Thanks for the input, makes sense. I didn’t want to post links but photos are on that site. I can’t imagine I’ll be buying anything over 40 gallons without some sort of brace or perimeter after my current tank goes no matter what it’s built from. Nano sure but not larger.See those fractional dims? That's probably because they are cutting it out of one sheet instead of going into a second. Sheets of this thickness are called block acrylic and usually come in net size of 48x96. Again, I don't know for sure. That's not a bad price BTW.
