Thanks Watermom!

Yes no chlorine yet. I thought of adding 9 cups of undiluted bleach (the max recommended by NPC right now) but knowing my pH is high at 8.0+ and seeing the little book that came with my K2006C says bleach is high pH, I thought I might add to my high pH/low TA issue and decided to add Baking Soda to address my lowish TA of 70.

This (rainy) morning:
Ph 8.0+ (max on K2006C)
TA 90
CH 160
Water temp: 82°F
FC 0
CYA 0
(Non SWCG pool.)

Should I wait for dusk to add my 9 cups of liquid 8.25% bleach or do it during the day today? When can I and should I add diluted muriatic acid to lower pH?
