Hair algae suffocating corals

[Rohirrimus]

Hello I’m struggling with this algae like on the video

The color is brownish, same as Dinos would be but without the “air bubble”

I’m having a very hard time atm as it’s suffocating my corals.
-hammer that has been recovering is now struggling again since the bad side keep getting algae
-struggling candy cane keeps getting suffocated in it.
-gsp I clean it and 2 days later it’s covered again
-goes on top of montipora and acropora


my params:
Alk 11
Ca 460
Mg 1490
Ph 8.3
Salinity 35
No3 3-5

water changes weakly 10% with Red Sea Cora pro and rodi

Is there anything I can do ? It’s not hurting fish or fish invertebrates but it keeps suffocating coral

I have the same problem but only on my back wall. It’s suffocating the new GSP growth and can’t be cleaned as I end up damaging the bordering coral tissue.

Won’t blast off with Turkey baster, can’t scrub or scrape so what can you do ?

not much use I know , hopefully this bumps a more helpful reply for you
