Biorock®/ Mineral Accretion
• On underwater, conductive structures we assemble a positively charged anode and a negatively charged cathode (structure)
• Apply a low voltage electric current between them
– Safe for swimmers• Which causes minerals to crystallize from seawater onto structures
• Calcium carbonate, white limestone (CaCO3) is formed-Similar to natural coral reefs and tropical white sand
• Corals adhere to limestone and grow quickly

How a Biorock® Reef works
Cathode (-)Conductive Structure
Anode (+)
Solar collector or other power
supply
(CaCO3)
When a positively charged anode and a negatively charged cathode are suspended in sea water with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).The result is calcium carbonate.Corals adhere to CaCO3 and grow quickly.

How to build an electric reef• Design the structure
• Assemble the structure from conductive materials
• Submerge the structure• Attach anode material• Attach wires from solar panel or voltage
generator• Turn on current• Watch for bubbles
– Signifies limestone forming• Attach coral fragments• Watch the coral grow

Designing a structure
• Designs take into account depth, wave action, ocean bottom characteristics and aesthetics
• Structures are easily built with locally available conductive material (usually rebar)

Considerations for building
a Biorock Reef• Depth of water• Type of ocean bottom• Distance from shore• Availability of electric power• Availability of broken coral fragments
• Dedication to maintaining reef operation
• Funding

Biorock corals
• Grow 3-5 times faster• Heal more than 20 times faster• Survive high temperatures 16-50 times more
• Have hundreds of times more baby coral settlement
• Attract incredible numbers of fish

• Corals can survive under lethal conditions
• Reefs can be quickly restored where they can’t recover naturally
• Fishermen can grow reefs and greatly increase fish and shellfish populations and catches, becoming farmers instead of hunters
• Breakwaters can be built for a fraction of the price of concrete or stone, with vastly greater environmental benefits

In the Maldives
• Biorock reefs turned severely eroded beaches into 15 meters growth in two years
• All Biorock corals survived the tsunami undamaged
• Surrounding reefs had massive corals fall and table corals break.
