I've scoured the internet and called BRS customer service and can't find an answer. Looking to add a Medium Aquafuge2 to my 22 gallon rimless reef tank. I have 4" clearance between my tank and wall. Specs say the aquafuge2 is 4.5" wide, but I assume (and verified by BRS) that includes the hangers over the glass and in the display tank. Will someone who has one measure the width (from display tank to wall) of the Aquafuge2 tank, the portion that hangs outside the display tank and let me know if 4" clearance from the wall is sufficient. Thanks in advance! Tony
