How to Reduce Pool Phosphates

What are phosphates?

Phosphates are food for algae. Although they are present in all water, once they reach a certain level they can cause issues in your pool. Phosphates can consume chlorine causing a consistently low level in your pool. When you have an extremely low chlorine reading, your pool can turn cloudy and/or green. Phosphates can also lead to scale formation on pool equipment, which can seriously damage your heater or salt cell. Phosphates are measured in parts per billion (ppb).

Where do phosphates come from?

Phosphates can be introduced into the pool through:

  • Source Water
  • Cleaning products and sunscreen lotions
  • After treating for algae
  • Lawn runoff after rain or watering
  • Construction
  • Fertilizers
  • Dead leaves (organic matter)
