Little rusty. Need some help with numbers

[lindz18]

First set of numbers:

FC :0
Ta: 30
PH: 7.2
CYA: 0

Do I need to get my CYA up to 50 before I even attempt to put chlorine in? Since I won't know my slam number?

Bring it up to 30 for CYA. You will want to bump your TA up to 80 with baking soda and start the SLAM based off of a CYA of 30.

So is it ok to just go ahead and start slamming with the numbers for 30?

Thanks for responding.
