How I replaced my hot water heater anode rod with a powered Corro-protec rod to get rid of rotten egg smell, plus a lot of background about where the smell comes from and how impressed current cathodic protection works. (hydrogen sulfide formation, galvanic corrosion and battery cells, sacrificial anodes, etc). Hope this helps someone else diving into this rabbit hole!
