Product Description

SeaKlear Spa 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. Alkalinity Up allows you to easily boost your alkalinity levels into the optimal 80 to 140 ppm range, preventing corrosion damage as well as stabilizing pH.

Its quick-dissolving granular formula can be added directly to your spa or hot tub water, eliminating any need for messy dilutions or mixing. Spa Alkalinity Up also helps prevent dreaded “pH bounce,” which can make balancing your spa or hot tub water virtually impossible.

Best of all, Spa Alkalinity Up is made to the exacting standards SeaKlear demands of all its products, allowing you to buy with confidence.
