Why is the Corro-Protec smaller than the original magnesium anode rod?
Our response
Since the magnesium anode must sacrifice itself to protect the hot water tank, it is important that the anode is large enough to last for several years.
However, since the Corro-Protec anode relies on current to protect the tank instead of sacrificing itself, the rod can be much smaller.
