How is a Biorock reef built?

Mon, 03/26/2012 - 03:36 -- admintps

To build a Biorock reef, an electrically conductive frame, usually made from readily available construction grade rebar or wire mesh, is welded together, submerged and anchored to the sea bottom. Sizes and configurations are infinite and are varied to fit the setting. A low voltage direct current is then applied. (Power sources can include chargers, windmills, solar panels or tidal current generators.) This initiates an electrolytic reaction causing mineral crystals naturally found in seawater, mainly calcium carbonate and magnesium hydroxide, to grow on the structure.
