Seachem Equilibrium is a mineral supplement specifically designed for planted freshwater aquariums, What It Does Restores General Hardness (GH): Adds calcium, magnesium, and potassium to the water. Promotes Plant Growth: These minerals are vital for healthy root development, vibrant foliage, and overall plant metabolism. Stabilizes Water Chemistry: Helps maintain a stable pH by preventing swings caused by low mineral content. Safe for Sensitive Species: Contains no sodium or chloride, making it safe for shrimp, snails, and delicate plants. Key Features No Sodium or Chloride: Unlike many competing products, it avoids these elements which can harm plants. Ideal for RO/DI Water: Perfect for remineralizing purified water. Available Sizes: 300 g, 600 g, and 4 kg containers. Form: Fine mineral powder. How to Use Dosage: Add 16 g (1 tablespoon) per 80 L (20 US gallons) to raise GH by 3 dGH. Application: Mix with 1 L of water before adding to the tank for better solubility. A slight haze may appear but clears in 15–30 minutes. Frequency: Use during water changes or when GH drops below desired levels. Note: Do not use when replacing evaporated water, as minerals don’t evaporate. Tips Match GH to your target KH (typically 3–6 dKH). Use a GH test kit to monitor levels. For precise dosing, consider using a digital spoon scale.
