EVO 500 Motorized Adjustable Protein Skimmer for Marine Aquariums up to 65 gallons (250 liters). 

The EVO 500 can be mounted on the aquarium either hung on the edge of the aquarium or in the sump. Powered by the included energy-efficient DC Runner (24V, 7 watt) that serves as a venturi pump. Polished ceramic bearings and shafts ensure maximum silence and low-maintenance performance. With the supplied controller, the pump capacity and thus the foam production can be continuously adjusted. This allows the skimmer to be perfectly adjusted to the water level and your system requirements. The 3D needle wheel ensures a high air intake and an optimal bubble structure. The included Silencer ensures a virtually silent operation. A high foaming capacity is achieved through a special water flow and through a conical foam cup. With a total height of only 14.6 inches (36.5 cm), this skimmer fits into any standard furniture. Approx. 14.6"H x 5.8"W x 3.2"D.
