The way I see it, if the limestone builds on the structure first, then Corals grow on limestone. You just chip off limestone/coral and voila, a frag to relocate. Or, just take clippings off, utilizing the 3-6x growth rate. A little structure in the corner of ones tank could be used to propagate frags continously. No need to worry about turning the electricity off, leeching etc. just keep growing. Also, for frag businesses, this could mean a great help. Set up complete tanks with mesh growing surfaces in them.
