CoralAID. Applied Mineral Accretion Technology

Over the last decennia, coral reefs have become increasingly threatened in their existence. Global warming, water pollution and water acidification to name a few, are known factors inducing this situation. The importance of every effort to change these factors for the better is evident, but whatever can be achieved, given the alarming rate of coral decline, may be achieved too late.


This is where CoralAID is aiming to help. With applied Mineral Accretion Technology it’s possible to enhance coral growth and its resilience in less favorable circumstances. The technique is based upon Impressed Current Cathodic Protection which means supplying a constant (low voltage) current to a conducting substrate, using modern titanium-ceramic anode material. Furthermore, the technique is inspired by the research of the late Prof. W. H. Hilbertz.


In 2015 several prototypes were built and tested to develop the best possible application for a variety of situations. This included some specific innovations like auto adaptation for changing circumstances concerning variation in water flow, salinity, substrate conductivity, light intensity and temperature.


On this website all the technical data will be available for anyone who is interested. Feel free to use it in any way you see fit and experiment as much as you like. After all, that’s what CoralAID is all about.
