What's a refugium? I've seen them mentioned plenty but don't quite understand what it is nor what its for.
 
A refugium is an isolated area(usually under the tank) where you put things like macro-algae and clams to furthur break down ammonia. nitrates, and phoshpates. It's a "refuge" for these animals to hide in so they aren't harrassed by other tankmates.
