INTRODUCTION
Phosphorus is an important nutrient for aquatic plants. The amount found in water is
generally not more than 0.1 ppm unless the water has become polluted from waste water
sources or excessive drainage from agricultural areas. When phosphorus is present in
excess of the concentrations required for normal aquatic plant growth, a process called
eutrophication takes place. This creates a favorable environment for an increase in algae
and weed nuisances. When algae cells die, oxygen is used in the decomposition and fish
kills often result. Rapid decomposition of dense algae scums with associated organisms
give rise to foul odors and hydrogen sulfide gas.
