Hi, "Ol' Bob!" The electrode spacing was 3 inches. The volume of DW was 2 liters. Stirring was done by air bubbler. Run time was 50 hours. No "starter" added.
Additional details. I use a spaghetti storage jar for the reaction vessel. It is tall, narrow and inexpensive glass. I also use glass tubing in the vessel except for a minimal length of Tygon tubing as a coupler to the stone. The electrodes are Canadian .9999 Maples with small holes drilled through near the edge to receive hooks shaped from .999 silver wire that hang from the lip of the jar. matt
