I have been following the BBB method ever since having a severe algae problem earlier this year. I am the primary care taker of the pool and I asked my husband to get muriatic acid so I could lower the PH. He doesn't like the sound of this stuff and wasn't thrilled about me using it. The water is also sparkling clear right now and he doesn't see why I would mess with anything. I always thought my PH was borderline high but my husband read it in the 7.8 range so I never adjusted it. After 1-2 inches of rain the other night there is no question that it is definitely high.
My PH is at 8.2 and my TA 140 right now. I have looked for quite some time on the forum but can't find anywhere that says how long after muriatic acid is added do you need to wait to swim? Considering the amount I may need to add (72 oz.) I just don't see how it would be safe for my kids to be swimming and opening their eyes in the pool period. I am concerned about hot spots. Are there no other safer alternatives to lowering PH?
