Use weekly, if no algae is present: Use 1 ounce of Phosphate Remover per 5,000 gallons to maintain phosphate levels at or below 125 ppb (parts per billion). If algae is present: Shock the pool. Brush pool surface and vacuum to filter. Test water using a phosphate test kit. Use dosage chart to determine correct dosage. With filter running, disperse the proper amount of Phosphate Remover by adding it slowly around the edge of the entire pool and in front of the return line. Run filtration system for at least 24 hours. Watch the filter pressure and clean or backwash as necessary. Test for phosphate again.
- Eliminate phosphates from fertilizers, rain water, soaps and other pollutants.
