Calcium is one of the most important elements in a reef aquarium.

Over time, the calcium level drops as it is used by invertebrates, or as 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. Contains 2 test bottles, easy-to-ready instructions, and glass test tube.Best Before Guarantee: 28/04/2027
