> Have you calculated how much acid it would take to change the pH of a
typical hive significantly and compared that amount to what is actually
employed in various acid treatments, and this one in particular?

A good question.
It reminds me of another aspect of pH associated with varroa control. Here
in Europe, it is claimed that the pH of oxalic acid must be equal to one to
be effective. A higher pH would not be effective, a lower would even be
harmful to the bees. Is this parameter also taken in account in the States?
