We just moved from Austin to Kerrville, so I need to futz with things a while with this new water. In Austin, the water comes out of the tap at pH 10.0 but settles back to about 7.6 as it takes on CO2 from the atmosphere. A moderate CO2 bubble rate (one bubble/second/40 gallons) easily gets it to about 6.8. The Kerrville water stays above the chart (over pH 8.0) even with an aggressive CO2 bubble rate. If pH is the factor affecting BBA, then local water does have an effect. If it's total concentration of CO2, then maybe not, but I like my fish too. Seems like a lot of work to kill something that's easily avoided to begin with.
Also, your advice will be more helpful if you assume that the average planted tank keeper has only one show tank. No grow-out, breeding, or holding tanks, and no other science-guy equipment. Just one show tank where everything has to happen. Oh, and minimal futzing with the tank, like once a week with as little water changing as possible. But it has to look good.
