29 Gallon BioCube filter question

saltie

Hi all, I just got a 29 Gallon BioCube with upgraded lights and fan. My question is really about filter compartments int he back. Since the tank is used, it did not come with any filter media. I was wondering, should I buy stock filter media or do something different back there, maybe a refug?
Any ideas and photos would be a big help.
