hello, i just bought 150G gallons tank with bottom pre-drilled 2 on 1 side and 1 on the other side. however, it is in the middle of the tank not in the corner left or close to the back glass for me to put the weir. i want to get a use out of it (possible sump). what is the suggestion? from what i know, i can't just make that as a drain line because when the power went out. my house will become a aquarium.
P/s: the picture is the one with drill hole like mine from the internet.
