12 Gal Nano question

I am in the process of curing some rock for a 12 gal jbj nano. The tank came with ceramic rings, bio balls, carbon, and sponge filters. should i nix all these and just run live rock rubble in the back chambers?
 
In my nano 12 I kept the sponges in one compartment, and filled the middle one with LR rubble, with a small bag of carbon on top for easy replacement.
 
I keep a sponge filter on mine to pick up all the crap that I stir up. Carbon is nice to have too:)
 
I customized a new rear wall, ix nayed all the media, and added a 2.5g fuge, I later added a media filter which fits perfect made for an eclipse sytem ( filterpad/carbon) for water clarity purposes, I run no LR in the back.....you can find the build in the DIY section, It has ATO, Fuge, 70w MH, Tunze skimmer, Kalk doser, 2 koralia nano's and is dominant sps....everything is doing quite well as of late.........
 
I would get rid of it, even the foam. The first time you try to clean it you will see why. All the junk it catches gets stirred up all over again. When you sqeeze it a little to get it out of the chamber to rinse. At least it did for me.

I emptied the 2 chambers (left the third with only the return pump and heater). I use a cheap Zoo Med 304 mechanical filter in the first chamber. They are small and very easy to clean, I rinse out the foam about once a week when I do water changes. For a cheap little filter it collects a bunch of junk and what I like is that the junk is contained when you take it out of the tank to clean. It doesn't spill back into the tank like the foam does.

Below that in the first I run a mesh bag with carbon and Chemi pure elite. Not a full bag of Chemi pure. I only use about 1/3 at a time so it doesn't restrict flow.

Second chamber I cut the plastic off the back glass, added on a DIY fuge light running oposite the tank and have 2 more mesh bags. One with Live rock in the bottom, another with Cheato on top in the light. These also help trap particulate, so I clean them out when I trim down the cheato about once a month.

I would highly recomend the mesh bags for everything. The bags make it very easy to clean things which is nice with low water volume and tight spaces.
 
A sponge in the first chamber makes sense if you're going to clean it all the time... Otherwise if you leave all the stock sponges in a nano, you could have a serious nitrate trap and a potential looming disaster if you decide to mess with them a year down the road. I'd remove all of them aside from the pre-filter.
