Need to stop GSP

okay i made the mistake of placing my GSP in the middle of my tank where it has, of course, spread considerably. i like it but want to stop its progress moving towards the left side of the tank. My RBTA seems to have stopped its progress going right and i would like to do the same on the left with perhaps a more aggressive coral (there is a narrow spot in the rock where i think i can place something to stop it). I guess I have two questions. First, what coral would you suggest. Second, am I asking for trouble with the chemicals that would be released by the coral fighting off the GSP. I know that i can continue to physically remove the portions that have spread but i haven't kept up and would like to put something in there to do the job for me if possible. Let me know if anyone has any suggestions. i know the "kill the weed" comments are coming but i don't want to get rid of it just stop the spread.


SAY

by the way, the area is about 8 to 10 inches below a six bulb T-5 unit with medium flow.

 

Sorry SAY, but short of nuking the tank or removing the problem rock, I can't help you. I tried to kill it by placing it in no light covered in sand upside down for 4 months and when I flipped the rock over it was still going strong!

 

lol! it must be stopped.

 

I have a Zoanthus colony on either side of my GSP...and it has definitely kept it in check.

 

grab a razor and a comfy chair, pull the rock out and cut as much off as u can.

 

really? i hadn't considered zoas. i guess that makes sense with the toxins they can release. thanks!

 

yes, i knew these comments were coming but i can't easily pull the rocks (yes, plural) out. i am looking for another way if there is one. otherwise, i will continue to physically remove portions. thanks.

 

get a razor blade and cut the matwhere you want it to stop. pull the unwanted parts off, attach to another piece of rubble wait 2 weeks and sell back to LFS(or send to D. Babcock,906 Argyle, Montreal, Quebec, Canada H*H-1*1;D)

 

no no NO! give it all to me ;D

 

been there done that.

IME, the GSP is also growing where you can not see it. It also grows under the rocks, out of view, to access other areas. It is quite possible you'll corral it in the center and then, one day, it'll pop up on the other side.

GSP does not need light to survive. It needs light to color up. (well it needs some light, but it seems to be fine if large stretches of it are in the dark and a whitish clear color).


When I got rid of mine, I thought I'd just have to pull one rock that it was growing on. It had turned out it was growing up inside and under that rock, through a hole in another rock and on the bottom side of several around it. It was a major pain but I am glad I finally nuked it out.
