dino or hair algae? or somethingelse

Keeping fighting with this algae and have no idea what is it

 

Unfortunately that does look more like Dino.

What is your pH?

What I did:

1. Use turkey baster to clean all the substrate and corals daily sometimes twice. Then clean mechanical filtration once it's has settled.
2. Maintain a pH of 8.2 or higher 24/7.
3. Complete black out for 4 days.
4. No water changes just top off.
5. Back off lighting photoperiod if I saw it start to become invasive again.

It's a slow process.

Check phos and nitrate levels just to make sure you do not have other issues.

 

Tnx for quick response! Yes I did it before it was gone for one week and now start back up again. How I find out it starting after lights change. So I put additional leds green red and whites< so white is have yellow shade maybe that happened. Yesturday I did take out red ones (put them in refugium). How I understaining the 455nm doesn't matter for algae? I leave them on. Will try maintain ph for 8.4 and above

 

Additional my po4 and nitrates not detectable at this point
