The Ideal Foundation

Tropic Marin Classic Sea Salt Mix is perfect for aquariums that house even the most sensitive species. The natural balance of elements is made using pharmaceutical salts and free from artificial additives, nitrates, and phosphates, allowing the salt to mix fast and crystal clear. If you are starting a new tank or using Tropic Marin Classic Salt for general water changes, the appropriate balance of bicarbonates will help re-equilibrate the pH of your tank while providing a balanced ratio of all other major and minor trace elements. 

  • Mixes Fast
  • Helps stabilize pH
  • Made from pharmaceutical materials
  • Contains all major and minor elements
  • Perfect for fish only or coral reef aquariums
  • Does not contain unwanted nitrates or phosphates

We suggest starting with 1/2 Cups of Tropic Marin Sea Salt Classic per 1 Gallon of RODI water. For the best results, the water should be circulating and at a temperature of 73-77 °F. Once the water is up to temperature and circulating, slowly adding the appropriate amount of salt will allow it to fully dissolve quickly without creating any concentrated areas where precipitation may occur. 

When you have added almost all of the salt and the mixture is fully dissolved and clear, start measuring the specific gravity with a refractometer 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.

Note: Always add the salt to the water, never the water to the salt.
