Some updates as I work on the tank...
I taped off where my tank is going to be so I could silicone without  stinking up my house or affecting my young children.
 
 
My door for getting in and out of my taped off area is the window.
 
 
The acrylic overflow... I bought the 2 pieces this afternoon glued them  together then added it to my tank. The two left bulkheads are in the  overflow the right one isn't.
 
 
A look at the full height of the chamber.
 
 
And my little helper that has to always be in the photo
