I am in the process of building a tank stand out of 4 x 4's for the 30 gal
and the 20 gal long.  I'll bring those two tanks to work.  Right now they
are on one of those wrought iron stands.  The other tanks, 2 20 gals and 2
10 gals, are on wrought iron stands, but they are each sitting on a sheet of
plywood. 
I wish I didn't have to do this.  
I talked to an architect who said that it would cost me $500 just to take
measurements and another $500 for an engineer.
All of this limits my breeding stock and raising fry.  My club is having a
big auction in November.  Hopefully, the floor lasts until then.
