Elegance coral help

[Yoda3983]

Hi

Advise on elegance coral needed please.

For last few weeks it's not opening as much but appears to have gone greener almost more neon green.

Temp 25
Kh 9
Salinity 1.025
Nh3 0
No2 <.2
No3 5-10
Po4 <.3 but that could be higher as I'm trying to get rid of hair algae so might not be a true reading
Ca and mg right in the middle of ideal

It's in the same location as when it opened more.... no pest can been seen on it so I'm at a loss? Is it dying?

All advice welcome

Dying, no - unhappy yes.
Placement is very important where there is moderate to good light and moderate flow. Additionally, nitrate is a little high for their liking and salinity not to exceed 1.025. I am listing recommended parameters below. The Elegance coral obtains a great deal of its required nutrition from photosynthesis, which is facilitated by a symbiotic relationship with a marine algae zooxanthellae living within its tissue.
Additionally, the coral is capable of filter-feeding. It will capture planktonic organisms, small prey, and food particles from the water column with its tentacles. It will also benefit a lot from direct or supplemental feeding of small meaty foods. This coral will gladly accept:

• mysis shrimp
• Plankton
• krill
• brine shrimp
• vitamin-enriched brine shrimp (using selcon vitamins)

• Salinity: 1.025 – 1.026
• PHOS: 0 – 0.05 ppm
• Ammonia: 0 ppm
• Nitrate: 5 – 10 ppm
• Calcium: 420 – 450ppm
• Magnesium: 1250 – 1340ppm
• Strontium: 8 – 10 ppm
• Alk 8-10
• Temperature 77-79
