What is Total Alkalinity?
Total Alkalinity is one of the least understood yet most important component of keeping water chemistry in a hot tub balance.

Total Alkalinity (TA) is the buffer of pH in a hot tub.  This means if this measure is out of line, the pH readings may be off and pH may fluctuate more wildly, causing problems getting pH to balance in the 7.2-7.6 range.

Total Alkalinity readings should be between 80-120 parts per million (ppm).

Note that pH minus will lower the total alkalinity as well.

Side effects of Total Alkalinity out of balance

If TA is too high, then the sanitizer has to work harder, skin and eye irritation can occur, cloudy water and scale can form and the pH will be hard to control.

If TA is too low, then quick changes in the pH level can occur, corrosion and damage to seals and equipment are possible and skin/eye irritation can occur under acidic conditions.
