Red and green algae

[Jamie805]

Hello. I have a 36g bow front saltwater tank. Fairly new at about three months old. I have 2 clowns, 2 firefish, a sailfish, and small blue damsel, and a banded shrimp and about 10 snails. Not sure what type. Google says tectus snails. I have red algae growing on the substrate and green on the rocks. My question is do I need more of a clean up crew or do I need to treat the tank? I also have algae hard algae frowning on the glass that a scrubber won’t remove. Feels like fine sandpaper. Any suggestions? Thank you in advance. Also tried to get rid of the red algae with a gravel siphon. No luck.

Is it like slime or dust?

It may be cyano. This thread may be helpful:

Thank you. It is more slime than dust.
