A
Acropora is a genus of SPS coral known for its branching growth forms, vibrant coloration, and fast growth potential. Often considered the pinnacle of reef keeping, Acropora corals rely on stable water chemistry, strong lighting, proper nutrition, and consistent conditions to thrive.
Alkalinity is a measure of the water's ability to resist changes in pH and is one of the most important parameters in a reef aquarium. Corals use alkalinity as a key building block for skeletal growth, making it essential for coral health, stability, and long-term success.
Amino acids are the building blocks of proteins and play an important role in coral growth, tissue repair, coloration, and overall health. Corals obtain amino acids through feeding and direct absorption from the water, making them a key component of reef nutrition
B
Bioavailability refers to how easily a coral can absorb and utilize a nutrient after it enters the aquarium. A nutrient may be present in the water or food, but if the coral cannot efficiently use it, its bioavailability is low.
Broadcast feeding is a coral feeding method where food is dispersed throughout the aquarium water column, allowing corals and other filter-feeding organisms to capture nutrients naturally. This approach closely mimics how food is delivered on natural reefs.
