I’ve had some pretty rapid growth of what looks like coralline algae but feel slick to the touch and is dark red. This stuff doesn’t come off easily and requires a metal tool to scrape it off.
I’ve ignored it in the past thinking it was coralline but now I’m in the middle of a chemiclean treatment and I noticed lots of stringy stuff coming off. Is this normal for coralline or is this something else?

During Treatment:
Any thoughts on what this is?
