Possible Electrolysis Improvement

Initially, when I first powered up the circuit, I was seeing about a 4A current draw. But this dropped off significantly as the rust particles began to build up on the anode. If you think about it, I am trying to remove rust from a relatively large surface area and collect it on an anode with a relatively small surface area. Frequent cleaning of the anode will help. But I may also consider changing to a different anode with more surface area, perhaps a flat metal bar, or something with many branches like a tv aerial.
