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.
Nitrogen and carbon are also part of DNA. Unlike carbon and nitrogen, most of the phosphorous on Earth is stored in soil and rocks in the form of phosphate. Phosphate is one molecule of phosphorous surrounded by four molecules of oxygen, or PO43-. Plants can absorb phosphate directly through their roots. From there, it moves through the community in traditional fashion and back into the ground as animals die and decompose.
