Zinc anodes simply do not work in fresh water. Their voltage potential is not high enough.
In fresh water a zinc anode very quickly develops a coating of zinc hydroxide and sometimes a calcareous coating, both of which insulate the anode and prevent any current flow, thereby rendering them useless. This is all well established scientific fact ..... Google it.
