This Anode was proposed by G.P. (name depending on pond side :-)) Success varied, with anodes lasting from hours to months. Pieces of Lead Dioxide were put into a porous plastic bag/wrap. A Graphite rod was placed on top of the contents of the bag/wrap and the contents + part of the Graphite rod was plated. The bag/wrap used in the picture was mesh material used in the garden to keep down weeds.
