Measuring, regulating and testing

Water value in the marine aquarium is a science in itself which might be especially difficult for the beginners in the starting. In addition to the density in the marine tanks – one of the most important parameters is the measurable values of carbonate hardness, calcium, magnesium as well as the nitrate value and the phosphate value in water should be tested regularly easily with tests. In this category of online shop you will find professional water tests, density measuring devices as well as technical tools like GHL aquarium computer and refilling systems.
