Tropic Marin Tropic Marin Pro-Reef Sea Salt

The pharmaceutical grade sea salt especially for modern reef aquaria.

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 lower buffering and the correct pH value serve to stabilize the natural water values, and particularly, the hardness of carbonates, even with the use of calcium reactors. Natural and stable conditions for delicate marine life are achieved only by accurately balancing all influencing factors.

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.
