I have an older 135 gal tankmade by oceanic and its made of 1/2 in glass. I was wondering is a normal thickness for 135, seems a little bit thick to me. I have heard in older tanks they made the glass thicker, so I was wondering what they make 135 out of now? By the way I love the tank its really heavily built, with my best guess it is maybe anywhere from 15-20 years old and the silicon is still in preaty good shape. I will probaly have to redo it sometime though, don't want it leaking!
