+To build a Biorock reef, (developed by Thomas Goreau and Wolf Hilbertz in the 1970's)  a low voltage electrical current is passed through a conductive frame (metal meshes) that’s anchored to the seabed. Power can be sourced from chargers, windmills, solar panels or tidal current generators. The electrolytic reaction causes mineral crystals such as calcium carbonate and magnesium hydroxide found in seawater to grow on the structure. Within days, a whitish hue that is made up of precipitated minerals coat the structure’s surface – a sign that the wired frame is ready for action. Divers then begin transplanting coral fragments from other reefs and attach them to the frame. The coral pieces begin to bond to the accreted mineral substrate immediately and start to grow at a rate up to five times faster than usual. Soon the frame with dotted corals becomes a habitat for a reef ecosystem, attracting colonizing marine life such as fish, crabs, clams, octopus, lobster, and sea urchin.\\
