Why Test for Calcium in the Aquarium Calcium is one of the most important and the basic building block in a reef aquarium. Living reef invertebrates such as corals, crustaceans, mollusks and even some types of ornamental algae need calcium to grow and remain healthy shells and skeletons. Over time, calcium levels drop as invertebrates use calcium in aquarium water. Calcium should be maintained in a marine aquarium at levels of between 350-450ppm. This kit allows you to easily and accurately measure calcium levels and maintain a healthy reef aquarium.
