Torch coral dying?

[gavinz]

Hello all, just curious if the skeleton on my torch is supposed to look like this at night when closed up or is something wrong?

It’s not dead but receding
Stress is causing this. First thing is to elevate it as sand can irritate it. These coral have a high demand for calcium important for their skeleton.
Temp 78
Salinity 1,025
Ph - 8.1-8.3
Calcium 400-425

Flow is biggest stressor. Flow must be moderate. Too much current will cause them to recede or tear away from skeleton
They need moderate intensity lighting which they use to convert light into energy

I’ll get it out of the sand, I had it low because of it getting bleached like day 3 of having it but I lowered my lights and the color is coming back so I will move it up some, and all of those params match mine except for calc. My calc is around 500-550. Flow is also an issue of mine since I have an AIO I have 2 return pumps in the back so my flow just kind of bounces off my glass and down into my sand bed

Calcium will impact alk and ph

I find that mine grow best near a wall face. The wall keeps it from getting blasted from waves but yet still gets enough.
