API Calcium Kit for Marine and Reef Aquariums CA Test Kit
The API CALCIUM TEST KIT measures calcium levels as low as 20 mg/L to
help you keep your reef inhabitants healthy. 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 remain healthy. Over time, the calcium level
drops as it is used by invertebrates, or as it reacts with excess
phosphate.
Includes 2 test bottles, easy-to-ready instructions, and glass test tube.
For Salt Water Aquariums.
