Compared to fish‐only marine aquariums, coral reef aquariums require more intense lighting of the correct spectrum, turbulent water movement, and more stable water chemistry. Biological filtration for reef aquariums usually comes from the use of live rock from around existing reefs or from aquaculture. Foam fractionation and deep sand beds are also often used. Calcium injectors and reactors are often used to maintain proper pH, alkalinity, and calcium and magnesium levels that are critical for stony corals to maintain their calcium carbonate skeletons. Dedicated computers with electronic water quality monitoring capabilities may be used to control water chemistry parameters in complex systems.
