Same problem, I tried heavy duty epoxy.  Never worked.  You
must have that brace, though, or you'll eventually be sorry.

Silicone is not a good thing for that, though, because it doesn't
resist constant pressure.  My epoxy didn't work either, so I can't
fault you for that.  ;-))

After many attempts, I finally found a solution with which I was
actually happy:  You can get two of those "U"-shaped cable
clamps from the hardware store big enough to invert over the
front and back sides of the tank ($2 each).  Then, run a small
chain ($1) between the two.  Super strong, great support, takes
up no extra space, no cutting/glueing/curing, and even looks nice.
