That is a very nice little electrolysis tank. Now that you have it up to 10 amps you will be able to see more progress faster. As the amperage goes down that indicates the buildup on the rebar. The ground nuts you have are excellent choices because it will provide a sturdy connection. Yes, it will take you a couple minutes more than say simple battery cables -- Rudi's Electrolysis Tank
. but the main advantage in your method is the connection. Like all good circuits you need good connections and you have em. Be Happy
with what you have as it is really cool
The only shortcoming I see in your tank is capacity. You may decide that you like electrolysis as a great way to clean a lot of stuff -- up to and including torque tubes, finals, hoods (yes .. hoods), implements and all kinds of things.
I have 3 sizes of electrolysis tanks. A 45 Imp Gallon, a 5 Imp Gallon (20 liters) and my 440 Imp Gallon/1600 Liter tank. My take on the 20 Liter tank was to use a metal basket as I want it to clean up small metal parts and nuts/bolts/washers etc.
As far as the science behind electrolysis, I find it to be interesting and a worthwhile read, but in working with it, all that stuff is simply a distraction/side show. Electrolysis is a simple and effective both in a time/cost/energy expenditure as well as ease of the process. Much cheaper than media blasting and much cheaper and easier than wire brushing as a primary means to remove all that gunk.
