Does it matter which brand?

Pool store (pinch a penny) sells muriatic acid for swimming pool label says distributed by allied universal corparation... its stored in A/C indoors

Home Depot sell Smart pool muriatic acid and is stored out in the garden area in the heat (south florida heat)

Lowes sells "Crown" muriatic acid in the paint area in A/C indoors and they also sell "Smart" in the garden area in the heat again....

so my question is does the heat really deterioration of this on the bottle is says store in cool dry area?

all within $.25 a gallon
