Balancing your water is as important as adding your Sanitiser!
If you thought pH was important, you were right. But, Total Alkalinity is even more important. The Total Alkalinity is the buffer of pH, if it is not balanced correctly, the pH will not give you a correct reading.
Total Alkalinity is the ability to control pH. Total Alkalinity (TA) is a very important component of overall water balance. Its primary role is to help keep pH in proper balance. The best definition of TA is; “the measure of water’s ability to resist a change in pH.” In other words, once you balance your pH successfully within the range of 7.4 – 7.6, it is TA that helps you keep it there.
The secondary role of TA is to assist in providing the overall mineral content that all water requires to prevent unnecessary damage to surfaces. Water low in TA will see the pH bouncing up and down, almost uncontrollably. The spa surfaces will also be at risk of long-term damage due to corrosion, especially vinyl liners. Water high in TA will find the pH constantly high and in need of reducing and a greater risk of scale formation, cloudy water and shorter filter runs. Ideal TA Levels for All Hot Tub Surfaces: 125 – 150 ppm
