Calcium is the primary building block of corals, clams, calcareous algae and many other organism that we grow in our aquarium. Without adequate supplies of calcium these organism will not flourish and will eventually waste away and die.

The ideal value of Calcium in the aquarium is:

     • for the marine aquarium 450 mg/Lt

     • for the planted freshwater aquarium 100 mg/Lt

Because of the importance of calcium, it is necessary to keep inside our marine aquariums, the proper Calcium Level, testing it with an accurate test kit.

HIGHLIGHTS:

Standard sensibility: 25 ppm of Calcium ions.

High number of test per kit: up to 40-50 test depending on Ca level
