I'm new to this forum. I have a salt water pool and had my pool water tested today at a hardware store that sells pool supplies. The resulting print out said I needed to add one quart of Sodium Hypochlorite. A sales clerk couldn't find Sodium Hypochlorite and sold me a quart of Muriatic Acid instead. He said it was the same thing and would produce the same results. I'm no chemist, but I'm rather doubtful of his advise. Can anyone give me correct directions before I add the Muriatic Acid to my pool?
