biocube nanocube any all-in-one tank

Hi!

If you leave your tank stock, without altering (glue or cut) the back sump, what do you put in the each of the 3 chambers?

1) water comes in
2) middle
3) return pump.

thank you!!!
 
1) water comes in
<hr class="bbcode_rule" />
filter floss, carbon, and/or small rubble
2) middle
<hr class="bbcode_rule" />
nano skimmer
3) return pump----leave it pump only
Or
I have an all in one
Mine is
1) water comes in through filter floss and carbon bag
2) middle has small rubble pieces
3) return pump.
No skimmer
 
I heard, in a bag, the water flow and the small amount of surface area and contact time with the media would drastically decrease the efficiency, wasting it
