Help identify/kill red hair or turf algae

[atlfishes]

I'm pretty sure I don't want this in my tank. Came in on mushroom frag about 8 months ago and really hasn't spread much except on the original rock. I've read a few articles and now I'm worried this could be some bad stuff.

Best way to kill if I can remove the rock from the tank and dip into some mixture. Concentrated kalk?

If its on a rock that I can't move? Again, I could turn off the flow and put some concentrated kalk on it (only for small new sprigs)?

I'll probably cut of the big piece seen in the pic with a dremel.

Any specific invert eat this? Thanks

Looks like the red turf I had, you can see mine on the rockwork behind the clown:

Lot's of phosphate media (RowaPhos) and Turbo Snails put a dent in it. Be proactive and get it out now, it's a major PITA.

For me, XXL Mithrax crabs and red scarlet leg hermits worked beautifully. Or a tank crash.
