The ROYAL NATURE Calcium Professional test will allow you to accurately determine the calcium content of the water in your marine aquarium . The color of the indicator changes very clearly from pink to blue. One box can perform around 50 analyses .
Royal Nature produces a very pure Calcium salt . This Hydrated Calcium Chloride is the ideal solution to increase the concentration of dissolved Calcium in the aquarium.
Being able to perform tests intuitively was a major concern for Royal Nature . Its chemists have prepared a calcium test for you in just two steps. It was also essential to have clear color changes in the titration, to prevent users from having an error-prone reading of the test.
Each test uses a two-part chemical reaction and a syringe to add water until the final color is reached. Royal Nature also guarantees 50 tests on each calcium (Ca) test box.
Royal Nature 's Ca test method is relatively novel and is based on direct titration where we add seawater to the chemical solution. This solution reacts first with Ca, then with Mg (Magnesium). Finally, it reacts to the color indicator of the metal ion, which is the stage of color evolution. The color of the indicator changes very clearly from pink to blue. Royal Nature has the ability to produce very small quantities of calibration solutions, thus guaranteeing the accuracy of their tests.
