Fading corals

Ok, I have been reading forums for like 4 weeks online and need some input from my club members. Firat off, I have a 120 g display with 40 gallon sump, 2-MP40s, SWC 160 cone skimmer, 4-AI lights, NP pellets, carbon. All my params are in range and the nitrate, nitrite and phosphates are undetectable. I have reasonable fish load, 2 clams, 6 acans, 10 SPS frags. Tank has 2-3 inches larger sand in display, marco rock structure, sump full of rubble rock (all algea either died or removed since NP pellets), use Seachem reef salt, feed Fauna Marine pellets and red algea daily, rotifers every 3 nights, frozen food 2-3 times a week, oyster feast, reef chili and phyto couple times a week. I do 10 gallon water changes weekly, try to maintain stability and leave the tank alone.
SG=1.025-1.026
Ca 450-500
Mg 1290
Alk 9.6
temp 77.1-77.2
I have issues with my acans fading color. They look healthy and show good growth. Another thing is that they are always fat and have their tentacles extended all the time. The SPS are seeing a couple looking great, good extension and color whil a few others are fading and have poor extension.
I am having a hard time finding a concensus on the AI lighting periods but the consensus seems to be that they are strong lights and should be run starting low (90-50% MAX WHITE). Mine are 12" off the water and are set at max 35w, 45b, 45r. Ramp on from 6 am and ramp down at 9pm.
What the heck am I doing wrong? Is the lighting causing the fading in the LPS due to kigh intensity? Is my tank too new (4 months old started from marco rock dry)? I assume I don't need more additives since I see awesome tanks with nothing and believe if you can't test for in, don't add it. Trace elements should be adequate since I do regular water changes. Help me regain my sanity.
Thanks!!!

 

I have my lights 12" off the water surface, which is about 32" off the sand bed. From all the forums and emails I have sent and read on the other national forums and websites, the consensus is that 35-45% intensity is about as high as anyone seems to be running at this time. A lot of people are having fading and burning/bleaching with the lights. I have the intensity dialed down to the 35% max white and the frags that were bought over a week ago from JB, placed about 20" from the light, are doing great. Good extension and color. These are the cali tort and the hawkins blue echinata. THE LPS were in there with the lights at 60 or so max and may just need time to recover/adjust. The othe SPS that faded will have to see over time as well. One thing that is wierd to me is how extended the acans "tentacles", flangella or whatever they are called seem to be ALL THE TIME. I mean these guys are open and look like they would late at night during feeding in my old tank.

I feed less than I should, so I can increase that. Craig, get me some more of my wish list fish and I will buy em. I don't realy add supplements like amino acids, Zoebak or anything but do have Coralvite and Seachem amino acid stuff if needed. I do run the NP pellets in my reactor and check with the Salifert test kits. I have to believe my tank too. I have little to no nuesiance algea growth anywhere. I literally only scrape the glass out of habit. So regardless, doesn't appear to be excess nutient buildup. If it isn't the light intensity, it may just be lack of food for the little guys. Are they like baby birds always open for the worm?

Thanks everyone. Lets get the minds turning here and solve this.

 

Update all,
Fed the acans last night with a mix of fauna marin energy pellets, full spectrum pellets soaked in oyster feast and seachem reef plus with a little phyto mix. Already today they are fat, puffy and don't look "starved" with their flangelia/tentacles all out. I can see their colors better, still not brilliant though. I will keep this up for a few every other day for a while. I also lowered the light intensity to 35/45/45 for a while and will watch closely. I have a set of frags coming from WWC next week so I want to get everyone settled in before I start doing to many things different. I will keep everyone posted.
In the meantime, I am looking for some cool fish additions to the 120. Right now I have a powder blue tang, achilles tang, midas blenny, pair of black clowns, royal gamma, 6 line, leopard wrasse, yahashi goby (only seen one time, may be missing) ble/green chromis. I want a flaming prawn goby and a trio of some cool anthias, open to suggestions. Anyone with some neat, reef friendly fish, please suggest. I love feedback and input. Thanks to all who are responding and/or following along.
