Seachem Brackish Salt
Seachem Brackish Salt (300g)
Seachem Brackish Salt provides all the minerals necessary to create authentic brackish water conditions for fish that live in estuaries, mangroves, and tidal zones. Unlike using marine salt mixes for brackish tanks, Brackish Salt is specifically formulated to achieve low-to-moderate salinity levels (SG 1.002–1.015) without over-boosting specific marine ions. It provides the correct balance of sodium, potassium, calcium, and magnesium at brackish ratios. Ideal for brackish species including Archers, Monos, Scats, Puffers (such as Green Spotted Puffers and Hairy Puffers), Figure-Eight Puffers, and mudskippers.
Key Features
