No room for a quality protein skimmer? Think again. The Eshopps Nano Skimmer has a small footprint of just 4 1/2" x 2 1/4" x 11 1/2" high that allows convenient placement in small spaces- perfect all-in-one nano aquarium systems. Easy-to-install in-sump skimmer is powered by the energy-efficient 6W Italian-made Sicce Micra venturi pump with needle-wheel impeller. A flurry of waste-removing bubbles is generated to help maintain cleaner, clearer saltwater aquariums.
