I've got a tank made of mild steel sheet metal, and I want to

I've done a bit of reading and research, and I think I should probably
use some Cadmium/Zinc solder, probably 30% or 40% Zinc. I'm not sure
exactly what flux to use on the steel, or on the aluminum.

Could you use copper tubing? In that case you can
use regular lead/tin solder. Cadmium fumes are
unhealthy to say the least, they can kill you. HTH
