Sump support.

[blacknife]

I grabbed a tank from a buddy that i am going to set up soon.
it has a metal stand that came with it. the stand looks like a box.


the tank Am planning to use as a sump is the same length as the stand.

so it sits with no support on the long sides. what is the best way to support the long ends. i think its 3/4 inch tubing.

I would prefer to keep an airspace underneath as well.

would a sheet of pine board or plywood, either treated or painted do the job?
