You can check out nano-reef.com you will be able to get a lot of info on nano reef keeping, and can also see what a lot of other people have done with their Bio Cubes specifically for more ideas.

when I moved my biocube into my other house I had some GSP growing on the back wall. with no water and -10 weather for around two hours it still came back strong as ever. If you are not comfortable with the lights you can upgrade. But after doing so im not convinced it made a diffrence, and Im still trying to get the company to send me the right working parts. but I have pretty much the same stuff as everyone else.
