Seachem Equilibrium restores and maintains mineral balance and GH.

Does not contain sodium or chloride like competing products.

Ideally suited for use with RO or DI water or any mineral deficient water.

What is Seachem Equilibrium?

Your plants use minerals from the soil to build the complex molecules needed to survive and grow. Therefore poor plant growth may be due to a deficiency of one or more minerals.

We have specially designed Seachem Equilibrium to achieve the ideal mineral content for the planted aquarium. It contains no Sodium Chloride as both Sodium and Chloride are elements which do not quickly deplete in an aquarium. Chloride can actually do more harm than good and some products on the market use a high percentage of Sodium Chloride (salt) in their mixes as it is cheap to produce.

Reverse Osmosis

Seachem Equilibrium is ideally suited to RO water (reverse Osmosis) or DO (deionized) water.

Seachem Equilibrium raises the essential mineral/electrolyte content (General Hardness) of the water in your tank to balance with and promote stability of the carbonate hardness. To maintain KH, we recommend Alkaline Buffer.

SEachem Equilibrium contains only calcium, magnesium, and potassium salts which aid in fish metabolism. It is also highly beneficial to plant growth.


If you want to raise mineral content/general hardness (GH) by 1 meq/L (3dH), add 16g (1 tablespoon) for every 80L when setting up an aquarium or when making water changes (add to new water).

For the most soluble outcome mix with 1L of water (the resulting mixture will have a white opaque appearance). When this mixture is added to the tank it will impart a slight haze that should clear within 30 minutes.

HINTS: Do not use Seachem Equilibrium when replacing evaporated water. This dose is based on DI or RO water; for other water measure the hardness (GH) first, then add according to your needs. For precise dosing use the Seachem Digital Spoon Scale.

Plant preferences vary but as a general guide about 1–2 meq/L (3–6dH) or match the existing or target carbonate hardness (KH) which, ideally, is also about 1–2 meq/L (3–6dKH). Seachem Equilibrium will compact with age but remains effective.
