What is this stuff?

[Coasting]

Its really annoying my GSP, is it some type of sponge or algae?
It makes it hard for the polyps to come through it. Can I just pick it off or is there a better way to get rid of it. It is only on this Piece of gsp thats in my sand, so I'm assuming it came in with it, its slowly grown over the past 3-4 months to this size. Now its just really bugging me because I want the gsp to spread, not this stuff

Thanks.

It kinda looks like an algae
I can't quite make it out in your pic
If it has bubbles, don't burst them when you pick it out or it will spread spores

If you pick at it, is it fairly course or tough? Look up red turf algae.

I dont know if this picture is any better, me and the bow front are still working out our picture issues....
Will pull it out next time i do a wc and poke at it in the old water bucket.

When you have it in the bucket, pick it off at the base with some tweezers, then shake it really well before putting it back in the DT

Its red bubble algae, you could try removing as much as you can with tweezers try to trim it to the root, then when the polyps are all closed up give it a dip in hydrogen peroxide mixed with salt water. I would do a 2/3 peroxide to saltwater ratio and leave in for 2-3 mins, the GSP is pretty tough and aslong as the polyps are all closed and not showing the skin of the GSP will be able to withstand the dip. After this you may want to use a tooth brush and some of that same water to scrub gently the infected area so as to make sure it hits the algae even more, good luck.

Alternatively you can use scissors and cut off the infected part, GSP will grow back no problem...

Looks more like a red macro algae similar to Halymenia, doesn't really look like bubble algae to me.
