What is claimed is:
1.
A method of inhibiting the growth of algae in a body of water
comprising:
- directly adding to said body of water a water soluble source
of bromide ions in an amount sufficient to provide a concentration
of bromine to approximately 0.1 ppm to 100 ppm, adding directly to
said body of water a chlorine-containing oxidizer in amount
sufficient to oxidize said source of bromide ions to bromide at
the concentration specified and provide a concentration of
chlorine containing oxidizer of approximately 0.2 ppm to 10 ppm
sufficient to safely sterilize said body of water;
- said chlorine-containing oxidizer selected from the group
consisting of chlorine, an alkali metal hypoclorite or
trichlorotriazine trione, or sodium or potassium dichlorotriazine
trione;
- adding an alkali metal, alkaline earth metal, or ammonium
polyphosphate in proportions from approximately 5 to 15 weight
parts of said polyphosphate per each 100 weight parts of said
source of bromide ions; said polyphosphate being premixed with
said source of bromide ions prior to addition to said body of
water.
