Barnacles on my anode, but no erosion -- why?
I pulled the anode on my water heater -- the rod itself was perfectly intact, no erosion at all in the past year. But the rod had quite a few white barnacles. I s****ed them off easily with a knife....

Yep on aluminum. I had to replace my rod once a year. Then I bought one at a flea market. Never would wear down. Then I heard about the aluminum vs. mag deal. Made sure I bought a mag rod and stuck it in. Gone in less than a year. Bet the flea market guy has no idea what he's selling. No rod required in my present trailer, less to worry about.
