Like Pool Math; use it all the time after I've tested pool chemistry using TF test kit. Just now it occurred to me that I may be doing something incorrect relative to pH measurement. On the line that mentions adding muriatic acid, there's several options, one of which indicates "31.45%-20 Baume", and that's the one I've been using. I haven't even a clue what Baume means, or the figures that precede that term. How do I determine if that option is the correct one? Thanks very much.
Pool Math question

Most of the muriatic acid for pool used to be around 31%, then a lot of the brands sold in big box stores changed to "safe" versions which lowered to concentration to ~15%, for the same price of course.
I think pool stores generally still have the high concentration stuff and you can find it in other sections of the hardware stores.

Thanks very much for your replies. The muriatic acid I bought at Home Depot is, indeed, 31.45%, so the option used on Pool Math is the correct one. Again, thanks for your help.
