Seachem Brackish Salt 600g — Electrolyte & Mineral Buffer To Recreate Natural Brackish Water Chemistry in Aquariums Having Estuarine Species Like Pufferfish, Monos, Etc
Seachem Brackish Salt 600g (SKU: 725178-223) is a specialised mineral salt blend formulated to recreate natural brackish water chemistry in home aquariums. Estuarine species—such as Pufferfish, Monos, Scats, Archerfish, and Mollies—require water containing specific ratios of sodium, potassium, calcium, and magnesium. Brackish Salt supplies these essential minerals without elevating hardness or pH beyond natural estuarine levels.
The 600g tub offers double the volume of the starter size, providing extended value for medium brackish displays. Regular use supports osmoregulation, reduces metabolic stress, and improves colouration across brackish fish species.
Usage & Application
When to Use
- Medium Brackish Systems: Recreates estuarine conditions in aquariums between 100 and 300 litres.
- Livebearer Conditioning: Supports health and reproduction in Mollies, Endlers, and Guppies.
- Specific Gravity Control: Adjusts specific gravity between 1.002 and 1.008 for brackish species.
Dosing & Administration Guide
- Light Brackish (Mollies, Guppies): Add 12 g (1 tablespoon) per 40 L of water (SG ~ 1.002).
- Medium Brackish (Puffers, Archers): Add 24 g (2 tablespoons) per 40 L of water (SG ~ 1.005).
- Preparation: Pre-dissolve required salt in fresh water and confirm specific gravity with a refractometer.
