I've been looking at this paper by Wojtowicz where he calculates the amount of chemical addition needed to adjust the pH, taking into account the total alkalinity and cyanuric acid (at least that's what I think he means by "CA").
Unfortunately his graphs for increasing the pH are targeted to reach 7.8 instead of, say, 7.2 or 7.4. As someone who likes to "get close enough to the answer" without putzing around doing acid demand tests or the continuous "add this much, retest, then do it again" cycle, I would think a full set of curves that are targeted to typical pool conditions would be very useful. I know that there is a lot going on in the water and that it is complex, in fact that's something I keep trying to drill into the minds of people I work with. And then there's the typical consumer who needs directions that just say "add X" even if they have to repeat it often.
Anyway, my point is that I'm surprised that I haven't seen such a set of curves anywhere else including here. Am I just not looking under the right rock, or do other people enjoy the added tedium of hyperbolically approaching the target?
