Fluval Sea Calcium can provide a concentrated form of calcium for your aquarium. It can be easily absorbed by invertebrates like corals and others for a strong skeleton structure. This calcium formula works without affecting the sensitive ionic balance in an aquarium and still provides necessary calcium required. You can use it to counteract constant depletion of calcium by corals, coralline algae and other invertebrate growth.
