I am starting the BBB method today. Got a 28K in ground pool with colored plaster and pebble surface. How long after adding bleach can i add MA as it is near 8.0 right now. Also, how long should i wait to test the FC and CC levels if I add the chlorine at 4:30pm. My pool usually turns off at 9pm. I am trying to stabilize the pool to add Borates next week. Thanks.
