What is the preferred way to add muriatic acid to the pool, and what are the handling/application precautions?
I'm a new pool owner, and my pH is around 7.9 - 8.0. I've added 6 lbs of pH Down (sodium bisulfate?) so far (as directed by the pool store), but the pH has barely budged if at all. I'm wondering if I should use muriatic acid instead. Just a little nervous since I've never used it before.
My pool is 25k gallons and gunite/plaster.
