Seachem Equilibrium 600g
A remineralizer for RO water designed for planted tanks.
Uses: This product is used for remineraling Reverse Osmosis water, distilled water, or very soft water. These types of water contain none of the minerals and other trace elements that aquatic life needs to grow. Equilibrium™ should be added whenever you do a water change with purified water to support your aquatic plants and animals. This is the remineralizer that Aquatic Arts uses for 100% of our planted aquariums, both personally and professionally.
From the manufacturer: Equilibrium™ is specifically designed to establish the ideal mineral content for the planted aquarium. Equilibrium™ contains no sodium or chloride (which can be detrimental to a planted aquarium at elevated levels). Equilibrium™ is ideally suited for use with RO (reverse osmosis) or DI (deionized) water or any mineral deficient water. Equilibrium™ raises the essential mineral/electrolyte content (General Hardness) of the water to balance with and promote stability of the carbonate hardness.Directionsc from the manufacturer: To raise mineral content/general hardness (GH) 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 (GH) 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).
