I decided to bite the bullet and get my first nano. I have been keeping freshwater so far but am really interested in setting this up as a reef tank. I purchased an Oceanic Biocube online here:

Total cost shipped was $187.45. I have not ordered with them before so I'm crossing my fingers it arrives propmtly and safely.

Is there any modding that should be done right away? How long between setup and adding the first critter?
