The typical instructions for raising or lowering pH say to add X amount, then retest later. I assume that is so that you don't over-adjust or end up "see-sawing". (That said, I have never overcorrected, it always seems like the doses are about half as much as they should be.)
Outside of the over-adjustment / under-adjustment issue, and possible cloudiness if you bump the pH up too quickly, is there some other reason to make smaller adjustments, such as creating toxic gasses?
