ABSTRACT:
In a swimming pool, or other open-to-sunlight water system, algae is controlled, as disclosed, by ionisation from a single metal, i.e., zinc. The zinc is mounted in a jacket that is built into the pipework of the pool, as a plurality of metallic zinc discs mounted in a plastic jacket or sleeve which is inserted into one of the circulation pipes for the pool. The sleeve is mounted to the pipe by pipe-to-sleeve adapters at each end thereof.
