While very useful to reef aquarium keepers, halide lighting also uses a lot of electricity (150-400 watts being common) and produces copious amounts of heat. Most reef keepers mount halide bulbs at least one foot above their tank and some, due to the lights' heat output have had to add chillers to keep aquarium water cool.
A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine ...

When oil floats above the coral reef, it will have no effect on the coral below, it is when the oil starts to sink to the ocean floor when it becomes a problem. The problem is the physical effect from the oil-sediment particle which has been found to be less harmful than if the coral came in contact with the toxic oil. [103]
The Temple Reef Foundation was founded in 2017 to support marine conservation and the further development of artificial surfing reefs in the area. In 2019 Bennington's Reef was added to the Temple reef dive site using a patented design for cement-dolomite blocks. The initial block was 3D printed, and further blocks were built using molded frames.
A chase is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights moving along the string. With computerized lighting consoles, building chase sequences has become easier, while previously chases used mechanical means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit.
The reef lights were intended to mark local hazards and did not need to be visible for as far as the reef lights that were erected near the Keys during the 19th century. [ a ] By the time the lights in this list were erected, older lighthouses were being automated, and these new lights were designed to be automated from the start.
The lighthouse was added to the National Register of Historic Places as Penfield Reef Lighthouse in 1990. [ 1 ] [ 12 ] In 2015, the Coast Guard executed a substantial rehabilitation project at the lighthouse, designed by architect Marsha Levy of the Coast Guard's Civil Engineering Unit Providence, to address the damage from Hurricane Sandy.
