An aquarium overflow system for use with an aquarium tank to drain water from the tank to a sump system comprises an overflow box, a through-the-wall attachment mechanism for attaching the overflow box to the inside of a wall of the tank, an adapter for connecting the attachment mechanism to a conduit that hydraulically connects to the sump system and a baffle system inside the overflow box for reducing noise and ensuring consistent flow. In a preferred embodiment, the attachment mechanism comprises a bulkhead adapter having an insert portion extending through the wall of the tank, a bulkhead cap and gasket pressing against the outer surface of the wall and a bulkhead nut pressing the back wall of the overflow box, with a gasket therebetween, against the inside surface of the tank wall. An adjustable vent tube in the conduit adapter further reduces the noise associated with the overflow system.
