I am sorry...I have not thought about using the BBB method, maybe because I do not even know the old school method. Right now the pool is crystal blue and clear (probably not for long with these numbers). It just had a recent water change and chlorine wash maybe a month ago. Sand filter (new) and pool pump (new). It is about 35,000-40,000 gal diving pool with pebble tec finish and attached spa.
Is the BBB method okay with this type of finish? And silly me I just bought 25 lbs of chlorine since I new the Chlorine has not been stabilized since the water change (per pool man that is no longer with us)..
Thanks for your help!!
