killing coral (on purpose)

[Myka]

Boiling water is least likely to affect the rest of your tank.

Has your tank cycled yet? If not, the cycle of such "fresh" rock will kill it off.

Oh yah, the tank is a year old. About 70% of it died during the cycle, but there were enough surviving patches close enough together that in the past year it's just filled back in over-top of the dead stuff, there's more of this coral than anything else in my tank now. I'll probably try the kalk paste first, I hate the look of epoxy and this stuff grows over the epoxy I use to cement my other corals faster than the corals I'm trying to epoxy in to place!
