Abstract

Algicides are added to water for the algicidal treatment of the water, especially swimming-pool water. The disadvantages of known methods can be avoided or reduced if chlorohexidine or a salt thereof is used as algicide. Chlorohexidine and its salts are distinguished by a broad spectrum of algicidal action at very low concentrations of use.
