I had a refugium and I am setting up another refugium for my main tank now. I use it to keep shrimp/snails in, some live rock etc. I did keep calupera in there before but I'm not so convinced it's a good thing anymore. I think I will keep sea weeds as I can find them this time around. I use the shrimp as a source of food for the main tank but I may try raising some shrimp this time around. I won't use a DSB this time around either, 1.5 to 2 inches max. I may go with some mineral mud or something but I haven't decided yet.
