API Calcium Test Kit

Calcium is one of the most important elements in a reef aquarium. Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy. Over time, calcium levels drop as invertebrates use calcium in aquarium water. This kit allows you to easily and accurately measure calcium levels and maintain a healthy reef aquarium.

Kit contains:

  • Two dropper bottles for accurate dispensing of test solutions, easy to read instructions and a color chart, a non-staining glass test tube with snap-tight cap.
  • Measures calcium levels as low as 20mg/L
  • Uses titration method, with easy to see color change for precise measurement.
  • For use in Saltwater Aquariums or Ponds
  • Performs 90 tests
