algae/bac 1-2mm light brown film growing on rocks. Flakes off easily

[bearman88]

Reefer 250 (65g) - 5 months old. I feed very lightly every other day, on top of weekly water changes. Not running carbon/GFO or any other filtration besides skimmer. Water temp has been around 77-78.5, with ~0.05 PPM nitrates/phosphates. 3 small fish, standard CuC so I feel my bio load is low. Weekly 10% water changes.

This stuff is growing exclusively on my rocks and power heads - not so much on aragonite/sand.

When you hit it with anything - it flakes off super easily and looks like flake food floating around.

Any ideas?
