A method and apparatus for purifying water includes a pump and purification cell, the cell having two electrodes, at least one of which electrodes is approximately 92 percent copper, 3 percent silver and 5 percent nickel, by weight. An electrical potential is developed between the electrodes and caused to alternate in polarity to prevent plating. Copper and silver ions are released into the water at adjustable rate, where they cooperatively destroy bacteria, algae, and the like.

A method for purifying a body of water, comprising the steps of: circulating the water over two electrodes, the electrodes being solid bars, the water being circulated in a discontinuous path defined by an enclosure for the electrodes, at least one of the electrodes being wired to ground potential through a resistor, at least one of the electrodes comprising an alloy of: approximately 85% to 93% copper, by weight; approximately 1.5% to 5% silver, by weight; approximately 2.5% to 7% nickel, by weight; simultaneously releasing copper ions and silver ions into the circulating water at concentration levels which are effective to substantially reduce algae and bacteria levels, but which are substantially less than the levels otherwise necessary to be so effective when released independently, by developing an electrical potential between the electrodes, whereby the water may be purified without need for chlorine treatment; and, sensing and indicating fouling of the electrodes by monitoring the potential of the electrode wired through the resistor, fouling being detected by a drop in said potential.
