Hi All,

I am always finding weird things growing from my LR. About 2 months ago
this stuff appeared that looked like green grape vines. Any idea what it
is? It has started growing everywhere and even though I cull it is is
starting to grow out of my corals and killing them.

Grape Caulerpa (Caulerpa racemosa). Nasty stuff in a display. Take the
rock out, and tweeze, tweeze, tweeze. If your tank is large enough, some
tangs will eat it readily.

Good luck.
