Need help brought Fluval reef m90

[Carlhilton]

I just brought the fluval sea m90 and I didn't no it was a filter less tank! I have had a reef tank for nearly two years with a filter so never known what to do with one that don't have a filter!

Can some please help with what I need to put in the compartments in the back?

any help would be great.

Hey congrats on the new setup. As far as keeping stuff back there I've always been a sump guy but with those new compartments and all the research I've done on em. I would think your best bet is either carbon or some small live rock rubble. You can you filter pads but be sure to swap them out and clean them or they will become nitrate breeding grounds
