Drop & Vac is a granular flocculent used to settle suspended particles and dead algae which cause cloudy pool water. Settled particles must be vacuumed out of the pool to restore water clarity.
Dosage and Directions for use:
Adjust pH to 7.8 and Total Alkalinity to above 100 ppm before adding Drop & Vac. Switch pump off and broadcast Drop & Vac evenly over the pool surface. Leave the pump off for 12 - 24hrs in order to allow suspended matter and debris to drop to the bottom of the pool. Vacuum to WASTE all the debris that has settled to the bottom of the pool.
