The metal frame is going to be very important. I don't know about
thickness. Might approach that with a glass company when you figure the
force at the center of the span. Your 3 x 3 x 6 is 54 cubic feet of
water, At 62.4 pounds per cubic foot, you have 3369.6 pounds of water.
You will need to be very sure of the base for your 1.68 ton tank!

We build a 94" x 9" x 15" tank out of window glass. To prevent
breakage, we have angle bracing along the bottom and top edges (bedded
on silicone) and have 3 cross pieces of aluminum across the top to take
the weight. In effect, we have four 23" tanks side by side. The volume
is relatively low as the tank is not very wide. Your 72" side will have
a LOT of weight in the middle.
