Sulfuric or Muriatic acid to control PH?

Muriatic acid.
sulfuric acid will add sulfates to your pool. As they build up the destroy metals and concrete/plaster.
 
For some reason, pool stores in Florida push sulfuric acid.

I don't know of anywhere else where the stores push sulfuric.

I would imagine that there's a really good sulfuric acid salesman who covers Florida.
