No worries I was actually just confirming glass thickness.
Here's what I got for you:
First off this analysis may not be correct in actual displacement values as representing silicon seams and dynamic behavior is difficult and unnecessary.
So we start off by seeing what you had before, not intirely sure but my experience shows most of these larger tanks have 18" wide center brace with about a 1" trim around the top:
This is showing a displacement of 0.26mm and a somewhat unhealthy displacement pattern.
The goal here would be to at least match the displacement, as already stated the actual number isn't important, we just want to come close to matching it.
First lets compare to no bracing:
This shows max displacement of 2.22mm, so center brace does a lot.
Now lets try a 15mm x 4" Euro Brace, bigger than 4" and it's awkward, any smaller than 4" and the glass shop will be b*tching.
This shows 0.36mm max displacement and a healthier displacement pattern. This will be good, not much difference from the center brace.
However we'll take it one step further and place in 2 center braces 4" wide. Not ideal but better than the large one in the center.
Well look at that 0.26mm max and way better displacement pattern than the center brace alone.
I leave the choice up to you, but it's interesting to see, that center brace does a good job no wonder the manufacturers use them, cheap and effective. Just sucks for us.
