As one of the people who wrote the original "PMDD" article, I'm
wondering about wading into this one, but not yet...
I can't let _this_ bit go though!

There is _lots_ of stuff in the archive about this! The KH and
the CO2 concentration _set_ the pH. You cannot set the CO2 concentration
by adjusting the pH. Adding acid and lowering the pH just destroys KH -
after a few hours the CO2 concentration returns to what it was before
you started.
