What are these globs under my GSP?

Anyone have idea what these brown globs are?

I'm gonna say bubble algae...

Yep, bubble algae. Just manually remove what you can before your next water change and keep your eyes peeled for more. The trick is with these things is that you need to stay ahead of them.

Do they just pull off or do I have to use something sharp to remove them. Also is the anything preventive I can do to keep them at bay?

I've glued a small bit of plastic to a siphon so I can suck them straight out as I knock them off with the point. I find 1 or 2 every now and again, but have never caused me a problem as I keep on top of them.

Definatlly bubble alge. Emerald crabs will help get rid of this. Be careful when removing these. Breaking the bubble will release spores and cause it to spread. I use a half inch tube with the end cut at a 45 to syphon them off the rock.

Sometimes if you wiggle them back and forth they'll come right off, but if they've dug in deep your going to have to use a little force to remove them. As far as keeping them at bay goes some fish will eat them, but in most cases these fish get pretty big. (Foxface, Tangs) If you can't house them properly then you'll have to look elsewhere for some help. Also, Emerald crabs have been known to eat bubble algae too, but there's really no guaranty this will happen. There's also reports of these crabs eating corals too, so you'll want to pay close attention them.

Keep nutrients (phosphate/nitrates) low.. Just like any other algae..

Bubble algae is common in many new tanks along with a host of other algaes.. Provided you keep those nutrients low (via water changes or other forms of export) then they like all other algaes will have no real food source and disappear or stay very manageable
