The app is telling me to add 2g of pH Down / Dry Acid. But I believe it should be 20g instead.

You need to put your TA in to have an accurate pH adjustment.
Like above, the TA needs to be there.
But beware your SWG does not like the use of dry acid.

Oh, I failed to mention, this is for my bromine sanitized spa. Is dry acid ok then?
I do strictly use muriatic in my pool anyways.

The sulfates in the dry acid will accumulate in the spa water until you dump it.
It is not good for the SWG or concrete but hard to say if it will get to damaging levels in 6 months.
