Refugium

[fubr]

Anyone have a refugium? If so can u explain like everything...details and stuff?
How do you circulate the water through it? How is the plumbing set up?
What's in it?
-Thanks

It is setup exactly like a regular sump but instead of bio balls or some other kind of filter media it has macro algae or mangroves in it.
