![Tropic Marin Presents T Marin Kit Salt/Fresh Ammonia Saltwater Test. For the Determination of the Ammonia/Ammonium Concentration in Fresh and Saltwater. The Ammonium-Ion (Nh4+) is the Result of Nitrogen Mineralisation and Exists with Ammonia (Nh3) in an Equilibrium Depending on the Ph-Value. Nitrogen Organically Bound in Food Remains and Excrement is Converted by Bacteria and Set Free in the Form of Inorganic Ammonium Ions. An Ammonium Value that is Too High Impairs the Respiration and Blocks Vital Biological Functions in Livestock with Potentially Devastating Effects. With this Test, the Ammonium Concentration can be Determined from 0.01 to 3 Mg/L and - with Known Ph-Value - be Converted to the Ammonia Concentration with the Help of a Chart. The Test Reagents are Sufficient for Approx. 50 Tests. [35192]](http://cdn.petcarerx.com/img/PrdImg/408x408/22644_001_xl.jpg)

![Tropic Marin Presents T.Marin Test Kit Salt Calcium Saltwater. For the Determination of the Calcium Concentration in Saltwater. Calcium is One of the Most Important Components of Saltwater and Largely Determines the Growth Rate of Organisms, which Form Calcareous Skeletons Like, for Example Stony Corals and Calcareous Algae. In the Marine Aquarium, a Regular Addition of Calcium Ions is Necessary because of the Constant Decrease of the Calcium Concentration Caused by the Metabolism of the Organisms and by Precipitation. Careful Supervision of the Calcium Content in the Marine Aquarium Ensures Optimal and Lifelike Living Conditions for all Calcareous Organisms. With a Sensitivity of 4 Mg/L, the Calcium-Test by Tropic Marin is the Most Accurate Calcium Test Available. Special Reagents Intentionally Make Use of the High Magnesium Concentration of the Seawater, which Usually Interferes with Aquarium Calcium Tests, and Thus Guarantee the Outstanding Dependability of the Results. For Approx. 50 Tests. [35197]](http://cdn.petcarerx.com/img/PrdImg/408x408/22649_001_xl.jpg)
