Alright im sick of my old 125g tank. So its time to upgrade tanks. I think Im going to go with a 96/30/25 with starfire front and sides. I dont want a standard overflow box and glass cages dosent do external overflows so I am thinking about having a overflow the whole length of the tank so I dont have anything protruding into the tank, but I want to leave as much room as possible. How wide do you guys think that the overflow should be?
