Establish ideal mineral/electrolyte balance in planted aquariums. Seachem Equilibrium also aids in maintaining a complete buffering system. This fast dissolving powder is ideally suited for safe and effective re-mineralization of reverse osmosis and de-ionized water. A 300-gram bottle will treat 380 gallons.

For soft water - 1/2 teaspoon per 10 gallons of water. Medium hardness - 2 teaspoons per 10 gallons. Hard water - 3 teaspoons per 10 gallons.

To raise mineral content/general hardness (GH) by 1 meq/L (3 dH), add 16 g (1 tablespoon) for every 20 gallons when setting up an aquarium or when making water changes (add to new water). For optimum solubility, mix in a separate container with a 1 quart 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.

Note: This dosage is based on DI or RO water. For other water, measure hardness (GH) first, and then add Equilibrium 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). Do not use Equilibrium when replacing evaporated water.

Derived from: Potassium Sulfate, Calcium Sulfate, Magnesium Sulfate, Ferric Sulfate, and Manganese Sulfate.

General Information
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. Maintain KH (alkalinity) with an alkaline buffer.

Why It's Different
Unlike competing products, Equilibrium contains no sodium chloride. Both sodium and chloride are not rapidly depleted elements in a planted aquarium and in the case of chloride, can do more harm than good. Competitors' products generally contain primarily sodium chloride (because it is inexpensive), which will raise the electrolyte levels for fish, but can be detrimental to plant growth. In addition, sodium is not a contributing cation to GH levels. Equilibrium contains only calcium, magnesium, and potassium salts, which aid in fish metabolism, but are also highly beneficial to plant growth.
