    imageHow often should I test and treat for phosphates? 1 Answer

    • After treatment, test phosphate levels monthly to ensure they remain low — the target is to keep phosphates below about 125 ppb for best algae control and sanitizer performance. Repeat treatment as needed based on test results.

    • Phosphates can enter your water from: Sunscreen and body oils Fertilizer runoff and grass clippings Decaying leaves and organic debris Makeup and hair products as well as fill water Once phosphates are present, they act as a food source for algae. High phosphate levels can contribute to cloudy water and algae outbreaks, even when other chemistry appears balanced.
