Seachem Equilibrium 300g
Directions for use:
To raise mineral content/general hardness by 1 meq/L (3 dH), add 16 g (1 tablespoon) for every 80 L (20 gallons) when setting up an aquarium or when making water changes (add to new water). Equilibrium can be added straight; although 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 first, then add according to need. 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).
