CALCIUM TEST KIT
Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, mollusks, and even some type of encrusting algae, need calcium to grow and stay healthy. Over time, the calcium level decreases as it is used by invertebrates or when it reacts with excess phosphate. The API® CALCIUM TEST KIT measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy. sizes Contains 2 test vials, easy-to-read instructions, and glass test tube
