Calcium is a crucial component in a reef aquarium. Invertebrates found in reefs, including corals, crustaceans, mollusks, and certain types of encrusting algae, require calcium for their growth and overall well-being. As time passes, the calcium concentration can decrease due to consumption by invertebrates or its reaction with excess phosphate. The API® CALCIUM TEST KIT is designed to measure calcium levels as low as 20 mg/L, ensuring the health of your reef ecosystem.
This kit includes 2 testing bottles, straightforward instructions, and a glass test tube.
