkle. The total alkalinity should measure 80 ppm for swimming pools using granular chlorine, or 100 – 120 ppm for swimming pools using stabilized chlorine such as chlorine tablets.

pH
pH refers to the intensity of acid or alkaline materials in your pool water. pH is measured on a pH scale extending from 1 (extremely acidic) to 14 (extremely alkaline). A pH of 7.0 is considered to be neutral. High pH (higher than 7.8) can cause eye and skin irritation, reduce the sanitizing action of chlorine, and cause the water to appear cloudy. Low pH (less than 7.2) can cause eye and skin irritation and corrode metal fixtures including copper components found in gas heaters and electrical heat-pumps. The pH should measure 7.2 – 7.8.
