Calcium
Essential for coral growth and skeletal formation in reef aquariums. Calcium is one of the most critical elements for a thriving reef aquarium. It is an essential building block in the formation of calcium carbonate, which makes up the skeletons of SPS and LPS corals, as well as the shells of invertebrates and coralline algae. Without sufficient calcium, coral growth slows, and overall health can become compromised. Maintaining stable calcium levels ensures consistent skeletal growth, vibrant coloration, and strong biological processes throughout your reef system. Together with balanced alkalinity and magnesium levels, calcium forms the backbone of a healthy and stable marine environment. Key Benefits:• Supports coral skeletal and shell formation• Promotes healthy growth of SPS, LPS, and coralline algae• Enhances overall reef stability and vitality• Prevents calcium depletion that can slow coral growth• Works synergistically with alkalinity and magnesium Recommended Levels:420–460 ppm
