I never understood why the tank needed to be transparent.

  It didn't need to be, it was transparent because it was glass. They traded the formula for the glass. The company didn't manufacture transparent aluminum on the spot and give it to them.

    My question is more, why not I’m just use steel or aluminum?

      Because then you wouldn't get to see the whales. It's just a movie. :-)
