ABSTRACT:
Recreational water, e.g., swimming pools, as opposed to industrial water, containing a source of free available halogen, e.g., chlorine, is treated with amounts of a 2-oxazolidinone, e.g., 4,4-dimethyl-2-oxazolidinone to thereby inhibit the growth of algae during the absence of biocidal amounts of free available halogen.
