A spa treatment system for maintaining spa water includes a spa that has a peripheral wall bounding an inner portion having water therein. An outlet and an inlet are each fluidly coupled to the inner portion. A water testing assembly is in fluid communication with the outlet. The water testing assembly is adapted for testing a pH level and an alkalinity level of the water. A plurality of containers is provided. A pump assembly is fluidly coupled to the inlet and to each of the containers for selectively pumping fluid outwardly of the containers as directed by the control in order to maintain proper pH and alkalinity levels.
