Fiji Cube Hang On Refugium Box is a great option for growing beneficial algae to help with nutrient control in your tank and for harboring microfauna. The refugium box comes with a silent efficient pump and a unique baffle system. This design prevents the substrate and the inhabitants from being disturbed while providing enough flow to prevent stagnant zones. The refugium also provides an excellent environment to cultivate small organisms such as copepods and amphipods to feed invertebrates and fish in the main tank. Refugiums are also a great way to introduce new fish or coral to a tank while giving them a place to feed and acclimate to a new system.

Fiji Cube Hang On Refugium Box features full brace support to prevent bowing. The unique hang-on support system provides a robust hang-on back on your aquarium for an extra safety margin. The brace design also features a test probe and dosing tube holders to make the aquarium system complete.

The new PRO series Hang On Back Refugium Box features the new Fiji Flow 300DC Nano DC Pump which provides versatility to your refugium setup needs. The Fiji Flow Nano DC pump allows flow adjustment to control how much water flows through the refugium filtration and it also features the feed mode function to reduce aquarium stress during feeding.
