Homebrew PCBs

I use a 5 Gallon Aquarium installed three rows of 1/2" CPVC pipe 
across the bottom and feed it from both ends with a small air 
compressor.  Don't recall the size holes I drilled into the pipe, 
maybe 1mm.  The small Aquarium pump that I had used with a smaller 
tank did not work nor did a larger Aquariium pump work very well 
with the 5 gallon tank, even tried 2 pumps together.  Had this small 
portable compressor and tried it and it worked great, just a little 
noisy.  Put a value in the line to control the amount of bubbles.

I use Ferric Chloride in my tank.  With fresh Ferric Chloride it 
will etch upto (4) 8" x 12" single sided boards in about 5 mins. 
(longer times the more the Ferric Chloride has been used) with it 
heated, use (2) Aquarium heaters to heat it, ran the temp. controls 
up all the way bypassing the normal stop, never measured the 
Temperature.
