I was considering placing the 150 gal that i am setting up perpendicular to the wall, i.e. at a right angle. The tank would jut out 5 feet from the wall. Does anyone have a tank like this? The prob is that it is a RR tanks so it has the built in over flow and bulkhead hole. Can this be removed and capped? i would use oneor more of those hang on overflows. Would this work? the tank is 24" front to back, so i think it has the room.
