Unhappy SPS (New Pics Added)

For the past month some of my SPSs stared to show signs of distress.  It's started with my green tenuis, green slimmer, and now my red planet.  White strings discharged from the corals. It's doing this twice or three times per day.  The corals faded more and more in the last two weeks, less polyps extension, and some area bleached white.  I tried waters change and calibrated my tests result at The Aquarium.  I upgraded my skimmer three months ago and added a carbon reactor three weeks ago.  Tank is 65g with 25g sump.  What can I do to help my corals turn around?

What type of Carbon are you using?

also check your ph.. i was having some problems with my sps as well.. tested everything. all alk, mag, and cal were great. so i went to lfs and tested po4, trites and trates.. all 0.. it was my ph at a 7.1!! 

To answer the questions.

 I will get some pics up later.  Retrofit LET lighting with 6 ATI bulbs from reefgeek, bulbs is roughly 16 months old. 

I'm running lignite carbon from BRS with the reactor for three weeks now, prior I used unknown carbon bought from a member on the board.  I rinsed about three minutes with the lignite carbon.

Nitrates and phosphates both zero.  Good point, I will check the PH level.  

My tank is populated with fish a corals that's why I upgraded to a bigger skimmer and added a reactor.  I think a bigger skimmer and a reactor socked the corals with clearer and cleaner water.  What do you guys think?

Thanks guys,

look for the things you changed just before you saw the issues... Its possible that running more skimming and different carbon at the same time changed the water chemistry in ways that you dont test and they hated it. maybe slow the carbon and skimming down a little if thats what you changed. You washed all the equipment before putting it in your system? if not, there may have been chemicals on the plastics or in the materials that also caused some problems...

+1 to all ! My guess is lamps also as they have lost their spectrum . As Billy stated make sure to adjust your time for new lamps .

Thank you for all the inputs.  I will order new bulbs in soon.  As you can see the white strings and bleached out from the green slimmer in the first pic.  Second pic is the Tenuis also showing signs of stress and bleached out.  Third pic is a full tank shot for reference.  I bought the blue tang from quarter size and now he's around 5'.  My tank is overloaded with corals and some fish starting to outgrow my tank.

Do you have any LPS that are extending tentacles out at night and stinging them? I just had a stag start to lose a ton of tissue because it was to close to a xenia. That may be another reason.
