Best way to cull a polyp herd

[Rybren]

I have a whole raft of some kind of polyp in my tank.  (see pic) The colony is expanding quite quickly and I'd like to be able to control its expansion.

I know that the best method would be to remove the rock that they're on and then remove the polyps, but because they're on the lowest rock in the tank, it's not a great option.  So my questions are.... 

a.  what is the best way of removing them while in tank?
b.  should I be concerned about a toxin release, and if so, what can I do to minimise the effect?
c.  should I forget about population control?

Thanks,

Jerry

just a guess... mix some kalk water and put it into a syringe... carefully squirt the ones you want to kill right in the face... a drop or two should do to burn them back...

it'd try it anyhow... infact i might try in on some GSP.

There is no way GSP would let you do that to him. He'd take you down with a judo throw and proceed with some ground and pound! 

Or maybe you mean green star polyps... I am still high off UFC 100 this past weekend.

Lol.. nice.

I wish my GSP grew fast enough to have to kill it. (of the star polyp variety, not the St. Pierre variety) Maybe its too low in my tank?

Assuming I try Tim's Kalk suggestion, what are the expected side effects?

As an aside, I can't get my GSP to do much of anything either.

There should not be any side effects to the rest of your tank since you are using a small concentration of kalk per polyp head. This is a method I've used regularly to kill aiptasia as well.
