Acro Bleaching??

[Oaks]

Is this Acro bleaching? I have it at the top of the rocks with good flow. Idk why this Acro isn’t happy. The first pic with the fish is when we first got the Acro about 1 week ago and the second pic is today.

Looks like the beginnings of slow tissue necrosis/STN. There is tissue loss at the bottom of the coral.

Smooth skin Acropora can be tricky, chemistry has to be spot on with little deviation.

Double check chemistry, alkalinity is probably not stable. Consider acclimating low in the tank for a week or more before putting up top.

Thanks.

I did check the KH and Alk and it is at 6.4 I bought RedSea Foundation B today to get it to 7.6-8 dkh

Be careful rasing your alkalinity too fast. 1 DKH a day is best.
