hmm, i have the hose above etchant level as well, and thought myself
rather safe due to that. Maybe i should hang the pump up over the tank so
that the hose goes straight up....
If you wanted that siphon to get going without intervention you could
probably never recreate the effect on purpose.
Do you have the tank covered tightly? If so i could imagine changes in
temperature to start it off by pushing etchant up the tube.
