Help with the Red algae ID please!

[JorgeS]

Does anybody knows what kind of algae this is? And what caused it? My nutrients are in check, I’m actually dosing a little phosphate, have it now in 0.08 and No3 in 2.5-5.
I don’t have a lot but it is very difficult to remove from the rock as it attaches very strong.

looks like a macro, maybe some gracilaria? if so idk if thats a sign of a water quality issue so much as it is annoying to pull it off. Could be cool looking

Red macro maybe Gracilaria or Halymenia, not sure. But I’d leave it. I consider that a desirable algae, not only looks pretty but helps with nutrient control.

Yes, it looks like a type of macro algae. You may enjoy having it if you don't mind pruning it occasionally.

Yeah I have the same in my tank. I had to prune back one rock it was getting kind of thick like a red carpet.
