Brackish Salt

  • Creates ideal environment for livebearers and brackish fish
  • Safe for plants
  • Effective alternative to the sodium chloride based aquarium salts so prevalent

Seachem’s Brackish Salt™ is a chemically sound blend of salts designed to replicate the native environment of live bearers and other brackish estuary fish without adversely impacting aquatic plants when used at regionally specific recommended dosage. The salt is also well suited for routine aquarium freshwater use. It does not impact pH or provide buffering.

Unlike other aquarium salts currently available to the hobbyist, Brackish Salt™ is more than just a simple sodium chloride product. These other salts can burn leaves and roots in a planted aquarium. However, Brackish Salt™ does not cause this type of damage, and actually provides many nutrients crucial to healthy plant growth. Dosing of Brackish Salt™ allows for specific duplication of different brackish water environments found worldwide (such as the waters of Sumatra or the waters of Borneo). Brackish Salt™ can also be dosed for general brackish water community aquariums and general freshwater community aquarium. Brackish Salt™ is a safe and effective alternative to the sodium chloride based aquarium salts so prevalent

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).

A: Used as directed, Brackish Salt™ will not cause harm to plants. Brackish Salt™ is a blend of salts that contains a minimal amount of sodium chloride unlike other freshwater aquarium salts which are nothing but sodium chloride. Elevated levels of sodium and chloride will harm plants. It is the minimal amount contained in Brackish Salt™ that makes this product safe for plants.
