I'm rather confused whether I should be using muriatic or sulfuric acid to lower pH on a regular basis. Searching the forums here seems to suggest that muriatic acid is preferred, as it doesn't introduce unnecessary sulfates into the water.
However, both local pool stores here in Jupiter FL strongly recommended sulfuric, saying that sulfuric acid will not lower the alkalinity, whereas muriatic will. This doesn't make much sense to me (don't all acids lower alkalinity?), and seems to run against the information I've found on this forum. Are they wrong, or is there something I'm missing?
PS This is my first post here, so please let me know if this is the wrong place to post the question.
