Anemone Color Fading

[jp415]

All - I have an anemone tank but looks like some of the anemone color is fading on a few of them. They were bright red before and now a few of them are showing more a green / dark base on the tentacles. Would anyone be able to shed some insight on what I am missing or can be doing wrong.

Sherman / RBTA Tank.
Nitrates -50+
Phosphate - .5
PH: 7.9 - 8.1
Alk 11
Calcium 475
Mag 1420
Lights - 12 hours - 7 hours of high intensity and 5 hours of viewing
2 x XR15 pro G5
2 x Reefbrites - 90%
1 x kessil 360x - 30%

I have been feeding the discolored nems a clams with a piece of a healthy nems tentacle but it seems be losing zooxanthellae somehow. Currently my nitrates are high but am running biopellots and vodka dosing the bring them down to the 15-25 range. The par levels are 320 at the top and 100 at the bottom of the tank. The flow is low and around 20x for a slower motion for the leathers and nems.

Should I be running lower intensity on my lights? Shorten my lighting period or increase the flow.

I am running my lights on a 12 hour period with 7 hours with 5 hour cool down.

Not an anemone expert, but most of them still look really good. I might try to bring your phosphates down a bit, too.

I run a custom "radiance" schedule on my Radions (check out the first page in my build thread) @75% intensity - so you could always bring it down just a bit.
