I spoke to Don Hourahane (he lives/lived in Roodepoort) some years ago, he spoke of a project in New Zealand. As far as I know nothing came of it. The materials used, are apart from the roving, are the same as many of us are using to make artificial live rock, namely cement and some form of calcium carbonate or aragonite.Hi Guys
Check out this for the rehab and construction of new reefs
To do this in our confined tanks appears to be a no-no as the processes leaches chlorine gass and some bad acids but. I spent hours surfing on this last night and even traced the patent, to start we need to look at this, imagine do this at Vetchs pier.
Hi Carl that is really interesting. I see that the advantage doesn't last if the current is switched off. I would love to see someone try it in an aquarium. You checked out the patent?Hi Rod
Good to see you here.
This form of artficial reef is using a metal frame with some low voltage DC trough it.
It uses the mineral accretion, or the Biorock® Process, by Prof Wolf Hibertz.
Copied from his website
Mineral accretion technology is a method which uses safe, low voltage electrical currents through seawater, causing dissolved minerals to crystallize out on structures, growing into a white limestone similar to that which makes up coral reefs and tropical white sand beaches. This material has a strength similar to concrete. It can be used to make growing artificial reefs on which corals grow at very rapid rates because the change in the environment produced by electrical currents speed up formation and growth of both chemical limestone rock and the skeletons of corals and other shell-bearing organisms.
