Bleaching?

[vncvr1982]

I have only had this birds nest frag in the tank for about 3 days. I got several frags from TSA on Friday. They all look great, they all opened up within a day. Except this stylo.. it’s got a decent sized white spot that includes some or the encrusting on the plug, that area isn’t opened up but the rest of it seems happy. I have the coral about mid level, with medium/high flow. AI Prime 16 running at about 55% intensity.

1.024
PH 8.9
Cal 470
Alk 8.8
Phos .08
Nitrate 4.3

is this bleaching? Chemistry issue?

moderate light and water flow !!
How did you acclimate this coral?
Ph is getting high - Are you using RODI water ? Range should be 8.1-8.3. Yours is high in alkalinity
What test kits are you using ?

Dip it in an iodine dip and see if it helps. Its definitely not liking something in the water, the params or lights etc...
