So these are my final pics of the 12g nano cube, it will be upgraded this week to the new Sleek NanoCube DELUXE w/twice the lighting and better Everything else. Here you go, final layout before total overhaul.
The tank is a 12g Nanocube by JBJ, standard no modifications. The back has a filter section, but mine is just filled w/live rock rubble. In SW filtration is overrated, as live rock is the best EVER chemical filter, and mechanical is not as necessary, with so much chemical working on. I do daily top offs w/ water from the refrigirater, which is filtered by an inline filter (for drinking water) and weekly water changes w/store bought saltwater (mixed by them). That is it
For tank setup you can go to www.jbjlighting.com and click on Nanocube, then if you want to see the one I am getting this week, the DX (Deluxe) to replace this one, it's a diff. tab there.
