Phosphates and Chlorine Demand DEFINING PHOSPHATE: Phosphates are compounds of the nonmetallic element phosphorous and are an essential nutrient for plant growth. According to the lake and pond industry, nitrates, phosphates and carbon are primary foods for algae growth. Phosphates are salts of phosphoric acid. Phosphoric acid is produced when Phosphorus is dissolved in water. Phosphorus in the soluble orthophosphate form is utilized for plant growth. The greater amount of phosphates in the water, the more sever the algae growth. Where do Phosphates come from? Ø Decaying plant material, from leaves and seedlings Ø Fertilizers Ø Mineral treatment chemicals Ø Rain Ø Ground water run-off Ø Bird droppings Ø Bather wastes (urine & sweat) Ø Dogs Ø Dead skin cells Ø Metal removers & sequestering & chelating products Ø Laundry detergent Ø Fill water Phosphate issues only become a problem when chlorine is stressed out due to the typical chlorine demand such as parties, rain, water imbalance, etc. You should have a phosphate test preformed at the beginning of each season; this can ward off excessive use of chlorine during the season. For high levels of phosphates above 5,000 ppb, partial draining of the pool may be necessary. For lower readings, a good phosphate removal product may do the trick. We have researched the product lines that are available in today’s market extensively for controlling and eliminating phosphates and have found the perfect product that is safe and has the maximum effectiveness without causing dramatic changes in pH.
