I'm starting a 14g biocube after breaking down my 40g and below is a photo of the setup. Currently it's stock, but I'm getting a 3.24 upgrade and also I'm looking into a skimmer... (I've seen the posts and I'm looking at a aquaC or an sapphire) I also have ceramic rings in the bio chamber and a nice semi-DSB made of sand from my 40g and some black sand on top. I also squeezed in a huge chunk of Tonga that was my prize rock from the 40g.
