After todays FMAS meeting discussion, simply take some fishing line and hang frags in your aquarium. Away from predators and algae, actually you can have all the algae you want at the bottom 
I would like to see someone try this. In a nut shell they tried frags in 3 different ways and hanging them was the fastest and with 100% success, here is some credentials from the speaker and some photos from the meeting.
Here is who grows corals suspended

Research: My work focuses on the growth and culture of the staghorn coral, Acropora cervicornis. Specifically I am investigating differences between line nursery culture, in which coral fragments are grown suspended in the water column, and more traditional fixed nursery methods where coral fragments are secured to growth plates/pucks. The line nursery I engineered and installed to test these differences has produced material for thousands of fragments, which have already been used for a variety of purposes, including fellow student projects and educational exhibits.
