Directions

BEFORE APPLYING Zero Phos

Make sure all pool equipment is working properly, including pump, filter, skimmer, and heater.

 

To Reduce High Phosphate Levels

• Backwash and rinse filter according to manufacturer's instructions.
• Apply Zero Phos at a rate of one bottle per 10,000 gallons directly to water around the edges of the pool. For pools less than 10,000 gallons, do not exceed 16 fl oz in one treatment.
• Allow pump and filter to run continuously for 24-48 hours. Pool water may cloud upon addition, but will clear within 48 hours.
• After 48 hours, backwash and rinse the filter according to the manufacturer's instructions.

 

*If the filter pressure increases 8-10 psi above normal operating pressure, backwash and rinse filter accordingly.
