"Ole Bob" recommended keeping the cathode small, and even loosely wrapping it with a gauze or something like that to isolate the debris that collect on it. He felt that that part was not active, made the CS taste bad, and just increased the total silver ppm without giving real benefit.
I think the situation with polarity switching with two silver electrodes is not quite the same, but I am not sure of the chemistry.
