that is what my original plan was with the prolifera, but i just got a second tank and I am going to plumb it to be a display refugium.I had a huge caulerpa prolifera "field" in my 75g display fuge years ago. I wanted a clear area to feed the angler that lived in its grassy depths so i just pulled it from that area on a regular basis. Probably every few days. It does grow fast. I have heard it can go sexual but In the 6-7 years I had that set up it never happened. I have had a very hard time finding any now that I'm back in. I had to settle for the mexicana "feather" caulerpa this time around and its growing so well I wouldnt have the heart to pull it if I found the prolifera. Also dragons breath is really nice too. Codium is cool I didnt know years ago the codium is supposedly a cooler water species. Might be why mine lived but never really grew well. I love the idea of things like mermaids fans and shaving brush plants I just never had great luck with them. They usually look very drab and ehhh.
