how far away from my light should my frag rack be?

[amatta1989]

I have a Coralife 130 watt light (dual 65watt 50/50). I noticed that my star polyps color was starting to fade a little bit so i took them off the rack and put them on some of the rock and their color was back 100% the next day. also on my rack is a couple Zoa's and a Montipora frag.

Is there a certain distance they should be away from the light? right now my rack is about 6-7 inches below the top of the tank. is this still too close for zoa's?

Any help/opinions would be great
thanks, Alex

it really depends on the coral. SPS higher, lower light LPS/softies lower. place them according to their reactions. Its usually like 12-20+" away from the lights. There is no determined height really.
