So guys I ran into a dilemma... For the tank I wanted to go 7' long x 3' deep but if I go 7 the tank will cover an air vent in our dining/fish room and so now I'm trying to work things out because if I put it on the other wall it will be covering a window and sort of make it awkward gap in between the stairs and the room if I do 3' deep. So I could do 6' x 3' and not cover the vent or I could do 7' x 30" and not make it awkward getting to my stairs. Or I could just do whatever I want and cover the vent or make it awkward getting to the stairs haha
