Another light source in reef aquariums is metal halide lighting. These high output lights closely recreate the shimmering effect of bright tropical sun over a patch of coral reef. Metal halide bulbs come in a variety of spectra from 5000k on up to 20,000k and allow for a variety of light-hungry corals to survive under them.
An algae scrubber is a water filtering device which uses light to grow algae; in this process, ... [coral growth] rates equal to the best 4 percent of wild reefs, and ...
Mesophotic coral ecosystem in the Marshall Islands. Photo by Luiz A. Rocha.. A mesophotic coral reef or mesophotic coral ecosystem (MCE), originally from the Latin word meso (meaning middle) and photic (meaning light), is characterized by the presence of both light-dependent coral and algae, and organisms that can be found in water with low light penetration.
The Great Barrier Reef (GBR) is most likely the most famous and largest coral reef, and it is facing many of the same problems. In the related coral nurseries, the results can be highly variable depending on the types of coral and the conditions but overall show the same or higher growth rates than the natural coral reefs.
However, many organisms see negative effects on growth at saturation states above Ω = 1. For example, a saturation state of Ω = 3 is optimal for coral growth, so a saturation state Ω < 3 can potentially have negative effects on coral growth and survival. [10] Calcium carbonate saturation can be determined using the following equation:
The branching structure creates habitat and shelter for many other reef species. Elkhorn coral is known to grow quickly with an average growth rate of 5 to 10 cm (2.0 to 3.9 in) per year. They can reproduce both sexually and asexually, though asexual reproduction is much more common and occurs through a process called fragmentation.
