sweet build! i like the outside wavebox, ive been talking about doing that for about two years. i finally have the tank i want to set up and im going to be doing the exact same thing. i was curious though, how come you didnt add "teeth" to the black acrylic where the overflow is instead of leaving it wide open? also, i was wondering if you could tell me what cutting disk you used to cut the straight edges on the tank as i am planning on doing some heavy modding on my own 140g? thanks in advance and keep up the nice work. :lol:
