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.
