Just heard from concept aquarium who is building my 96x30x24 tank. All glass is cut and ready to assemble and they want to know if I want it drilled and a overflow. I have zero experiance in sumps and no idea what to tell them need to let them no asap. I figure even drill put a valve and a cap then can not be limited later. It is going in a corner of living room so must look good. Can I get away with back left corner only on 8 foot tank or does it need center or both corners. Also what size. Fml I should have thought of this a month ago when I paid for the tank
