All Suburban water heaters come stock with a magnesium rod. You would only want an aluminum rod, if the water in your area depletes the magnesium rod too quick. However, you wouldn't just use an aluminum rod if this wasn't the case, or the protection that the anode rod provides may not be there.
Suburban provided our forums with a series of instructional videos for their water heaters, that we keep in the FAQ section. You can find them at this link:

Video 1 there explains the function of the anode rod and when you would select an aluminum one over the magnesium.
I am copying it over here to this thread, but would suggest to others to view all 5 of the videos at the link above to gain a good working knowledge of these heaters:
