1. A system for water purification of a pool or spa comprising:
- a container having a body of water therein;
an inline water circulation line for circulating water to and from the container;
a pump for circulating the water to and from the container through the inline water circulation line;
an optical sensor for periodically sampling water from the inline water circulation line and optically measuring a water characteristic of the sampled water wherein the measured water characteristic comprises a chlorine level, said sensor including a controller for determining if the sampled water is within a preselected range, said controller generating a dose signal if the chlorine level is below the preselected range and a no dose signal when the chlorine level is above the preselected range;
a rain sensor located proximate the body of water for changing a frequency of periodic sampling of the water;
an inline dispenser located in said water circulation line, said inline dispenser having a chamber therein;
a batch of solid water purification materials including chlorine and minerals located in the chamber of the inline dispenser;
a selector valve in said inline dispenser for manually controlling the flow of water through said chamber when water flows through said inline water circulation system to thereby maintain a fixed chlorine delivery rate to the body of water; and
a diverter valve located upstream of the inline dispenser, said diverter valve responsive to the no dose signal to change the fixed chlorine delivery rate by reducing the water dosed through the inline dispenser to thereby maintain the chlorine level in the body of water within the preselected range.

Abstract
A system for sensing and measuring water characteristics or an external factor and initiating controlling the water characteristics of the body of water which may be based on external factor where the controlling of the water characteristics can be achieved through dosing or nondosing of an inactive material through an active material or dosing both an active material and an inactive material in the body of water in response to measured levels of water characteristics to enable the water to be used for either internal or external use in controlling harmful organisms.

5. A dosing system for controlling a level of a halogen in a body of water comprising:
-
a dispenser; a batch of halogen in solid form located in the dispenser; an optical sensor for periodically measuring the level of the halogen in the body of water, said sensor including a controller for determining if the level of the halogen is within a predetermined range, said controller generating an output signal in response thereto if the level of the halogen is below the predetermined range; a diverter valve responsive to the output signal to dose water through the halogen in the dispenser to thereby elevate the level of halogen in the body of water; and a rain sensor for changing a frequency of periodically measuring the level of the halogen. - View Dependent Claims (6, 7, 8, 9)

10. A two-step system for water purification of a body of water located in a pool comprising:
-
a container having a body of water therein; an inline water circulation system for circulating water to and from the container; a pump for circulating the water to and from the container through the inline circulation system; a sensor for optically measuring a chlorine level of the body of water in the inline circulation system at a time interval; a controller to determine if the chlorine level is below a preselected range, said controller generating a dose signal when the chlorine level is below the preselected range and a no dose signal when the chlorine level is above the preselected range; a rain sensor for sending a signal to the controller to decrease the time interval between measuring the chlorine level when rain is detected; an inline dispenser located in said water circulation system, said inline dispenser having a chamber therein for flowing therethrough at least a portion of water from the inline circulation system; a batch of solid water purification materials including chlorine and minerals located in the chamber of the inline dispenser; a selector valve in said inline dispenser for manually selecting a flow rate of water through said chamber to thereby maintain a fixed chlorine delivery rate from the inline dispenser; and a solenoid valve located upstream of said inline dispenser, said solenoid valve openable in response to the dose signal and closeable in response to the no dose signal whereby the dose signal doses water into the inline dispenser to cause the inline dispenser to deliver both chlorine and minerals into the inline circulation system at the fixed chlorine delivery rate and the no dose signal prevents dosing water into the inline dispenser to prevent delivery of both chlorine and minerals to the inline circulation system.
