well I got my 300 gallon tank apart and came up with a crazy idea about an in the wall tank. You would only see the front and the back and filteration would be in the room behind the wall. I would just be doubling the width of the tank from 2' to 4'. The front and back glass panels I have now are 8' long and 30" tall. They are 1/2" thick glass. I know 1/2" is not thick enough for a 600 gallon tank but could I use both panels to have an inch thick?
