Why is Total Alkalinity important?
Total Alkalinity is the measure of the ability of water to resist changes in pH. In other words, Total Alkalinity is like an anchor for keeping pH where it should be. If the Total Alkalinity is not properly maintained then the pH will become increasingly difficult to keep in the recommended range of 7.2 – 7.8. When this happens the water can become out of balance, affecting chlorine’s ability to kill bacteria and causing corrosion, staining, scaling, and eye/skin irritation. This is why we maintain all pools according to the Calcium Saturation Index.
