The Current USA Fission Nano-Skimmer is the smallest protein skimmer in the world, measuring only 6.5” high and 2” in diameter. Powered by an efficient air injection pump, the patented design rips bubbles into a vortex foam froth, breaking apart proteins and organics, removing them from the tank. Easy-to-install.
Features:
The air injection submersible pump pushes 84 gallons per hour through the skimmer, mixing bubbles and organics in a tornado fashion. The collection cup easily lifts off for easy cleaning. The pump can be connected so it is next to, beside, or under the skimmer.
The unique submersible design fits into almost any nano reef, nano cube, nano-style aquarium system (6.5" H x 2" Dia.). Will fit the JBJ Nano Cube.
Includes a submersible venturi pump, protein skimmer, suction cups for mounting, hanging kit and two connection elbows.
The Fission Nano-Skimmer is a perfect addition to any Current USA Aquapod or other nano-reef tank that can accommodate a power cord over the side of the tank and a 6.5" X 2" protein skimmer.
