A water level gauge can be added on the side with a small clear tube.
Why? Well, you really need to see your electrolyzer -- to watch for corrosion, even on stainless steel parts, because something that is advertised as stainless may still not be stainless. And you need to see how effective the electrolyzer is, not hide that fact.
My two cents.
