TA-Total Alkalinity

  • TA is a measure of the ability of a solution to neutralize hydrogen ions, which is the measure of water's resistance to change in pH.

  • TA is the result of alkaline materials including carbonates, bicarbonates and hydroxides.

  • If total alkalinity is too low the pH may drop rapidly, causing etching and corrosion.

  • If TA is too high a high pH often occurs causing problems such as; cloudy water,     decreased disinfectant effectiveness, scale formation and filter problems.

  • For the typical swimming pool, TA should be maintained in the range of 90 to 140 ppm.

  • If you have a SWG, or you commonly run water features the TA can be kept on the low side, between 60 and 80.

  • Sodium bicarbonate also known as baking soda is used to raise the total alkalinity.
