Algae or BJD?

When the lights came on this morning, I noticed brown grass type stuff behind one of the heads of the 21 tail torch.. is it algae or BJD? The head clearly looks unhappy in the video below, but a couple of ours later it was all extended as it should.. sharing if that can help identify if it is BJD in which case head doesn’t open at all or some sort of algae. Also any potential solutions to this problem?

As a side note, I am also noticing much more algae on the glass than I ever had (probably 2-3x comparing the frequency of how long before I have to clean the glass now vs in the past).. this started happening around the same time I started to get a handle on the nutrients in my system.. LC and Water changes basically

Thin brown layer.. no change in light schedule..

I will move this guy to another area with lesser flow.. any suggestions on how to clear this hair algae before it takes over my tank?

Nothing you can do, or rather should do beyond maybe manual removal.

With your nutrients numbers very much out of wack count yourself lucky it isn't much worse.

Consider that spin brush for removal. If it's on the coral and easily removed I'd take it out and clean it gently not hitting the flesh band or polyps in a small container of tank water.

If it can't be removed the spin brush can be used under water.

Don't start trying chemical means though there are some that work. Keep your focus on slowly bringing po4 down etc. Which in your case would be the source of any hair alage outbreaks. From the video I wouldn't be concerned about hair alage.

Lastly I agree with everyone above about flow it's probably a good 40-60% to much for torch.
