The API Calcium Test Kit is ideal for use in reef aquariums. Corals, crustaceans and invertebrates take calcium from the water and use it to fortify their calcerous skeletons. Calcium levels are quickly depleted in a busy aquarium and must be maintained.
This handy kit allows you to easily test the calcium levels and is able to determine levels as low as 20mg/l. The box includes detailed instructions on how to complete the calcium test and a user friendly colour chart to help understand the results.
Use a suitable calcium supplement to top up and make sure that your reef has everything it needs.
