Beginner in SPS - pocillopora looking stressed

[Katze]

Hello everyone !

I was gifted this pocillopora nearly a week ago.
Now it looks simply weird, it seems to be stressed in the center and somewhat fine around the tips. It looked fluffy for 2-3 days then this.
Livestock: 2 sailfin molly... yup, that's all
volume: 100g
age: nearly 6 months old
Light: ~150 Par
Flow: ~high

Parameters:
Salinity 1.025 (calibrated on monday)
NH3: 0
NO3: 10-15
PO4: 0.08-0.04 (measured a week ago, I have ran out of reagents so tommorrow I shall measure)
Mg, Ca, Kh must be in order since there is only the pocillo and a very nice acan (added back in february) which means no export +10% waterchange/week
-note: yes I do have cyano but it is very week since last week

-changed lights to white so you can see the details better

tank maturity may still be too new to support corals at this point. from the pictures it could be assumed you have some cyano building up.

I can't argue much regarding age though my acan is healing, which is kind of a contrast compared to what is happening to this frag. Is there anything to be done ?

what skimmer do you use? how much are you feeding? what are you using to test water?

you can also try: https://www.reef2reef.com/threads/extreme-water-clarity-and-cyano-eradication-made-easy.916381/ if it is indeed cyano.

Skimmer is bubble magus rated for 135g aquariums. I feed a pinch of Ocean nutrition formula 2 flakes the mollies really don't need much. I am using either Hanna or Salifert to do the tests, to be exact PO4-Hanna, NO3, Kh, NH3 etc. Salifert.
-I'll take a look at the recommended thread.

add some hermits to help clean up the left over food. that's likely whats feeding the cyano.

I'd love some hermit but the fish eat everything nothing remains, and so the hermit wouldn't have anything to eat would they ?
But a hermit won't help my pocillo I'm afraid.
