Hopefully your uarus can find some shelter around in there... I might try to get a taller stack of rocks or another piece of driftwood for them to go under to avoid the bright light, otherwise they might go nuts.
Another thing: here's my biggest problem with going straight 6700k. Although they are the best for growth (next to 6500k, but there's almost no difference), they tend to give the tank a yellowish look, like the spectrum's failing or something. Your driftwood is going to add a little yellowish tinge to the water to begin with, which will look cool, but 6700 k's might put it a little over the top, in my book anyway. Yellow, IMO, is very easy to over-do. Its a natural look, but it can look nasty when its too much. All depends on what you like though. Tanks shapin up! post pics w/ fish when you get them!
