Pink and Purple colors not as bright

I posted this in zoanthids, but didn't get any responses so I figured I'd try here.
I've just moved all of my frags to my new frag tank and I also moved the light fixture, so it's the same frags and lights. In the frag tank all of the purple and pink palys and zoas look more brown (mostly just not as vibrant). The frags just went in yesterday and today so I'm sure the polyps actually haven't changed in color.
So does losing the pink purple color mean my lights are too close or too far?
In the previous tank the lights sat on legs on top of the tank, so maybe 5 inches above the water (no glass top) and the frag were probably 6 - 12 inches below the water. Now the light is up higher, 18 inches above the water, but the frags are just below the surface, maybe 1 - 2 inches. So the net result is that the lights are a little further away, but a whole lot less water between them. not sure what that means . Any lighting/picture experts out there? I don't think it really maters since the lights haven't changed, but I'm running 150 watt MH reeflux 12k lamps with 2 96 watt PC true actinics. The pink spectrum doesn't look much different when the actinics are on or off.
I really want to post pics this weekend, but I need to get the light right first. I can move the light closer or farther, but it's kind of a pain to do, so I'd love to know which direction to head first.

That's what i was leaning towards, it's the more time consuming one to fix. You think just reducing the photo period would work or actually moving away from the water would be better. i could also possible build a shade (window screen) for part of it and see what happens.

Always ran them from 1PM to 9PM in the display and so I kept them the same in the frag, but I just backed it down an hour to 8PM. The actinics come on at noon and off at 10PM. moon lights around the clock.
