Are you sure about that Jim?
I use KOH as a etchant for aluminum. Works like gangbusters. I would
assume methoxide would do the same.

Mike,
The answer is yes. If it is high alloy, even better. What happens is
aluminum forms
an oxide on its skin and it becomes very resistant to chemical
corrosion. The trick is to be sure
that you let it breath the inside of the tank. It needs an oxygen fix
every so often to maintain the layer.
Good luck
Jim

*Subject:* [Biofuel] Back to the topic...New BD stuff
I have managed to score a 50 - 60 gallon aluminum tank with
fittings -
perfect for a processor.
I also have a 67 gallon (looks like lucite) circular fish tank.
I know MOX does not like aluminum, and have heard BD does not like
Lucite or Lexan or whatever this.
However, BD is fine in aluminum tanks.
I am wondering if I can use the aluminum tank as a processor, being
careful when introducing the MOX - I've made BD in HDPE2 containers
plenty (even the stray plastic bottle way early on).
So, any thoughts on the aluminum as processor and the fishtank as
a wash
or settling tank?
