Phosphate is a vital plant nutrient and the presence in swimming pool water, even at low concentrations, can cause accelerated algae growth in poorly maintained pools. Pools, that are properly maintained, usually do not have unexpected difficulty controlling algae, even in the presence of phosphates.
Phosphates are the food supply for algae, thus high phosphate levels promote algae growth. When you introduce phosphate reducers into your water, such as Natural Chemistry PHOSfree 2 L, it cuts off the food supply for algae, which can, in turn, lead to cloudy water (filled with dead algae).
