THe light is a basic white led lights probably 4200k or so. It will prob keep softies like zoas and GSP; however, i've seen one of these tanks with JBJ stunner strips (one white and one blue) and it makes the tank look 10x better plus they're a little more in tune with coral needs.
I am thinking more of a 10k/royal blue mix for DIY fixture either with a heat sink made myself or a par38 style bulb. Not sure yet.
The water level in this tank is somewhat interesting; displays have the back and front chambers all filled up to same level which is kind of counter-intuitive for an overflow setup. but you can raise the display water level by glueing in a wall to raise the effective overflow point. i've seen it on the display at fish gallery.
