An improved method of controlling algal and bacterial pollution, as well as reducing the concentration of dissolved calcium, in a swimming pool, without the necessity of adding electrolytes thereto, involving the steps of: (a) conveying a stream of water from the swimming pool to an enclosed area and back to the pool; (b) providing a pair of spaced-apart electrodes in the enclosed area through which the water is to pass, the electrodes being chemically active and made from mixtures of silver and aluminum alloy containing from about 0.5 to about 5.0 per cent by weight silver and the valance being aluminum alloy; (c) providing a source of alternating electrolytic potential to the electrodes to generate an energy field through the water stream between the electrodes having an rms voltage range from about 25 to about 35 volts and a frequency of alternation of 60 cycles per second to toxify the bacteria and algae in the water and to agglomerate the dissolved calcium into filterable agglomerates; and, (d) providing a filter downstream from the electrodes in the enclosed area for filtering the water as it passes from the electrodes and before it returns to the swimming pool.
