Algea ID please

[Lenareef]

Can you guys help me id this greenish "strings"? And what do i do to make them go awsy? We tried scrubing off, and take out with the net..but next day they are back.. is it green film algea or dinos or something else?

We did the water change, uv light is on, everything als is ok (i think)..
I think maybe problem is that we have PO4 0, but it is a salifert test..so.. dont know..

Ooo, dont mind the ammonia 0.25, i think its fals reading because it is like that from the start..tank is two months old..
Thank you

Looks like green hair algae. Your initial phosphate level on 6/14 was a little high, so this algae could be feeding off of that and bringing your phosphate readings to zero. You may still be introducing phosphates/other nutrients and the algae is consuming it quickly (and growing) and leaving your readings at zero. Take a look at green hair algae on the web and you’ll see various ways to for it, including how to remove existing algae and preventing further return of it with maintenance/feeding changes.
