How It Works

Phosphates can enter pool water through rain, debris, fertilizers, source water, and swimmers. Since phosphates act as a food source for algae, removing them can make it easier to maintain clear water and reduce algae problems. Phosfree binds with phosphates so they can be removed through the pool filtration system.

Directions for Use

• Test phosphate level before treatment if possible
• Clean or backwash the filter before adding product
• Add the recommended amount directly to the pool with the circulation system running
• Run the pump continuously for at least twenty four hours after treatment
• Pool water may become temporarily cloudy as phosphates are removed
• After treatment, clean or backwash the filter as needed
• Retest phosphate level and repeat treatment if necessary

Application Notes

• For best results, follow label directions based on measured phosphate level and pool size
• Do not overdose beyond label instructions
• Routine maintenance doses may be used to help keep phosphate levels low
• Keep water balanced for best overall performance
