I have a refugium and it seems to work great. It has a deep sand bed and the macro algae is removing the the nutrients from the water column. wondering if others are having the same experience. Eric Borneman in his latest book (not a direct quote) say's he envisions all the marine reef tanks of the future having an attached refugium with deep sand beds and growing plant materials. They seem to be the wave of the future.
