Well, luckily there was a great summary published in Febuary "The Biology and Economics of Coral Growth" Osinga et al. 2011 It was actually published as an open-access journal article, so it is available to everyone and is really good review of the factors that influence coral growth. It is intended to be used for cost benefit analysis for the aquaculture industry. And is a bit technical, but you can skim through and should be able to pick up on the main ideas.

Wijffels, Johan A. J. Verreth, Shai Shafir, Stéphane Henard, Maura Taruffi, Claudia Gili and Silvia Lavorano Abstract To protect natural coral reefs, it is of utmost importance to understand how the growth of the main reef-building organisms—the zooxanthellate scleractinian corals—is controlled. Understanding coral growth is also relevant for coral aquaculture, which is a rapidly developing business. This review paper provides a comprehensive overview of factors that can influence the growth of zooxanthellate scleractinian corals, with particular emphasis on interactions between these factors. Furthermore, the kinetic principles underlying coral growth are discussed. The reviewed information is put into an economic perspective by making an estimation of the costs of coral aquaculture.
