My war coral has been slowly losing color, I've tried putting it in different heights of my tank, and most recently it was on my sandbed and didn't see much improvement.
Larger picture here.
It was under 160w of 460nm LEDs with 90 degree lenses. Today I moved it to my 20 gallon which is lit by a D120, blues are set to 100% and whites are at around 15%. The picture I took is in that tank under whites only.
The tank it was in has an alk about 12dKH, calc 420ppm, mag 1350ppm.
