A refugium is a separate tank or compartment in an aquarium system that is used to cultivate beneficial organisms, such as macroalgae, copepods, and other microfauna. A refugium can be set up in different ways, depending on the type of aquarium system you have. Here are some general steps to follow when setting up a refugium:
- Choose the type of refugium you want to set up: hang-on-back, in-tank, or sump-based.
- Select the appropriate size for your refugium based on the size of your main tank.
- Add substrate and media to your refugium.
- Add macroalgae to your refugium.
- Add live rock or biological media to your refugium.
- Add microfauna to your refugium.
- Install a light source for your refugium.
