Why don't you just use a pair of tweezers and get them out physically? You said you only have 2? That is what I would do, I don't like chems in my tank.

...Kalk's commonly used as a calcium and alkalinity supplement in the hobby. 100% reef-safe when used properly.

I find it funny how people don't want to put 'chemicals' in their tank, but use artificial salt mixes. %)

I thought about taking the colony out but it was attached to my main rock and I didnt want everything to collapse.

I ended up squirting the calk into its mouth yesterday. It hasnt opened up since. I think they are goners! I feel a bit bad but their sting was killing my other corals.
