Authors: J. Charles Delbeek & Julian SprungScience, Art & TechnologyReefkeeping science involves the interplay of biology, chemistry, and physics. However, a reef aquarium is not simply a product of scientific knowledge. The application of engineering and its product technology, makes it possible to duplicate the specific biological, chemical, and physical requirements of a coral reef in a relatively small volume of water. This third volume in The Reef Aquarium series provides the most thorough description of the science behind the creation of a captive reef, and critically reviews and explains the different philosophical approaches to reef aquarium design. It also describes and illustrates the existing as well as emerging technology for building reef aquariums, to help guide the selection of equipment, its proper use, and installation.
