Employ efficient sump-style filters without expensive aquarium modifications. CPR Continuous Siphon Overflow offers a simple and effective alternative to drilling aquariums. Innovative overflow unit quietly transports aquarium water at flow rates much greater than units utilizing tubes. Slotted grates on the overflow allow a greater range of aquarium water level adjustments. Black top reduces unsightly algae growth that affects aquarium aesthetics.
CPR Continuous Siphon Overflow can be hard plumbed with standard PVC pipe. (Does not include lid.) Use of an Aqua Lifter Pump (sold separately) is necessary to prevent trapped air from the siphon. Combine with Aqua Lifter Filter, a suction-style floss debris filter, to maximize efficiency and use of the Aqua Lifter Pump.
