It discloses an algaecide composition prepared by reacting copper dioxide and a suitable copper salt such as copper carbonate in the presence of an alkaline substance. In this case, the solution is approximately 7.0
It is obtained in l)H of the application. However, the resulting solution contains only a relatively low concentration of elemental copper, on the order of about 4%.
