Help with identifying this on my rocks.

Is this Cyno or Coraline? I try and brush it off with no luck.

Correct… It’s been running for around 1 1/2 years.

Coraline

I hope!! But I get it’s Coraline and it’s Cyno… I just know Cyno brushes off easily.

Looks like coraline to me as well but a closer shot may help too

After hearing it may be red slime or cyno, I went out and bought some additives to get rid of those things and after using them, I didn’t see any difference. This makes me think that it should’ve made some difference maybe not all gone but something.
