What's Wrong with my Firework Cloves?

[DocRose]

Any idea what’s going on with my Firework Cloves? They’ve been doing this for about a week now. Staying retreated during the day and MAYBE extending during lights out. It’s not the intensity because they’ve been in they spot for two months with no issues. My acan and zoas are still opening up.

Water parameters are:
Salinity - 1.025
Temp - 78.8-79.2
dKH - 9.2
PO4 - 0.09ppm
NO3 - Couldn’t get a reading this morning. User error.

Note: Picture was taken during feeding so that’s what the particles in the water are. And yes I’m aware of the cyano. Tank is only four months old so it’s still balancing out.

Looks like cyano irritating the corals. Keep blowing it off.

Didn’t know it could do that. I’ll be sure to blow off daily.

I have mine mid way up in decent flow and they open like crazy. Sometimes they will close up like that but tend to open back up after a bit. If it's a newer frag it takes a little for them to settle. Also if your tank isn't done fluctuating in your cycle it'll bother the corals.
