Bryopsis or GHA?

[Paul24]

I took a sample and put it under a microscope to see if it was diatoms. Definitely not diatoms. I used live rock and live sand, and it's cycled. If it's bryopsis I want to nip it in the butt ASAP.

That looks more like a Turf Algae, Byropsis looks like a fern.
Sorry I have no idea clue regarding the magnified images.

Looks like I have some GHA, turf, and possible bryopsis. I'm told this is a normal ugly phase when using live sand, live maricultured and live aquacultured rock. I dosed a little phos a week ago to keep it balanced with nitrates. Stopped now of course. Do you think this is normal? Any idea if the algae in the vid is more than ugly phase?

Tank is 3 weeks old but the rock was cured/cycled for 3 week before it was put into tank. Lights only on for 2 weeks.

Using popbloom rl60 with 10% white peak, 100% blue/uv, 0% red/green/yellow. 2 hour ramp up and down. 8 hour peak. 12 hours total.
