This point _is_ rather indisputable, and is one of the "given"s of the
situation. It's the final effect on the tank that worries people where it's
not necessary - it's too easily avoided to spend much more time than to
acknowledge the possibility because

this is the most "normal" and sane position to adopt in a freshwater setup.
Certainly Mollies and other live-bearers won't mind - Rift Lakers probably
wouldn't even notice. Even "cola water" varieties experience _some_ seasonal

usually enter into such a venture with the direct intent of achieving
specific conditions. And they most often have the tools that allow them to
produce those conditions - pH meters, conductivity meters (must say, the
handiest thing I've picked up in quite a while) and the like. And they most
often approach this particular situation with the intent of large change-
I myself change too much water too frequently, in ever- varying volumetric
quantities, to spend any more time on the problem than to answer an
occasional question about it...
