If you posted a thread with this info I would appreciate pointing me to it.

I was looking for something that would take
pool size in gallons
% concentration of muriatic acid
and lowering PH 0.2 ppm
You can use The Pool Calculator for some approximate computations including the effect of TA, but it's only approximate. My spreadsheet here will do the precise calculations, but it's not designed for novice users. You can PM me if you decide to use it and I can walk you through some sample calculations.

I intended to finish a simpler spreadsheet (that I've already started) that Jason could use for The Pool Calculator calculations and I took some stuff to Yosemite with me, but ended up hiking Half Dome instead. Some day I'll get around to it.
