NEED HELP. ALL MY CORALS ARE CLOSING

[Zbass]

In my 15 gallon AIO tank have mostly Acans some Zoas. A bird nest Duncan toasdstole and GSP. Light comes on at 10 ramps tell 11. At 12 when my corals are opening. They start to close and are mostly closed up for the rest of the day. They’ve been doing this for two weeks now. I keep testing, I’ve done water changes. Changed my light intensity down. Birdnest is getting about 286 par. Everyone else is well with in its par range. Temp is 78. All my elements are with in range and don’t fluctuate . Nitrates are 7. I don’t know what to do. I’ve even got carbon running right mow. What should I do?!?

Lower the light intensity some more and see. You said they're open until the light ramps up...lower the intensity.
