I've got an older model Odell 55 gallon that was given to me by a friend. I've had it for quite some time, and was fianlly about to set this thing up. I started reading up on it though, and now I can't decide. I can't really find a solid answer to whether or not it has tempered glass. Basically, I just want to make sure this thing is plenty sturdy before I set it up in my living room. Anyone have any input/experience with these tanks? Thanks!
