Even though we attempt to mimic natural ocean conditions in our aquariums on a daily basis, it often helps coral growth to step away from natural conditions to some extent. For example, calcium and alkalinity are often found at rather modest levels on the reef when compared to those levels in the aquarium. Reef keepers use various additives to increase the concentration of these elements, and the corals usually respond by growing at a faster pace. It is commonly believed that aquarium alkalinity levels of 11 dKH provide the best conditions for the fastest growth, along with calcium exceeding 300ppm and holding steady above that number.
