Bottom tray should have floss and carbon, next tray should have floss and sponge or carbon/zeolite mix and last tray would have sponge/tubes mix. Every tank is unique. You have to adjust for your application.What is your biological loading?

The canister filters from the bottom up, put the carbon on the bottom ....I believe the course sponge should be under the carbon in the tray. I am not sure about the rest, but I would go with media last and use floss in between..floss can be changed during monthly maintenance or perhaps replaced with a different sponge. Hope this helps.
