Believe me. I'm quite familiar with this dilemma.

I've heard many people speak of this (relative to adjusting already
alkaline tap pH upwards), though it doesn't seem to be much problem
with frequent water changes. I just sorta bungle through the
pH<->KH<->Alkalinity relationship, as well. Anyone know of a book out
there that covers the subject well? I have a college chemistry text,
and though it contains a chapter on pH chemistry, it seems to assume
some things which lead to an imperfect understanding on my part.
Well, I may not have helped much, but at least you have a sympathizer.
