Directions for use of Burnout 73 pool shock:
Shock Treatment / Superchlorination:
Adjust pH between 7.2 and 7.4 prior to shocking or superchlorination.
Add product directly to pool water. Do not pre-dilute in water. Keep pump and filter running.
Shock treatment should be done at night or during a period when the pool is not in use. This product can be added by spreading the dry granules over the surface of the water at the deep end of swimming pool while the pump is running.
Shock pool at least once a week during periods of heavy use.
Do not enter the pool until the free chlorine residual has dropped to 4.0 ppm or less. Between shock treatments, continue to maintain the proper water balance and sanitizer level in your pool.
