New Algae Problem need help

[Kruss7]

Hi everyone

My tank is very stable, has been doing great for over 2 years now. Growing Acros great with good colour. No algae problems till now. I had this algae pop up and it is very hard to scrape off.

Would appreciate if someone could tell me what it is and the best plan of action.

Parameters
Phosphates 0.04
Nitrate 1ppm
Alk 8.4 dkH
Calcium 445
Mag 1553
Ph 8.2
Temp 78
Salinity 1.026

Can’t see it clearly, but in some photos, it looks like bubble algae.

Thanks for your reply.

It definitely isn't bubble algae though.

It’s this red stringy algae that is circled.

my guess would be red hair algae..
