Alkalinity Up for spas & hot tubs increases Total Alkalinity (TA) and will help bring pH up into the proper range, if pH is too low. Helps to reduce corrosion of metal parts and damage to pump motors and heaters. It also buffers to minimize pH bounce, and optimizes the effectiveness of bromine and other sanitizers. The Spa Choice formulation is fast dissolving and optimized for solubility in spa water.
Alkalinity Up is an alkalinity increaser which raises TA without raising pH to excessively high levels.
Product notes: Also called Spa Up, Alkalinity Increaser, or pH Buffer. Contains 100% sodium bicarbonate (also referred to as sodium hydrogen carbonate). pH 8.3
