So after cutting apart one of my old 75's I quickly realized that the bottom pane wouldn't work due to the old style tank (bottom sits inside instead if under the sides)
So I grabbed a piece of half inch and went over to mission glass to get it cut (my work bench is to small to cut a 3x6 piece of glass on)
I used half inch because of 3 reasons, 1. Buying new 8mm would cost more that a new 75g tank, 2. It will allow me to put the drains slightly closer together due to overkill on the thickness, 3. I had some and didn't want to wait for it to get ordered in.
