Directions for Use

Read entire label and use strictly in accordance with precautionary statements and directions.


Initial treatment

Clean or backwash filter following manufacturer’s directions. With the pump running add 1 quart of this product per 10,000 gallons of water, pouring product directly into the pool. Continue to run pump for 24 to 48 hours after this addition.


Maintenance treatment

For the maintenance dose, apply 16 fl oz of this product per 10,000 gallons of pool water once a month. Add product directly to pool water with pump on. Maintenance doses should be used for pools in areas where excessive hardness or metals cause constant scale and staining problems.


Removal of fresh stains

Many fresh (less than 5 days old) metallic stains can be removed by this product. Add this product at the rate of 1 quart per 10,000 gallons of water. Apply directly to the pool in the area of the stains. Brush the stained area daily for 3 to 5 days. Large metal stains may require repeat treatments. Where metal stains have aged into the pool’s surface, draining and acid washing is recommended for white plaster pools only. Consult your Pro Series dealer regarding this matter.
