Just a few questions regarding your new tank:
- does it have "built-in" filtration?
- if so, what? is it the 3 compartment in the back filtration? With the sponges, etc?
- Does it have built-in lighting? If so, what type of lighting? PC lighting? (compact fluorescents)
This tank will work quite well as a nano reef. Meaning that you can indeed make quite a nice reef aquarium out of it, IF you stick to some rules.
Have a look at the tanks and pictures in our Nano and Nano competition threads...
Then we can discuss this further. Please ask as many questions as you can and want.
BTW: what else do you have? Only the empty tank at the moment? Or do you have sand/substrate and live rock in already as well?
