planning stage of a 30 gallon tank.

will be my first foray into Saltwater tanks :)

i plan on starting with a FOWL tank and transitioning to a reef tank.

i have been looking a the kessil a160we lights and wondering if i could use just one on the tank.

some of my questions are... if i can use it... how high do i need to mount it? and what are the coral limitations of it?
