Does BBB really make since when bleach raises PH so much? I'm just saying if your using bleach your PH problem is needing to lower it. Maybe some places don't have this problem but I also have a spa with couple falls into the pool which only adds to my rising PH problem. BBM? Also maybe since my gunite pool only 9 months old the plaster still adding to problem. Adding something to raise PH when adding bleach just not something I'm thinking about.
