In that case, the "Acid Buffer" isn't a buffer at all, at least
not at any pH of interest to us. Its sole function is to destroy KH.
One would never use it with the "Alkaline Buffer", because it would
be simpler just to use less of the "Alkaline Buffer".

One would expect to use it only to reduce the KH of water that
was harder than one wanted.
