Look at graigs list, garage sales, or used material stores like ReStore (Habitat
for Humanity) for used fish tanks, pumps and tubing.
These items should be cheap and saves you time and wondering if your built tank
is sealed and is immune to the acids involved with etching.

Subject: [Homebrew_PCBs] Building an etching tank?
I'm sure this has come up before, but I'd like to build a cheap etching tank and
wanted to get some advice before I actually do it.
I was thinking of buying a good sized sheet of fairly thin acrylic from Lowes or
Home Depot, cutting it up into two big pieces for the front and back of the
tank, two tall but narrow pieces for the sides, and then gluing it all together
with some of that plastic weld stuff.
The idea is that the tank would be really narrow (maybe 0.2") so it wouldn't
take much etchant to fill it up. I was also thinking of getting one of those
"air bubble devices" (I don't know what they're actually called!) from a
petstore and gluing it to the bottom of the tank with the end of the hose sealed
off and a bunch of small holes poked in it to agitate the etchant. It might also
be possible to put a lid on the tank and putting the air intake on the bubbler
and putting it inside the tank so that the fumes aren't constantly being
expelled from the tank.
What are your thoughts?
