I'm also using two "small bubble" makers on a dual outlet pump, but
haven't had a chance to get much tank use yet. They're the kind with
the "fuzzy" looking textured surface. They did put off a nice strong
mist of bubble fizz, which was spread evenly across a vertically
hanging double sided board, so I think they'll do OK. It was strong
enough that if they were too close to the surface, it would produce an
airborne mist (eventually I'll mount them to the base).

I looked at a standard tube with holes first, but chose these. I
wonder if you could just drill up a tube for it. I thought about
making a plexi rectangle with some type of standoffs to create a
vented chamber in the bottom of the tank, and gluing my tubes through
the tank's sides near the bottom, but figured it might be a hassle
while filling the tank and waiting for the etchant to fill the chamber
(or having the air try to lift it out).

The bubblers seem like a good area for DIY. With economy heaters and
pumps, they were almost as expensive as some of the important stuff.
