I keep it in a rubbermaid container, yes, with the lid on it when not
in use.  There's a hole in it where the air tube goes through, so it's
not 100% sealed (just 99.9% :).

I use an air stone bubbler when I'm etching, as well as an aquarium
heater.  I turn both on about half an hour before etching (i.e. early
in the whole print/develop/etch process) but remove the lid at that
time.  I don't store the heater in the etchant, but I do leave the air
stone in.

I do have a vent hood over the whole works, too.
