I need to see a pic of what pump you are talking about. I'm thinking you are talking about your return pump? If you are...you need that to return the water back to the display side of the tank.

Yes, live rock rubble and/or small pieces that will fit back there. My brother-inlaw is doing the same thing with his RSM, and I'm doing the same with my 14gal BioCube, but mine doesn't really matter because it's being plumbed with my 120 gallon.

Wait to see what others say and search google along with asking around before you make a decission. You will find in this hobby that many people have different views, and you can make a decission that fits for you based on all the info you gather.

Have fun.
