Algae

[Cmags305]

This algae is growing on my sand and I'm trying to identify what it is. Any help is appreciated, tank is 9 months old.

Looks like possibly Dino's to me. Is it stringy in some areas?

To me, it looks like red slime algae. If I'm right, here are some steps you can take to get rid of it:
Do water changes more frequently.
Siphon the affected areas when doing a water change.
Do not overfeed fish.
If you can, increase water circulation throughout th aquarium.

Looks like a combination of diatoms and cyano.
