Green Birdsnest and Green Porcillipora Color and Care Question

[stl.reefer]

I've been running an SPS dominant setup for the past year or so and lately have been having problems with coloration and polyp extension from my green birdsnest and one of green porcillipora's. Both appear to be bleaching and the birdsnest especially looks like its dying. I have a red montipora, rainbow porcillipora, a different kind of green porcillipora, pink milli, red digitata, multiple acro's, meteor shower and hollywood stunner chalice and they are all doing good, displaying bright colors and good polyp extension.

I did a water test today and the results are as follows:

-Temperature: 78 Degrees
-Salinity: 1.025
-pH: 8.31
-0 Ammonia, Nitrate, Nitrate
-Phosphates undetectable
-Alkalinity: 9.5
-Calcium: 460
-Magnesium: ~1400
-Iodine: 0.06
-Potassium: 390
-Iron: 0-0.05

Take a look at the pictures.

Any help or tips would be greatly appreciated!

Hi mate, can i ask what and how much food etc goes into the tank each day and how you manage your nutrient export to keep zero phos and nitrates.
Have you changed anything in the last month or so regarding lighting and or your water keeping methods.

I feed Docs Eco Brew and Eggs, Flakes and PE Mysis. I dose B-ionic 2 part: Calcium and Alk. daily, along with red sea reef energy A and B. I run a 6 bulb dimmable ati t5 sunpower. Reef octopus skimmer and 2 phosban reactors, 1 with carbon and the other with GFO.

I have not changed anything over the last couple of months.

Take the carbon and gfo reactors off-line if you have zero phos n nitrates.
