Ok, 5 hours after adding muriatic acid:

pH = 7.5
TA = 90
CH = 160
Water temp = 83F
SI ~ -0.17

I realize these will likely change but for now I should be ready to add chlorine at dusk today and CYA tomorrow morning. Still not sure I should simply use 8.25% bleach or another type of chlorine (as bleach is high pH and I don't want pH to shoot back up).

Since I am planning to use the BBB method and will adjust daily, I don't think I need that much CYA. I was going to follow the 25ppm recommended by my installer however I have no idea how much CYA to add except for Leslie's recommending 3.5 pounds for my 14K-gallon pool: should I use a different dose the first time?
