What type of algae is this?

[150 Gallon Reef]

Like the title states. It is rough feeling and difficult to get off the rock. Never gets long and stringy like GHA. What can I do to curb it? I treated it with revive a few months ago and almost eliminated it. But my corals really didn't react well to the treatment so I stopped it. I was thinking a tuxedo urchin? Dr tims? Phosphates I keep around .05 to .08 and nitrates between 8 to 16 ppm. Tank is about 8 months old but rock came from an established tank.

It’s turf algae. . Very difficult to battle. Pull as much as you can by hand or if you can pull the rock, scrub it and use a dental pic to pull the roots out.
Reduce white light intensity and add some cleaners such as chitons, urchin, astre snails, conch and carrbean blue leg hermits

There are several fish that should eat that. A fox face rabbit fish or several different tangs would top my list.

I've pulled out so much previously but didn't seem like it made a dent. Do urchins normally eat turf? Would 2 suffice in a 48x24 tank or is that overkill with more than 1?

3rd vote for turf algae. I've got it in a few places in my tank now, but not super bothered by it.

Corals will grow over it as they encrust and shade it out as well, and it wont choke them out like GHA does.

Manual removal once it grows enough so that you can get a grip on it, seems that once you pull a chunk off the rocks it doesn't grow back so long as you get the roots.

Hermits don't seem to help very much in my experience, but I did get a Foxface that is starting to clear it up and he showed my YT that it is edible lol.

But I agree that its tough to remove like GHA, you don't get that satisfaction pulling out huge clumps.

I have the same problem. I got a purple pin cushion urchin and he doesn't touch it at all......only eats my Coraline I bought it to get rid of my turf algae and it hasn't helped.

Same here. I got a Tuxedo urchin to eat it and hasn't touched it's short or long. It has removed coralline from rocks that were completely covered in coralline.

So I picked up a tux urchin and a couple turbo snails today to see if they help with it. I'm hoping they are able to do something with it. I really dont want to use vibrant again....
