Coral with film coming off

[eliaslikesfish]

Hi all,
So I got this little rock with some zoas, and 2 other corals (that I forgot the name of as soon as i left my LFS ‍) The grassy one has opened up pretty much before i got it on the 22nd of december, but the zoas and the one closest in the video attached haven’t since the first day the zoas were open for a day or so.. I just noticed tonight that the one in the front seems to have a clear film coming off of it. Any advice/thoughts are greatly appreciated. I included my current parameters below as well.
Temp: 78F
Salinity: 1.025
Alkalinity: 8.5 dKH (used hanna tester)
pH: 8.2
Ammonia & Nitrite: 0
Nitrate: 0.20PPM (used hanna tester)
Calcium: 390PPM
Phosphate: 0.68PPM (used hanna ULR tester)
Magnesium: 1400 mg/l

Thanks,
Elías

You can blow the gunk off with a turkey baster.
*all of the closed ones seem like zoas to me and the grassy one looks like green star polyps (GSP) but I can't see the video that well on my phone

The tank look brand new, some corals have a hard to adjust to brand new tank.

The film coming off looks like it is shedding a little, corals do that sometimes.

Besides being closed, they don't look like they are melting or anything, I think they are still acclimating to your tank, I would just let them be.
