APPLICATION
Mix the recommended dosage with a bucket of pool water and evenly apply around the pool surface.
NOTE
For best results, dilute the amount of product needed with 1 gallon of pool water for every 10,000 gallons to be treated. Pour evenly over pool surface.
IMPORTANT
Turn off pool filter while product works throughout the pool water. After 12 to 24 hours, vacuum the cloudy water to waste. Then restart pool filter to remove what remains. Pool may be cloudy for a brief time while PR3 alters the phosphate into a form that can be filtered out. It is very important to monitor and maintain normal back pressure levels in pool filter.
