How long do I need to wait before I can use the pool?

Pool professionals usually advise that swimming be suspended for a 30-minute period after treating your pool. Never add Water Treatment products while the pool circulation pump is turned off; you will need to operate the circulation pump for a full 30-minutes after treatment. Under no circumstances add any water treatment products while the pool is in use.
If you are “Shock Treating” your pool with chlorine you should wait until the chlorine residual drops to below 5ppm before allowing the pool to be used. After shock treating your pool water leave your Pool Cover off until the Chlorine residual has reduced to 3ppm (parts per million).
