zoa placement in tank

[The Grizz]

I am wondering the same thing about my zoa's I have them at the top of my tank about 8" or so from top of the water level. I am running 3 - 250w 14,000k Mh, 2 - 54w 10000k T5, 2 - 54w Fuji Purple, and 2 - 54w Actinic. All my light's are about 8 - 10 " above the water level. BTW tank is a 155 Bow Front.

My gorilla nipple's, green, yellow and orange and some of my blue's frag's are open where they are sittin but the red are not all open. The blue's look almost purple.

Sorry JenniferL if I jacked your thread maybe this will help both of us.
