For Start-Up or Initial Shocking: With pump running and pool not in use, broadcast 1 pound of this product per 10, 000 gallons of water directly into the deep end of the pool. To prevent possible damage to the pool surface, use a pool brush to disperse any granules that may have settled at the bottom of the pool. Repeat procedure after 24 hours if needed, to establish a chlorine residual of 1-3 ppm as determined by a test kit. For Routine Shocking: Every 2 weeks with the pump running and pool not in use, broadcast 1 pound of this product per 10, 000 gallons of water directly into the deep end of the pool.
