Nutrafin’s Calcium Test measures calcium in fresh and saltwater aquariums. Marine reef aquariums, especially those containing hard corals and strong growth of coralline algae, absorb calcium at a rapid rate, often requiring daily testing to ensure that the calcium remains at an optimal level for the aquarium inhabitants.

The kit includes :

•  One 15 mL (0.5 oz) bottle of Calcium reagent #1
•  One 6 mL (0.2 oz) bottle of Calcium reagent #2
•  One 18 mL (0.6 oz) bottle of Calcium reagent #3
•  One glass test tube with cap
•  One pipette
•  One lab base
•  One instruction booklet
