Anodic Cathodic action works using water as the electrolyte medium or perhaps it is supposed to function somehow in a glass lined tank?

The glass lining can be less than perfect, and there is no glass protecting the steel at the various threaded fittings.

Since Atwood uses an aluminum tank that acts as an anode how much metal is lost? Do they ever become porous from that action?

I believe it is a seperate layer of anodic aluminum bonded to the inside of the tank. Don't know what happens once it is gone if ever, but the places that would be effected are at the fitting connection bosses where the metal gas control and bronze relief valve are screwed in. Also where the drain plug and the water in and out connections screw in if plastic adapters and nylon or plastic drain plug are not used.
