What’s going on with my torches?

[paschka]

Hey guys my torches are not doing well. Their polyps are not extended fully. They also close sometimes for some minutes completely. You can see them here: https://youtube.com/shorts/qpa1yAYHZbs?feature=share

I’ve got the one in the front for over a month and the one in the back for about 7 days. I did not acclimate them with my lamp because I never did that before. Everything is fine:
Salinity: 35ppt
Alk: 10
Ca: 550
Mg: 1500
No2:0
No3: 6
Po4: 0,03

my tank is a 16 gallon cube and I have a ai Prime hd Running on lowered saxby settings.

My tank is 3 months old. I mostly have lps in it but also 2 leather corals.

Maybe too much light? Try turning lights down and see if they open more. It is a simple thing to try at least. Mag is kind of high as is Ca. But I am not sure these levels would cause tissue recession.

This could be but i can’t imagine it’s too much light. My ai Prime runs on Maximum 25watt (saxby) and is 8“ above my tank. My torches are on the bottom of my tank so …
