(c) a shared power supply for providing electric current to the first sanitizer generator and the second sanitizer generator; and

(d) a shared control system connected to the power supply, the first sanitizer generator and the second sanitizer generator for selectively delivering electric current from the shared power supply to the first and second sanitizer generators.

2. The system of claim 1 , and further comprising a first sensor located in the first circulation system, wherein the first sensor senses a parameter related to a sanitizer level in the water of the first body of water.

3. The system of claim 2 , and further comprising a second sensor located in the second circulation system, wherein the second sensor senses a parameter related to a sanitizer level in the water of the second body of water.

4. The system of claim 3 , wherein the control system selectively delivers electric current to the first sanitizer generator based upon a signal from the first sensor.

5. The system of claim 4 , wherein the control system selectively delivers electric current to the second sanitizer generator based upon a signal from the second sensor.

6. The system of claim 5 , wherein the control system comprises:

(a) a first flow sensor for sensing water flow through the first sanitizer generator;

(b) a second flow sensor for sensing water flow through the second sanitizer generator; and

(c) a control circuit connected to the shared power supply, wherein the control circuit controls delivery of electric current to the first sanitizer generator based on whether water flow is sensed by the first flow sensor, and wherein the control circuit controls delivery of electric current to the second sanitizer generator based on whether water flow is sensed by the second flow sensor.

7. The system of claim 1 , wherein the control system comprises:

(a) a first relay for controlling flow of current between the shared power supply and the first sanitizer generator based on need for sanitizer in the first body of water and water flow in the first sanitizer generator; and
