Problems with caulastrea/trachyphyllia

[Marc W]

Hello Reefers.

I’m having some problems that I can’t understand with the above corals.

Info:
650G peninsula

Alk 8.4dkh (hanna) VERY stable
Cal 430ppm (Salifert)
Mag 1380ppm (Salifert)
PO4 - 0,03 (hanna)
No3 - 5(raised from 0.5 over the last 2 weeks)(Salifert)
Temp 24.8-25.6° Celsius
PH low 7.9
PH high 8.1
G3 pro AB+ whitecorals schedule
PAR at corals 80-100

Feeding: 12 cubes of mysis/Artemis/krill a day + some polyplab reef roids

Latest triton test: all but green lights in all parameters(1 month ago, new on the way)

Mates:
1 Achilles
1 sailfin
6 yellow tangs
4 blue tangs
1 filefish
2 chromis
2 clownfish

Status of SPS: growing like crazy
Status of softies: growing medium/slowly
Status of hammer and torch: growing like crazy

Now I don’t understand it, the caulastrea as you can see looks “dry” no polyp extension, the trachys I had to move to hospital tank because they are to expensive too loose(happy in hospital)

What am I missing? There are no signs of pest [emoji849]
