Algae Growth on my Monti?

If you have algae growing in your montipora it means: you montipora is dead!
Or you do not have enough flow!
Algae do not grow on sps tissue!

See NOT dead!! [emoji2]
 
The fixture you have has the dim feature if I remember correctly. What percentage is the red running at? As you know algae needs nutrients and light, your tank looks other wise very healthy, you may just have to fine tune the fixture. The image is too blue to make out the details/characteristics of the algae type. What type of algae does it look like? You're an experienced hobbyist so I am confident you have N/P in check. Is the algae just growing on dead skeleton or live tissue?

It is a Radion Gen3. I'm actually running zero red/green. White at only 10% max while blues at 100% max at peak time 12pm till 4pm. Otherwise ramping. Overall brightness 55%
It is growing on a dead area only. Looks to be HA type.
I've removed the algae via a soft tooth brush and increased flow a bit to the affected area. Hopefully the tissue will grow back maybe [emoji4]

Better pic with just the whites on. It's the green area on the left where the algae is growing.
