Thanks guys!!!! I was lookin around for glass today and came across a cracked 150 for $75, I think I found my viewing window! and maybe some extra windows for fun. I really want to make this tank unique. I have been doodling in sketchup, but so far no permanent plans yet. Once i get the tank and see how bad the crack is i'll know if i am going to repair the tank and set it up or if i will use the glass for my project tank. guess it kindof depends on which pane is busted up.
