Hardware: Brewpot

I have a question regarding Stainless brewpot vs. Aluminum. Currently, I am using a 30qt. enamel coated pot, but have a 24 qt. stainless also. I just came across a new(in box) turkey frying kit at an estate sale. I mainly bought it so I could have a second burner to tinker with the valve and so on. But it came with 30 qt aluminum pot--would that be wise to use, or would the aluminum tamper with cooking the grains and boiling?

I use an aluminum pot with my turkey fryer. It seems to work fine. I've never heard any logical reason not to use aluminum. I have been told to allow the pot to oxidize inside by boiling plain water in it before using it to brew, as the oxidation seals the surface. Don't know if that's true or not, but it was easy to do and makes some sense.
