What type of algae is this

[tactical_XJ]

So my cousins 120g tank is been running for several months now, after a good long cycle, we finally started adding fish and corals, but his rocks have started to get this hair algae, it doesn’t look like green hair algae, looks more clear I did the salifert test I did nitrates, phosphates, alk, ph, and calcium, but his tank is now growing this algae and it’s not nice to look at, he’s running 2 mars agua lights, he had the whites at 80% and blues at 100%, i turnt the whites down to 50% to see if it will help kill the algae, we have a 40g sump with cheato and a skimmer, what yo y’all think it could be.

Looks like gha to me, but you already called it out. What cleanup crew is in the tank ?
