Algae id

[Coleb]

What kind of algae is this and should I remove it from my tank. It's on some of the rocks

 

[brandon429]

it is your choice to remove it


Here's a tank we are working on via pm that didn't:

nice coralline you have there
I'd lift out any rock with that ? species of rhodophyta and put peroxide just on the algae parts, let sit for a few mins in the air, won't harm rock, put back in. takes a week to die, turns hot pink color first

zap it imo
