[smallfry]

Got a 28g refuguim from friend
Just need some input on sand base and what to put in it
So I guess what I am asking is whats in yours?

I have a 4.6g HOB refugium with about 1 1/2" of sand that I robbed from the DT, a couple hand fulls of LR rubble and a grapefruit-sized ball of cheato.
What type of light are you thinking of using? I run my 'fuge lights opposite the DT lights.
