Gallagher Fencing Tip: Replace Copper Rods With Galvanized Metal Rods

I'm using copper for grounding rods and now I've got a problem with oxidation. How do I solve it?
 
The oxidation is caused by mixing metals - copper with galvanized fencing in this case. When those two metals meet, oxidation will occur.  Replace your copper rods with galvanized metal rods.  You'll insure good conductivity and maximize the power delivered by your fence's energizer.
