Please Note: The entire bag MUST be mixed in one entire batch. This salt is EXACTYLY like the Pro-Reef salt mix in every way with the exception of the physical form of the magnesium, which in this product appears as a small flake. The small flakes of magnesium are visible unlike Pro-Reef consumer packaged products that appear completely homogeneous. The way it dissolves and the resulting salt water solutions are identical.

Tropic Marin® Pro-Reef sea salt has been designed to meet the special requirements of reef aquariums with optimized concentrations of calcium and magnesium, which promote the growth of corals. The adjusted buffering stabilizes pH and alkalinity, even when kalk reactors and other methods of alkalinity supply are used. Natural and stable conditions for delicate marine life are achieved only by accurately balancing all influencing factors. With Tropic Marin® Pro-Reef you can maintain the alkalinity in a 7-8° dKH range.

Tropic Marin® Pro-Reef is thus the ideal foundation for the care and growth of fish, corals and other aquatic invertebrates in modern reef aquariums. Use seawater prepared with Tropic Marin® Pro-Reef for regular water changes in your seawater aquarium, to start a new aquarium and to re-equilibrate the pH of a tank.
