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
