To raise low alkalinity and stabilize your pH, use sodium bicarbonate over a period of time.
What is the alkalinity of a hot tub?
The water Alkalinity or Total Alkalinity (TA) of your hot tub is a measurement of how your water can neutralize acids and as such is a key component to the balancing of your pH levels. The alkalinity levels act as a buffer to help your water resist drastic changes. If the alkalinity of your water is unbalanced, it can cause the pH readings to be either too high or too low. The alkalinity of your hot tub should be between 80 to 120ppm.
