Calcium Test Kit

Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals and crustaceans, need calcium to grow and remain healthy. The calcium level gradually drops in reef aquariums as invertebrates utilize calcium in the water.
This kit contains: 2 liquid dropper bottles with child-resistant safety caps, easy-to-read instructions with information on how to test and how to correct unsafe water conditions, and glass test tube with snap-tight cap.
