|Now what's total alkalinity, and why do I have to test for it?|
This is the water’s ability to resist changes in pH. The same conditions that produce the need to Super-chlorinate may also affect your water’s total alkalinity. Keep total alkalinity at the proper level of 80- 120ppm. High alkalinity can cause cloudy water, staining, and scale formation. When total alkalinity is too low, there is corrosion and it is difficult to control the pH.
