The trace elements remain perfectly soluble in the mixed crystals. A high proportion of buffer substances stabilize the aquarium and prevent pH fluctuations. Tropic Marin ® Sea Salt CLASSIC thus forms an ideal basis for all living organisms in a saltwater aquarium.
To obtain a salinity of 32 to 35‰ (practical salinity unit), dissolve 35 ml of Tropic Marin ® Sea Salt CLASSIC per liter of water in a container while stirring. The sea water thus prepared can be used as soon as the salt has completely dissolved and the solution is clear. The relative density of the saline solution should be between 1.025 and 1.027 at a temperature of 25°C. For a new aquarium, a biologically stable environment is obtained in a few weeks under the effect of lighting and water recirculation, conducive to the development of marine species. Once a week, a partial renewal of the water (approximately 10%), using the Tropic Marin ® Sea Salt CLASSIC solution, allows you to maintain a satisfactory level of quality for your farms. Use the new dosage calculator for easy determination of the necessary amount of sea salt for your aquarium.
