Overflow Lid for 2,400GPH box.

AO Overflows can help turn your reef aquarium into a high performance aquatic environment that will make your coral (particularly your SPS) thrive. Highly effective, the overflow box increases the rate at which surface water is pulled into the filter, reduces surface film and dust by removing water from the area of the aquarium where most organic waste is found.

Whether you need to skim water for your sump, your closed head circulation, or external fed powerheads, you should use an overflow box to help protect your inhabitants and provide control over the amount of water leaving your tank.
