broken bottom brace on bowfront corner tank

[wolfear]

Having difficulty finding a definitive answer on this. I've got a corner aquarium, Juwel trigon 190L (50 US gal) bowfront type. Recently I did a water test, barely filled it a third of the way before it failed. Providing that the trim wasn't too difficult to remove, decided to take it apart and reseal everything---it was definitely leaking the most from the bottom----Silicone was really uneven everywhere, super thick in places and super thin in others. Anyway, the top frame/braces are fine, the bottom frame is broken. I was considering just leaving the bottom trim off and supporting it like I do with my other rimless tanks, with a thick high density foam mat. But I'm unfamiliar with the structural integrity of a corner aquarium like this, can can't find an answer if this will be enough to support the bottom, or if it needs additional bracing.

I serviced tanks for a lfs. In the 6 years or so that I did that, I only saw 1 tank fail and it was a bowfront. I would be afraid with water pushing on the front glass that it could fail. Its pretty catastrophic if it does fail!
