Rainbow Stylophora loosing colors

[tmulrney]

Hi. I bought a frag of this coral a month ago at a frag swap. When I bought the coral it was beautifully multicolored. I just noticed today that most of the colors have faded and the coral is basically tan. It was great polyp extent ion and looks very health but it lost it's color and I'm not sure why.
I have a 210 gal tank which is almost 2 years old. Alk 9.5, Ca 460, pH 8.4, temp 78-79, 0.01 phosphates, 0.25 nitrates and 1.025 salinity. I run GFO, GAC, and a skimmer. The coral is 3/4 of the way up the tank under Radion LEDs. All other SPS colors look great.
Any thoughts?

Oops. Forgive the misspelling. It's a Stylophora

Hi i had radions on my sps tank for 6 months and some corals looked ok but most never grew turned brown, then stn bleached. I went to 250 watt metal halide in june and all is well.so i think the leds are the factor if every thing else is fine. Look at my pictures on my post i have a 120 gallon and 2 radions were not enough i would have needed 4. My tank was dark comared to the metal halide t5 combo.

Thank you for your response! I will look at your thread. But in the mean time I will move the coral down.

I have been having a REALLY hard time coloring up SPS with my Radions.

I currently have them set @ 100% of 20K but I just don't feel its enough so I decided to add more modules to get better spread and more PAR. I will have 1 module per ft of tank so if I dont see any improvement, I will be going back to T5's or MH/VHO.

BTW: I would aim for higher phosphates of 0.04-0.06 with Hanna Checker. Phosphate levels of 0.01 with Hanna Checker is borderline starvation.
