I bought some ph minus from the pool store, and it's sodium bisulfate. Do you think I should use it, or buy muriatic acid from Lowe's instead?

My concerns with dry acid are adding sulfates to the water. My concerns with muriatic acid is safe handling and storage, strong fumes can make me dizzy.

Ph 7.8 I need 12oz to bring it down to 7.5
TA 110
CH 190
CYA 35
FC 8.0, CC 0, TC 8.0 just finished SLAM process
Temp 82* F

Bringing the ph down to 7.5 should give me close to 0 CSI if nothing else changes.
 
Sulfates will be a long term issue.

I keep muriatic acid at arms length and tip it down at the coping level to pour it directly into the pool. My nose gets no where near the bottle.
