Abstract
A method and an apparatus for dispensing a pH balancing solution are provided. The apparatus includes a system having a chlorine generator with a power supply coupled to the chlorine generator, the chlorine generator servicing a body of water and chlorinating it. A pH monitoring and balancing unit is provided. The pH monitoring and balancing unit monitors and measures when power is supplied from the power supply to the chlorine generator to produce chlorine and thereby calculates an operational time for the chlorine generator. A pH monitoring and balancing unit controller is also provided, the pH monitoring and balancing unit controller computing an estimated pH level based on the production of the chlorine generator from the operational time measured and then determining if the estimated pH is outside of a desired range, and, if it is outside of the desired range, metering a discrete amount of pH balancing solution based on this estimated pH level to return the pH of the body of water to within the desired range.
