Hi everyone,
I’d like to open a discussion on the influence of magnesium salts—particularly magnesium chloride (MgCl₂) and magnesium sulfate (MgSO₄)—on coral reefs, both in natural ecosystems and in artificial reef restoration efforts.
As we know, magnesium is the third most abundant ion in seawater, after sodium and chloride, and it plays several key roles in marine ecosystems. In the context of coral reef biology, magnesium contributes to:
Skeletal Formation – Magnesium ions regulate the crystallization of aragonite (a form of calcium carbonate), which corals use to build their skeletons. Without sufficient magnesium, calcification rates may be disrupted.
Algal Symbiosis – Healthy coral relies on symbiotic zooxanthellae (algae) for energy. Some studies suggest magnesium levels can indirectly support photosynthesis efficiency in these algae.
Buffering Ocean Acidity – In certain controlled experiments, magnesium hydroxide and other magnesium compounds have been proposed as part of alkalinity enhancement strategies, which help counteract ocean acidification and promote reef resilience.
Reef Aquarium Practice – In reef aquariums, magnesium chloride and magnesium sulfate are routinely used to maintain ionic balance and support coral growth—demonstrating their practical importance even in small-scale ecosystems.
Has anyone here worked on coral restoration or artificial reef projects using magnesium-based compounds? Do you think supplementing magnesium salts in targeted marine zones could support coral regeneration?
Let’s discuss the science, risks, and potential of using magnesium salts as part of coral reef conservation strategies.
