Phosphates enter the pool water from multiple sources which may lead to increased algae growth and decreased chlorine activeness. Phos-Weekly will help to reduce phosphates in pool water. Phos-Weekly works in conjunction with Chlorine, Bromine, Simple Blue Manager, and Biguanide sanitation systems.
Directions for Use
Weekly dose: 1 capful (1 oz.) per 8,000 gallons
- Clean or backwash filter.
- With cap tight, Shake bottle well prior to application.
- With pump & filtration system running, add dose to skimmer.
- Run filter for 48 hours. Water may haze. Monitor filter pressure and clean or backwash as necessary according to manufacturer’s instructions.
Note: If filter pressure rises multiple times throughout the week and pool water is clean. A Phos-Away treatment may be needed. If make up water has high phosphate level, a stronger dose may be used.
