Aluminum or Magnesium Anode Rod?

Hey Guys -

I'm looking at replacing my 12 year old Rheem 50 gallon gas water heater. I don't have any problems with it other than it getting old and a neighbors identical one recently starting to leak, so I figure it's time to replace mine.

My choices for replacement are a Bradford White with a magnesium anode rod or a State with an aluminum anode rod.

They both cost about the same and other than the anode rod, I can't find much difference between them.

I'm on city water and I think our water quality is probably very good.

Is there a reason to prefer one over the other?

Thanks!

Magnesium would be my choice - aluminum is a good choice if you have sulfer bacteria in your water which you should not.

Magnesium anodes protect the tank a little better. In so doing they may also wear out faster.

Nothing wrong with removing an aluminum anode and substituting a magnesium one, unless you get undesirable odors in the water.
