How do you anchor a Biorock reef?

In most coral reef environments, structures sit on limestone bedrock where they eventually cement themselves solidly to the hard bottom. Usually structures are held in place against wave forces by their own weight or by filling them with rocks. In hurricane regions, where there is a tradeoff between how long it takes to get the structure solidly cemented to the bottom and when the first hurricane hits, we drill holes for vertical rebar supports; a couple of feet is usually adequate. In sand, we anchor reefs using rebar pounded into the substrate.
