thanks. I am using the stock lights (2 36w), no additional power head just the one that came with it, i am not using a protein skimmer and it really isnt needed for this small of a tank, i usually do a 12-14 day light cycle and then just turn on my lunar's at night, in the back compartments, i have sponge in the first, ceramic rings, bio balls, and carbon in the second, and just my pump in the third. i am planning on doing a refugium in the back soon though so all that will come out except the pump. i am glad to see that you have bought a nano cube because i love mine and i am pretty sure that you will to!
