Purple, tufts, small, slow growing algae, need help identifying.

[therremans]

I am wondering if this slow growing purple algae should be something of concern. It sticks to the rocks well in small fibrous tufts and I haven’t focused on it’s removal since it grows so slowly. I could not find out what it is. I actually like the look of it..

thanks!

I see wire algae first pic and what may be chrysophytes which will need to be scrubbed off

Okay, I was able to scrub it all off. It was extremely tough algae, reminded me of a scotch brite 3M scuff pad. I used a brass brush to get it off the rocks and even with metal, it took many passes. I’m glad I reacted now vs later when it could have became an issue.
