> But if they manage to get H2 from it then the sodium, oxygen, and chlorine have to bind into something else than usual I guess.
It's the same electrolysis process used today in swimming pools to generate chlorine. The hydrogen evaporates, the chlorine ends up in the water, and the chemical reaction ends up producing the same salt it started with. You don't have to add salt[0] and the chlorine pretty quickly evaporates and breaks down in sunlight if you don't put cyanuric acid in the water to bind it.
Mostly it could be ignored, though if the chlorine level got high enough it would kill the organic things.
[0] except for losses due to other reasons than chlorine generation
