Homebrew PCBs

My hose comes out of the tank above water level, however, I just 
coil it up and let it lay in the bucket around the tank.  Something 
must have got it going to siphon it all out, not sure what or why, 
but lesson learned!

I have one of those valves around here somewhere and am going to 
have to find it and install it.  I would much rather be safe than to 
have that kind of mess again. 

Apparently, based on the longer etch times, the brass 
fitting "consumed" a lot of the strength of the Ferric Chloride as 
it melted away into never-never-land :-( I guess I will have to 
order up some more powder and make a new batch soon.
