Seachem Equilibrium 600g

Equilibrium restores and maintains mineral balance and GH and does not contain sodium or chloride. It is ideally suited for use with Rainwater, RO or DI water or any mineral deficient water.

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.

To maintain KH, we recommend Alkaline Buffer.

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.

Equilibrium guaranteed analysis and symptoms of deficiency.

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 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.

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.


  • Soluble Potash (K20) 23.0%

  • Calcium (Ca) 8.06%

  • Magnesium (Mg) 2.41%

  • Iron (Fe) 0.11%

  • Manganese (Mn) 0.06%

Derived from: potassium sulfate, calcium sulfate, magnesium sulfate, ferric sulfate, manganese sulfate.

Elemental potassium is present at a concentration of 195,000 ppm (19.5%).

Fertiliser laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientifically sound method of simple elemental equivalence.
