tank size

[jpointer311]

I just acquired a new tank, the guy stated it was a 90g but it measures 48.5x18.5x23.5 inside dimensions are 47.5x17.5x22.5 ( I think those are right but I'm doing it off of memory so they are close) so would it be an 80g? Seems like a strange size. Also for the brace in the center it is a 18" piece of 1/2 inch glass? Any info whether this tank is a 75-80-or 90?

Based on my measurements it must have 1/2 glass... Hmm that doesn't sound right, ill check in a few minutes. If it does, is that good or bad? I know the tank is heavy as heck.
