Recommended Spa Shock level

[Barbie]

I've lived by the TFPS rules for my pool for years and my pool is fantastic! I'm now a new spa owner. I have two questions:
1. Can I add CYA (30ppm) if Im using Bleach..or is Dichlor the recommended chem until I reach 30ppm CYA?
2. After researching shock levels I found anywhere from 5-10...what does TFP recommend?
I tried 10ppm of Bleach 36 hours ago and I still have Combined Chlorine of (.4)
I have not even used my Spa yet???
Current info:
Spa 426 gal
Temp 101
PH 7.7
TA 70 (still bringing it down)
CH 170
Using Taylor FAS-DPD

My CYA is zero..(see question #1)
Thanks in advance for any advice offered!

1. Either is fine. The goal is to just get some CYA in the water. Use what you have on-hand.

CC are not uncommon in hot tubs due to the lack of sunlight to break them down. Does your spa have any supplemental oxidizer like UV or ozone?
