What is this thick red algae

[ReefNewbie12]

Yeah, I got no words here, it seems to have sprung up randomly (like all the worst algaes do) and didn’t appear near a frag or anything, what is this? Is it some sort of super-cyanobacteria? Will it harm my corals or snails? (I’m afraid the latter would probably eat it regardless) And most importantly, if it’s not cyano, how do I get rid of it? It’s growing on both the sandbed and the rockwork.

Typical cyano. It comes and goes from time to time in my system in small amounts.

Thanks! I suspected it was cyano but wasn’t sure since it‘s so vibrant.
