New Acro Help

[Chef Tommy]

Bought this acro 2 months ago. He has gotten larger but I do not notice many polyps & there is discoloration. It was pure white when I placed it into tank.

My tank is Fusion 10

Aqua Prime HD
Stock return
Hydor 240
In Tank basket with floss, seachem matrix bio, & chemipure blue

Also have a nanoskim wood stone skimmer

Ca around 430
Temp 78
Salinity 33
Alk 12
Ph 8.2
Mg seems high 1550-1600

All other coral appear fine & my 2 new monti frags are growing well.

Any advice is much help and possible ID.

Thanks!

Unfortunately that piece is gone

No polyps at all and is bleached, the color you see is algae growing over the coral skeleton.
