ABSTRACT:
An apparatus for purifying swimming pool water and inhibiting the growth of algae therein includes a substantially T-Shaped hollow pipe fitting having first and second opposing openings and a central opening subtantially normal to the first and second openings. The first opening is for receiving a flow of water and the second opening is for discharging the flow of water. A pressure fitting is coupled to and seals the central opening by a screw connection. An electrical anode, having cylindrical shape and consisting essentially of copper has a first major axis along the length of the cylindrical shape and is coupled to the pressure fitting and situated within the pipe fitting with its first major axis approximately normal to the flow of water. An electrical cathode assembly of four rods is disposed symmetrically about the anode. The cathode assembly is disposed adjacent the anode. A controller circuit applies an electrical current between the anode and cathode. A temperature sensor is coupled to the anode. A display displays a figure of merit relating to the current as a function of temperature. A control enables adjustment of the current so that another display reads the same as the first display.
