Deluxe CS50 Overflow with Lid and Air Pump

A built-in overflow is the most efficient method of draining aquarium water to a sump filtration system. If your aquarium does not have built-in overflow, a hang-on model-- such as the CPR Continuous Siphon (CS) Overflow-- is the best means for getting water from your aquarium to your sump without expensive modifications to the tank.

These CPR CS overflow boxes include an air pump to ensure continuous operation, even restarting in the event of a power outage. They quietly skim up to six times more water than units with tubes, and the Deluxe Models include standpipes, a venturi powerhead, and an acrylic lid for even quieter operation.
