Anyone have an old 125 gallon 6ft tank that didn't have the center braces? I'm trying to pick one up from Craigslist and just want to make sure it's legit and not a tank that had them removed. I had a 75 with no center brace which looked real nice but a 125, that sounds crazy.

Many older tanks were built with thicker glass to compensate for the no center brace to stop bowing. Check to see if it was built without a brace or if it was removed.

I have an older 150 tank as well without the center braces. And yes...it definitely has thicker glass...and is MUCH heavier!!!

Yep the center brace is to prevent the water pressure from bowing the tank glass out. This is why thicker glass works too its stronger and the water pressure isn't enough to bow thicker glass. But manufacturers found that a brace will stop it from bowing, weigh much less, and cost them less in glass too

The glass is at least 1" in thickness

What do you think about 3/4" thick glass? That's what the seller says the glass is. Seems a little thin?

Someone here posted a "Safety Calculator". You can calculate it yourself but at 1.9cm, that should be thick enough but if you are unsure and don't want to risk anything, go up to 1" like what Duanes did. It will be very heavy though.
