	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.
