A designated housing that converts the rear chamber of the Ultum Nature Systems Dual AlO aquarium into a refugium, allowing for the cultivation of Chaetomorpha and other macroalgae as an efficient form of natural nutrient export. Refugiums improve filtration and increase biodiversity in the overall system: copepods, amphipods, and other tiny organisms are given space to flourish in a safe, protected habitat. 

The device is held securely by an adjustable clamp and features a unique design that allows for the installation of the Refugium Light to support healthy growth. The allotted space is opaque and prevents light overspill into the main aquarium.
