Maybe I missed it in another post somewhere, but what do have for biological filtration? Your bacteria that you'll establish when you cycle need a place to live, and without substrate or live rock, they won't have that. They don't live primarily in the water.
Most folks cycle with their live rock and sand in place, so that the bacteria will take up residence there. Otherwise, you'll need some type of wet/dry filter, or a biowheel, or something like that.
