Actually, I worked out some of the "BBB Method" from operational descriptions I got from one of the BIG companies shooting gas. Ironically, though they haven't acknowledged some of the chemistry behind their process. In part, they probably DO understand what's going on, and consider it a 'trade secret'. But, with respect to carbonates in pool water, they've published data that contributed to my working out what was going on, but have nevertheless never accepted that aeration + lowered pH is the ONLY method that works.

And, I found a few years ago, that there are segments of the potable water treatment industry that fully understand the aeration + lowered pH, along with all the chemistry.

But old habits . . . and old understandings . . . die hard.
