My 75g tank is overgrown with the same razor caulerpa you gave me, Kim... At some point this week I will be undertaking a massive pruning because I have let it get a little out of hand. I should have set up a refugium and let it grow in there, but alas I did not (water under the bridge now). Anyways so you are of course welcome to as much as you'd like....re

As to the melting .... I think that sometimes it can happen without sporulating. I gave Jonathan prunings of the razor caulerpa on 2 or 3 separate occasions and it never took, he said it just disintegrated. It makes me think that if the stuff is cut, it can release something that is hazardous to it's own health. I am only speculating here, but I've been reading on RC recently about caulerpa and other macro algaes releasing "secondary metabolic inhibitors" (or some such) that negatively impact the growth of nearby SPS. If these metabolites or whatever they are are intended to impede competing macros then perhaps it is "not entirely a huge quantum leap of unfounded reasoning" to speculate that something is released that is not good for the algae (and hence itself too). If this is true then I am not certain what the steps are to prevent it when transplanting. Perhaps running some carbon...? ??? :? ???
