Ummmm ....Current is not expressed in milli volts?

Ah, good. I'll forget the AC then. I recently used the electrophoresis
power supplies to make a couple of gallons, and they came out somewhere
between 25-30 ppm, and very clear. I limited their current to around 50
mV. Found that switching polarity is really necessary because otherwise
the negative electrode just collects the silver from the positive, and
grows long beards with it, while the other one covers itself with, I
guess, silver oxide and releases less silver into the water. It was
stalled around 18 ppm until I started switching polarity, then it picked
right up.
I also made a third batch, but let it get away from me, up over 100 mV,
and it turned dark and muddy. It wasn't a clear brown, but a muddy
brown. not sure why. Anyhow, I thought this might be good to test the
H2O2 on, so I put in a 1/4 tsp after it sat there for a day. It turned a
bilious green color. Ew. It is so uglyl that I'm afraid to use it for
anything, even the hot tub.
Automatic equipment is next on the agenda. I need to be able to turn it
on and leave it until it is done.
Cheers!
