Tropic Marin Pro-Reef Salt been designed to meet the special requirements of Reef Aquariums. The lower buffering and the correct pH value in Tropic Marin Pro-Reef stabilises natural seawater values, and particularly the hardness of carbonates. Tropic Marin Pro-Reef is the ideal foundation for the care and growth of fish, corals and other invertebrates in Reef Aquariums.
Directions For Use:
To achieve a salinity level of 32-35 ‰ (psu), dissolve 35 ml of Tropic Marin Pro Reef Salt per litre.
Dissolve almost all of the salt in a clean container already filled with the full volume of RO/DI water at a temperature of 73-77°F / 23-25°C, while circulating/stirring the water. Do not concentrate the mixture by adding the full amount of salt to a smaller amount of water.
Note: Always add the salt to the water, never the water to the salt. Making a concentrated mixture will cause a calcium carbonate precipitate to form.
When you have added ALMOST all of the salt and the mixture is fully dissolved and clear, start measuring the specific gravity with a hydrometer or similar instrument.
Keep adding small amounts of salt until the specific gravity is the value you desire. The specific gravity of the sea salt solution should range from 1.025 to 1.027 (at 73-77°F / 23-25°C) and the pH-value should be in the range of 8.0 – 8.4. If all parameters are correct, the salt water is ready to use.
After setting up a new aquarium it takes a few weeks of water being circulated and correct lighting conditions to achieve the biologically stable environment required for the care and breeding of delicate marine organisms.
Parameters: approx. 7° KH, calcium approx. 440 ppm, magnesium approx. 1350 ppm
