Abstract
A process for the reduction of undesirable levels of algal growth in salt water bodies in which an effective amount of treatment water is added at the surface of the salt water body. The treatment water has a salinity and density either greater or less than that of the water at the surface of the salt water body. As a result, algae which have become accustomed to the existing conditions of salinity and density undergo rupture of cells and settle to the bottom of the salt water body, if the water density has been decreased, or suffer lower reproduction rates, and eventually flocculate and settle to the bottom of the salt water body, if the water density has been increased.
