Lee,
A bit of caution may be called for here.  One such device was being made and
marketed in Pennsylvania not far from where I live.  Being in an area where
mountains of salt are redistributed on the roads each winter, I certainly was
interested in such a device.  My interest waned when I read that the PA
Attorney General was taking this manufacturer to task (and court) because his
claims were unsubstantiated.

Thinking about it later, I reasoned that if such a scheme were effective,
then every power plant in my experience which used sea water in its coolant
system would have used it.  All I can ever recall seeing were rather large
consumable anodes mounted to their intake structures.
