Ok so I have been to both of my LFS and they had no idea what this stuff was. The heads of it look like GSP except that these are brown, obviously. It encrusts over the rock in little veins and grows really, really fast. It is also extremely difficult to remove by hand, so my questions are what is it and how to I get rid of them.

boiling water mixed with lemon juice, careful not to od though it will cause ph 2swing

injecting it with kalkwasser works well too

its gsp but it doesnt always come in green. you can try getting a knife and cutting around the rock getting huge fragments of the colony off so u can keep it under control. boiling the rock would work. u could try selling it as a star polyp encrusted live rock.

it doesn't show from the pic but I have some orange rimmed zoas that popped up on that rock and I was trying to save otherwise the rock would have been out long ago, and romsoccer are you sure about it being a star polyp? The gsp encrusts in a lot different fashion then this stuff does. If that's true I almost want to go as far to say that this is a nuisance coral.

that is gsp dont inject it let it grow

yeah why do you want rid of it ? it is a star polyp

[northcoastdiver]

its getting pretty invasive and besides if you saw how much of the tank is already gsp I think you'd understand my plight :)
