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!

HVAC is good for 3-5 ppm, but the particles get big quite quickly above that. LVDC with plarity switching makes very good up to 20 or even 25 ppm in some cases.
