Patent ID: 7381325

Claim:
An automated water testing and treatment system for a spa, said system comprising: a spa having a peripheral wall, an inner portion of said spa being bounded by said peripheral wall, water being positioned in said inner portion; an outlet being fluidly coupled to said inner portion; an inlet being fluidly coupled to said inner portion; a water testing assembly being in fluid communication with said outlet, said water testing assembly being adapted for testing a pH level and an alkalinity level of said water; a plurality of containers, each of said containers having bottom wall, a top wall and a peripheral wall being attached to and extending between said top and bottom walls, a plurality of spouts, each of said spouts being fluidly coupled to one of said containers; a pump assembly being fluidly coupled to said inlet and to each of said containers; a control being operationally coupled to said water testing assembly and to said pump assembly, said control selectively turning on said pump assembly such that fluid in one of said containers is pumped into said water, said control actuating said pump assembly and pumping fluid from a first one of said containers when said water testing assembly detects that a pH of said water is low, said control actuating said pump assembly and pumping fluid from a second one of said containers when said water testing assembly detects that an alkalinity of said water is low, said control actuating said pump assembly and pumping fluid from a third one of said containers when said water testing assembly detects that the alkalinity of said water is high.
