Evan knows this stuff for SWGs better than I do. I was close, of course, on most of the numbers but he KNOWS much more precisely what they should

However, I DID forget that SWG pools frequently experience rising pH so you end up adding a good bit of muriatic acid to get them back down. I thought it was just due to the out-gassing of an uncovered pool with a lot of natural aeration....my bad!
