Dry acid will leave sulfates in your pool water. Once they build up they destroy metals, like your SWCG.
If you drain your pool at the end of each summer, you might get away with using it.

Muriatic acid also lowers pH, right? I already bought that.

 

[mknauss]

Correct. Use that.

You are correct. Muriatic acid is all you need to lower pH.
