Ok, so I just did my first set of tests. Pool finished filling last night.
My pH looked just a bit pinker than the max 8.2 on the block. I'd guess 8.3.
Chlorine tests were as I expected.
The CH and TA are puzzling. They seem way off. The CH test seemed fairly straight forward and don't think I screwed it up. The TA test I did as instructed and wiped the tip with a damp cloth after each drop. It says it's supposed to turn red. At drop 27 and after it would turn magenta for half a second at the top of the vortex then back to green. At drop 32 it definitely stayed magenta. I added a few more drops looking for more of a red tint but just got a deeper magenta.
I used the SpeedStir. That thing sure is handy.
