Making colloidal copper does not increase conductivity of the water past around 3 uS, therefore you cannot pass enough current at your power supply voltage through the water to make it ever reach your current high side limit. It's current that determines the emission rates...copper is just going to be slow unless to buffer the water [contaminating the copper] It helps to use a LOT of electrode surface area [Home Depot]
Since copper can't produce "run away" current levels, I just use as much electrode as will fit in the container, spaced pretty close together, hooked directly up to the DC power supply by alligator clips with an LED soldered to one of the leads to indicate that current is flowing. I will switch leads now and then...mostly just for grins and giggles. Monitor with laser till happy..meters won't work AT ALL.
