Hey Reefers, I got this zoa coral frag with 3 polyps about a week and a half ago. The polyps never fully open and sometimes one polyp is open and the others are closed. Sometimes they are fully closed. They are like this all the time throughout the day. My tank is around 3 months old now. I also have a torch that seems to be doing very well and a gsp which is doing well too.

Parameters last weekend:
Ammonia and Nitrite: 0
Nitrate: 5
Phosphate: 0
Calcium: 420
Magnesium: 1350
Alkalinity: 8.6
Ph: 8.0
Temp: 78 F

Lights are on 10 hours a day
I have a skimmer and use filter socks
The zoa is in the mid portion of the aquarium

Any help will be appreciated

the only thing that sticks out is that the nitrate/phosphate is very low, borderline too low.

Personally, if its been 2 weeks, I would try a different position, sometimes just a slight change of light and flow can help

Lighting type and intensity? A image under white light would help identify any pest or algae that may be present.

I used the Red Sea LED 90 2 of them
Lighting is set at 60% blue and 25% white
I’m working on the nitrate and phosphate issue
