Let me put my �0.02 onto this

There is a possibility to find the flexible aerator for fish tanks.
I do use one in my etching tank. it makes very small bubbles, and
has the led rod inside for keeping it at the bottom of the tank. The
only thing that you should do is to take it appart, use some
lacquer/paint to chemically insulate the led rod, assemble and glue
it together and you are on. It does not preoduce any streaks on the
pcb during etching.

Will put some pictures of this setup somwhere during next week.
