Help for ID this algea ? Lyngbya, GHA, both ?

[JcK03]

Hi ! I know this thread was already written before, but I didn't find any same as mine ! So thanks in advance for helping!

Short description: 20gal AIO, tank run since 3 months and 24 days.
Radio xr15 G5, running 10% white the morning only and on blue channel the rest of the day total of 8 hours.
Running skimmer, bag of carbon and bio media, jebao mlw-5 wavemaker, UV 13WATT running at night only.

Inhabitants:
2 clownfish
1 six line
1midas blenny
1green clown goby
1 ruby red scooter dragonet(eating frozen)
1 cleaner shrimp,
10ish BH (blue legs)
2 turbo
3 trochus
1 conch
1 nassarius

Water chemistry:

TEMP : 26.1°C

All parameters always been pretty stable, and I have never read more than 25 NO3 and never more than 0.07 of po4. Now my no3 is 10 and my po4 is 0, and was 0 since the last 4 weeks. I'm dosing po4 from AF,1ml a day since one week and I'm target feeding my corals with reefroids once week, and my po4 still bottomed out..
(Testing no3 with salifert, and po4 with Hanna normal range and with salifert and both 0)

So I'm in doubt I'm fueling the algea by dosing po4 and feed reefroids but I'm afraid to have my po4 at 0 since a long time..
Here's pictures of the algea, (not the red cyano this one I know)

White light only:

Blue light only:

Blue and white light:

I have check in microscope and it's not Dino;

So now, I want to know what's the best to do ? For now the algae is on certain rock, and on the backwall. It's just begin to be out of control, and I want to control them before they became too much.

I think I have provided all needed information to get help, if you need more just ask it

Hi, you will get a lot more help and useful info if you post pics in white light only. Pics like those just get people annoyed bc they want to help, but it's near impossible to see anything with all the blue light.

Nice! Wayyy better, maybe a close up so they can see the filaments as well. But I'm sure someone will give you a good idea of what that is now.

Doesn't look like GHA to me, so maybe a type of turf algae, or bryopsis? Hopefully someone will chime in with good info.

I have some bryopsis on one zoa frag and it's look really different so I don't think it's bryopsis or maybe it's a mix of bryopsis and something else
