Refugium help - need info and ideas

[Twinn]

I was planning to let the tank mature and I know lots of people that have had success with mandarins in 40 gal tanks so I'm not worried about a mandarin cleaning out all the pods.

Still looking for advice on sand or no sand in a fuge area.

same question.... I made a refuge out of an aquaclear 70 and not sure what to put in it to sustain and produce pods for my mandarin....
