API Calcium Test Kit

Helps monitor calcium and prevent invisible water problems that can be harmful to coral & crustaceans

Keep your aquatic life healthy and thriving by testing your aquarium water's calcium levels regularly with this easy-to-use API CALCIUM TEST KIT for aquariums.Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. Calcium is one of the most important elements in a reef aquarium. Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy. Over time, calcium levels drop as invertebrates use calcium in aquarium water. The API CALCIUM TEST KIT measures calcium levels as low as 20mg/L. It contains two calcium test bottles, capped test tube and instructions. For use in reef aquariums.

Instructions of Use

Monitoring calcium levels is essential for keeping a successful reef aquarium. Corals and reef invertebrates, such as shrimp, crabs, mollusks, and encrusting algae require calcium to grow and remain healthy. The calcium level drops as it is used by invertebrates or as it reacts with excess phosphate. Having an adequate calcium level is not enough to achieve healthy coral growth, because the growth of corals is linked to carbonate hardness (often referred to as KH or alkalinity). All reef organisms rely on the combination of calcium and carbonate to build their skeleton structure by extracting these substances from saltwater. These two building blocks are essential for the growth of corals, crustaceans, mollusks, and coralline algae, so testing for both calcium and carbonate hardness is necessary for successful reef keeping. Note: reef aquariums should have a calcium concentration between 400 to 500 mg/L (ppm).
