I'm just confused as to what is causing the oxidation that Larry is referring to. Larry are you adding permanganate or something to your salt? I don't think so. Saltwater shouldn't have anything that can act as an oxidizer in it. Oxidizers are things like chlorine, iodine, and potassium permanganate.

Larry, you lost me on this one. Its not often someone can stump me on a chemistry issue but you got me here.
