For vinyl 80-100 is fine.
IF the pool is green you need to get the Cl up to about 15 ppm and keep it there until it holds. test that every couple of hours

I already added the baking soda per Janet's instructions. She's never let me down yet. I only added half of what the calculator told me to, just in case. I thought the target alk was 120 because of the post rom our dear Ben on lowering alk.
