Very simple question. What is a refugium? I have seen it mentioned many times in this forum.

Diamond,
To put it about as simple as I can, it is an additional tank which contains macro-algae and the main tank's water is run to it to remove nitrates.

I just asked what's the best type of water pump to set one up. I am planning to add one to my system because of it's non-mechanical filtration, plus I can feed my fish the algae as it grows.

Diamond,
According to Chris

[hr]
, here is the definition "A refugium is a body of water that's physically separated from the main aquarium, but shares a common water supply with it. (One) purpose of a refugium is to provide a refuge for animals and(/or) algae that suffer from excess predation in the main display tank. The (net) effect is to increase the diversity of the whole system beyond that possible with a single tank of similar size."
Again, a lot of people use it to help keep down nitrates. I hope this helps.
