Used for years by scientific laboratories, professionals and hobby aquarists all over the world. With pharmaceutical grade salts, all trace elements of natural seawater, in the exact proportions found in nature and being free from nitrates, phosphates and other unwanted chemicals, it provides a strong buffering system and a natural environment for the care of fishes, marine plants and invertebrates in any aquarium.
Marine life can only flourish in a healthy environment. For over 30 years, Tropic Marin Sea Salt has been the only sea salt in the world produced under scientific supervision.
Directions for Use: Use saltwater prepared with Tropic Marin Sea Salt for regular water changes in your saltwater aquarium, to start a new aquarium and to re-equilibrate the pH of a tank. Add the required amount of Tropic Marin Sea Salt to water in a clean container while circulating and aerating. The resulting saltwater is ready for use as soon as the salt is completely dissolved. At a temperature of 73-77°F (23-25°C), the specific gravity of the saltwater should range from 1.022 to 1.025.
A weekly, partial water change, replacing 10% of the total water volume with saltwater prepared with Tropic Marin Sea Salt, will help to maintain the water quality that your livestock needs for good health.
