The first thing that comes into mind when establishing a reef aquarium tank is the aquascaping concept with the addition of live rock. In the past, all these were actually harvested from the ocean and because of controversies surrounding conservatory efforts and sustainability concerns, live rocks were artificially cultured in large marine aquatic farms and then offered for sale in local .
It really depends on how detailed and technical you want. A good book for general audiences is the Audubon's Guide to North American Rocks and Minerals. This was helpful when I had mineralogy. I would recommend an older edition of Dana's Minera. Developing useful narrative biological criteria is the first goal in this process which could evolve into numerical biological criteria and quantitative thresholds for coral reef protection.

RocknReefs offers individual corals, Pangea America seagrass, kelp and algae, and custom fabricated coral reef inserts and themed environments for nature centers, public aquariums, large private installations and government environmental awareness projects.
RocknReefs hand fabricates our synthetic coral reefs and themed environments using AZA certified materials. About the Rock The rock is mainly formed by the sedimentation of calcium and limestone from an ancient seafloor, but there are 3 distinct types of rock that we come across.
The first type of rock we quarry is formed from ancient corals, tube worms and other forms of sea life. Overall, our reef network is designed to maximize the benefits of the materials that are available to us for reef construction.
The primary criteria that determine what materials are placed on a reef are depth and distance from the ports of New York or Philadelphia. Reef site depth dictates the height of the structure that can be sunk there. Degradation of the Great Barrier Reef overwhelmingly meets the criteria for an “in danger” listing by Unesco, according to a joint report.

You can use it as a guide in setting up your saltwater aquarium or use it as a species reference when visiting the local fish store. A reef is a bar of rock, sand, coral or similar material, lying beneath the surface of water.
Many reefs result from natural, abiotic processes—deposition of sand, wave erosion planing down rock outcrops, etc.—but the best known reefs are the coral reefs of tropical waters developed through biotic processes dominated by corals and coralline algae.
Sedimentary rocks form when sediments are compacted and cemented together (Figure below). These sediments may be gravel, sand, silt or clay. Sedimentary rocks often have pieces of other rocks in them.
Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. This sandstone is an example of a sedimentary rock. Discover Book Depository's huge selection of Rocks, Minerals & Fossils Books online. Free delivery worldwide on over 20 million titles.
