To raise mineral content/general hardness (GH) by 1 meq/L (3 dH), add 16 g (1 tablespoon) for every 80 L (20 US gallons) when setting up an aquarium or when making water changes (add to new water). For optimum solubility we recommend mixing with 1 L (1 qt.) of water (the resulting mixture will have a white opaque appearance). When this mixture is added to the aquarium it will impart a slight haze that should clear within 15–30 minutes. HINTS: Do not use Equilibrium™ when replacing evaporated water. This dose is based on DI or RO water; for other water, measure hardness (GH) first, then add according to need. For precise dosing, use the Seachem Digital Spoon Scale.
Plant preferences vary, but a general guide is about 1–2 meq/L (3–6 dH) or match the existing or target carbonate hardness (KH), which, ideally, is also about 1–2 meq/L (3–6 dKH). Equilibrium™ will compact with age, but remains effective.
