Info: Seachem Brackish Salt™ Dosing Instructions

Use when setting up an aquarium and when making water changes. To add salt to an established tank, do so gradually. It is best to dissolve the salt in freshwater before use. Avoid using salt when simply replacing evaporated water.

• For live bearers (such as guppies, swordtails, platies, some mollies), use 20 g (~1 tablespoon) for each 40 L (10 US gallons).
• For estuary fish from the Yucatan or Sri Lanka (Archers, Chromides, some mollies), use 15 g (~2 teaspoons) for each 12 L (3 US gallons).
• For estuary fish from Thailand, Cambodia, Borneo, or Sumatra (Datnioides), use 40 g (~2 tablespoons) per 12 L (3 US gallons).
• For scats, use up to 80 g (~4 tablespoons) per 12 L (3 US gallons). This dose is not for planted aquaria.
• For mixed populations, use an average dose, representative of species present. For specific information on your fish, check with your dealer or other reference source.
• For general aquarium salt use (either for mineral replacement or disease control), use 20 g (~1 tablespoon) for each 40 L (10 US gallons).
