My corals are losing color my stylos and other corals are turning brown. I thought it was phosphates but my phosphates are in order. I was looking at the manual for my black box LEDs and it says with the lights being 12” above the water surface about 6 “ inches below the water surface, the par would be 500. My stylos are there. They used to be purple. Now they are almost white. And other corals are turning brown. Could this be a light issue. All my other chemistry is perfect.
