Reef Restoration

The reef ecosystem in front of Manta Dive Gili Air has grown considerably in the last 10 years.  We have aided in its restoration by adding biorock structures to give additional protection for the delicate reef ecosystem.

The science behind the  Biorocks 

The biorocks are basically a metal structure that provides shelter and structure for corals and fish to live.  They are then connected to a low voltage current (of course not harmful to snorkelers etc) which creates a reaction that speeds the formation of calcium carbonate, or reef, as we know it.  This then coats over the metal structure and secures any broken corals that have been attached to it in place.  Then the corals can firmly attach to the structure and continue to grow.  This works perfectly here as pieces broke by anchors and divers can be recovered and relocated on a biorock to survive.  

The biorocks most enjoyed from snorkeling depths, as they range from 1 m to 3 m depth.  Please come visit our growing coral garden at Manta Dive Gili Air, but please be respectful to the growing corals.  No touching, no taking, and please, no standing on the reef!
