I just had my water tested. They suggested to shock the pool. Since I beat around the bush on the BBB method. Can't I just put more bleach in, instead of buying shock?? My pool is 18x36 with a deep end. To open over three days I put 6 gallons of bleach in it. Yesterday I didn't do much other than run the pump. The water is teal, and cloudy after 1' deep. Thanks for all you help. Jason.
