The perfect way to add a refugium to any sumpless aquarium!

Refugiums can add a convenient and natural way to grow various types of macroalgae, which can significantly decrease dissolved wastes which might lead to algae blooms. At the same time, these small refugiums also provide a safe-haven for desirable copepods amphipods to feed and reproduce, and this can create a renewable source of food for fish and invertebrates in the display. Fiji Cube's compact refugiums create the perfect environment for cultivating algae and copepods, with a unique baffle system that provides gentle flow-through to deliver the nutrients the organisms need while avoiding excess currents. Refugiums can also be a way to safely introduce new fish or coral to the tank while giving them a place to feed and acclimate to the water conditions.


The Fiji Cube Advanced Hang On Back Refugium Box features full brace support to prevent bowing. The unique hanging bracket system provides a robust and secure mount to your aquarium for extra safety. The brace design also features test probe and dosing tube holders to make the aquarium system complete.
