Poylps not coming out

[Willba200]

Hi all, my poylps have not come out today for some reason. I have tested my water and all seems good. This particular coral is on the sand bed . I have some cyno on my sand bed and is seems to be on the coral. Could this be the problem? Or is it just a case of some times they don't come out??

My large mushroom seems fine and everything else is good . Salinity is 0.124. I did a fairly large water change yesterday. Could this also be why they are not coming out?

The cyano could be stressing them use a turkey baster to squirt some water on them it will flush the cyano off Even waving your hand over them will work.

Have done another w/c today and they are still the same. Also placed a ph over them and nothing so far. How do I tell if the coral is dead?

Slow down on the water changes to many will stress the tank Can you post a pic of the polyps? Some times they will close for days at a time so it's hard to tell
