Seachem live bearer/brackish aquarium 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 on 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. For low range pH control Use Acid buffer, discus buffer, South American Cichlid buffer 4. 5, or Acid regulator. Use neutral regulator, Central American Cichlid buffer or South American Cichlid buffer 7. 0 for neutral pH. For high range pH control Use alkaline regulator, alkaline buffer or Tanganyika buffer.
