Refugiums (often just called ‘Fuges’)
Refugiums (often just called ‘Fuges’) are an excellent addition to any saltwater aquarium!

Essentially refugiums are an area or separate aquarium that is a refuge from fish where macroalgae, copepods, and other micro crustaceans are free to grow without being eaten. They can be as simple as using a small area in your sump with a basic light, or adding an additional aquarium to your system with a deep aragonite sandbed, various types of macroalgae, live rock, and high-end lighting. It’s all a matter of what works best for you! They have many benefits like: providing phytoplankton and zooplankton for your corals, reduce the amount of algae in the display tank, stabilizing pH and oxygen levels, naturally lowering phosphate and nitrate levels, and using the macroalgae that overgrows to be fed to your fish.
