FYI the person behind this concept is a Pace University Faculty members in Biological Sciences who started this in Antigua - I believe I have the white paper somewhere (if not already here and search able on MR).
I'll see if I can find the actual paper and post it up.
The thesis is exactly that - coral skeletal growth increase with low, and I mean low, voltage - has something to do with the way calcium carbonate forms - a very novel and interesting concept. Perhaps our resident scientist, Solbby, can shed some light on this topic.
wasn't this started awhile ago? I remember hearing something about the low voltage current also attracting planulae to the bars while also causing it to encrust faster by pulling the calcium out of the water column. Wonder if a scaled down version is possible..........
