Does it blow off easily? It looks a little like cyano.

Looks like cyanobacteria. Increase flow to the area, possibly feed less (or use less flake food), use RO/DI water for topoffs and PWC's, more water changes. It's probably excess nutrients in your water.

Blasting scally wag u got cyno mate lol very common when u overfeed or bulbs are more then year old or u don't do enough pwc

the wierd thing is i use ro water and i have plenty of waterflow in take (2 hydors 1050's. and it's growing in high flow areas. lol
i was maybe overfeeding but stopped, now just doing 1-2 feedings a day.
did a 30% pwc and things seem to have calmed down. but i still have some.
my light schedule has been reduced to around 4 hours a day. was 9 hours a day.

am i on the right path?
