gsp rock

I need to get unload a piece of GSP. I already have some and want to add something else in its place. It's encrusted on piece of live rock 5"x7 (give or take) which I placed it on a dryrock ledge four months ago. I dipped it before placing in my tank and it's suspended about 14" from the sand...

Hello everyone, I was wondering my GSP over the past few weeks blew up and is not stopping to grow (Not that its an issue) i don't want it to overtake the whole tank, Is there a way to stop them from growing, or to control how they grow? Thanks in advance.

My gsp has completely covered the small rock I have it on and is now growing “limbs” I guess (not indovual polyp tubes) out of itself. Is this what the branching variety does? Like the purple mat has little trees or purple with multiple polyps on it growing off it.

I got this GSP as a small piece inside a zoa frag. It’s growing big growths off the edges of the colony. Is this the branching variety GSP or is it the normal one?

I’ve got a big chunk of gsp that started out as a tiny 0.5” sized peice I pulled off a zoa frag. It’s starting to grow “branches” or bug tubes off the purple mat and getting super long. Is this the branching variety? First GSP I’ve ever had. Always avoided it like the plague but I really wanted...

Have a nice rock with green star polyps on it. I’m guessing rock weighs 5 lbs? About 8” x 10” X 4” rock. $25 Pick up only. Naples I started gsp on this rock to grow up onto glass wall of tank. Mission accomplished, so rock can go.
