I have 120 in wall. Very difficult to maintain and negotiate coral placement from the back and also requires lots of patience when doing any sort of aquascaping, feeding fish or pest removal as you constantly have to run back around the wall to check stuff then go back around and guess and then check again. Not like placing something and then just bending down to look. Everything seemingly requires more footwork when its in wall. It does give a crisp clean look but most of the functionality of a traditionally placed aquarium and stand is lost due to the wall being blocked. Hope this helps.
