Eheim Compact On 2100

The Eheim CompactON 2100 is a powerful yet compact aquarium pump, delivering an adjustable flow between 1,400–2,100 L/hour while consuming just 38 W. Thanks to its ceramic bearings, it runs silently and reliably, making it ideal for both freshwater and marine tanks. It can be used submerged or externally and comes with a suction-basket, strong suction-cups, and threaded hose connectors for flexible installation. With a maximum head height of 2.4 m, it’s perfect for sumps, circulation systems, or return setups.
