alright,

i have a few corals that are doing some different things in my tank, mostly turning brown or white...

i have 2 250w mh's that i run for about 8 hrs a day. other than that, i just have the blue leds on.

i have a big brain coral that is turning white on one side. i think he was brown at first but i cant remember. its an open brain, with green centers... hes pretty up high in the tank, a lil past halfway.

i have a smaller maze brain thats real tall in the tank. he was real green before but now hes turning brown. spots of brown all over him..

i also have a green akro looking thing that looks like the tips may be turning brown...

i dose fiji gold calc supp twice a week.

im getting real good growth on my live rock(most started off white-now its purple/green) and my mushroom, bubble coral, etc etc all look great.

is this over/under exposure to the lighting? should i move the brains lower?
