I was wondering about clear ammonia (ammonium hydroxide ) to
raise PH, but I have no idea if it is compatable with the process.
Even better would be a buffer solution mixed with the dye when it
was packaged.
I don't think I care too much since I'm just getting started.
I do wonder how much putting a couple of hundred watts into 4 gals of
electrolyte for 90mins will raise the temp.
Just in case I got out an old water chiller I have meant for a medical laser.
It can run down to 4C. I found a Titanium coil made out of 12' of
8mm tubing on Ebay from some guy in Riga Latvia for only 40 bucks.
(should cost $300-$600, but I've always heard Ti is cheap and plentiful
in the former soviet union.)
I'll pump 4C water through that and see what sort of cooling I can get.
If it can keep up with the heat input then I might rig up either a 3 way solenoid
or 2x 2 way to shunt the flow past the coil or force it through and drive that with
a Ranco temp controller to get thermostat controlled cooling.
I've used the same chiller to water cool a CCD camera dissapating 40W
to a constant 4C hopefully it can do even more. If it can't overcome the input
I'll just run it open loop to delay the inevitable.
Check out the Ranco controller
It's what hobby plating tanks crave.

These are pretty cool for the price.
I've got that engineer disease that makes me want to resort to massive
overkill, this is combined with a love for anything colorful or shiny.
Somebody kill me.
