If you're going to use it, I'd ditch the base. Without the added strength of the top (which is essentially eurobracing), the small base may stress the seams. I'd lay down some foam and put it directly on the table like most rimless need.
They asked me to move because I was blocking a fire exit.

Ya I was looking at that last night about the base. I do have a rubber mat I am going to cut to fit. I was also thinking of getting a couple pieces of glass and doing a rim around the top of the tank so fish do not jump out. Or other wise keep it open and flat and maybe try some plants that grow in water but come out also. Anybody's thought is well appreciated.
