Red stuff growing on my rocks

[mmurphy]

Hello, I need help. Can you tell me what this red stuff is? It's talking over different areas of my rocks

Does it blow off with a turkey baster?

Please be a little more conservative when you use the tag “emergency”. That is mean for true emergencies (fish heavy breathing, dying fish, tank leak, etc…), this is just algae…
