I have a 5 gal. tank and use Ferric Chloride can etch upto 4 single
sided 8" x 12" boards in it. I have three rows of 1/2" CPVC pipe
across the bottom with I think about 1/8" holes on each side about
1" or so center to center. I use a small air compressor to get
enough air volume. A standard fish tank pump worked OK when I had
my smaller tank but had to go to the air compressor when I started
using the 5 gal. tank.
