What’s wrong with this JF Day Glo Favia?

[BVF]

I received this just about 15 days ago, and noticed today the center of it is turning black. Any idea what’s wrong? Everything else is doing fine.
parameters:
temp 77
salinity 1.025
pH 8.1
dKH 9
Ammonia 0
Nitrite 0
Nitrate 1
Phosphate .25
Calcium 450-480

Thanks

Also, no par meter, but under AI Hydra 32, toward the bottom and edge of the tank in fairly low flow.

Not sure if this is the key but your phosphate is high and nitrate is low.

maybe too much light but this is hard to tell from the pictures

Thanks for the reply. The tank only has 3 small fish in it now, so that may explain the low nitrates…and maybe regular use of Reef Roids explains the high phosphates. I’m hopeful the coral can recover, but I doubt I can do much to intervene…unless someone sees something really obvious.

I have nothing to add really only mostly keeping acropora, but perhaps the folks in the LPS section could help more? Good luck.

How old is the tank? Any other corals?

Yeah I only feed reef roids if my phosphate too low. I don’t really feed My LPS only wheat the fish miss gets to them and that seems to work well.

This coral needs very little light. It's one of those corals he collected at very deep depths. I used to put mine under frag racks to get good growth and color............in other words it was in shade.

I would suggest mounting it at the floor of your tank and have it aimed to face front so it is not getting any direct light. You won't pull any of the yellow out of it unless it's shaded.

I would do this first before I look at water parameters

Took a few photos of the tank today, and this favia has really started to improve, with no real intervention; just feeding and some time.
