While researching for my 90 gallon setup I have read a lot of conflicting opinions on whether or not to keep a refugium. Some are down right adamantly against them. My trigger 36 sump has a section built in for one. A lot of the more recent stuff I have been reading says that there is no real benefit, most are to small for effective nutrient reduction, and they end up becoming detritus traps. I would like something as a safe haven for copepods, since I eventually want a mandarin, but that's a long way off and it seems like a waste of space just for that. What are your thoughts? If I decide not to do one what would be good in its place?
