Seachem Equilibrium 300 g

Seachem Equilibrium 300 g is a freshwater mineral supplement designed to restore and maintain general hardness, also known as GH, in planted aquariums and other freshwater systems. It replenishes essential minerals such as calcium, magnesium, and potassium that may be missing from soft, RO, DI, or distilled water.

Equilibrium is especially useful for planted aquariums where mineral balance supports healthy plant growth, strong root development, and vibrant foliage. It contains no sodium or chloride, making it a strong choice for aquarists who want to remineralize freshwater without adding unnecessary salts.

  • Supplies Essential Minerals: Adds calcium, magnesium, and potassium for freshwater aquarium health.
  • Great for Planted Tanks: Supports plant growth, root development, and healthy foliage.
  • No Sodium or Chloride: Remineralizes freshwater without adding sodium chloride.
  • Shrimp & Snail Friendly: Helps support mineral levels needed by many freshwater invertebrates.
  • Does Not Significantly Affect pH or KH: Raises GH without strongly altering alkalinity.
  • 300 g Size: Convenient for planted aquariums, shrimp tanks, and routine water changes.

Directions for Use

Add 1 tablespoon, approximately 16 g, for every 80 L / 20 US gallons to raise general hardness by approximately 3 degrees, or 54 ppm. Dose according to the product label and your aquarium’s current GH level.

For best results, dissolve Equilibrium in water before adding it to the aquarium, or distribute it evenly in a high-flow area. Test GH regularly and adjust dosing based on your target water parameters.

Important Use Notes

  • Test GH before and after dosing.
  • Adjust mineral levels gradually to avoid stressing fish, shrimp, or plants.
  • Use during water changes or when GH drops below your target range.
  • Equilibrium raises GH but does not significantly raise pH or KH.
  • Research the preferred GH range for your fish, shrimp, snails, and plants.
  • Keep out of reach of children and pets.

Why Use Seachem Equilibrium?

RO, DI, distilled, and very soft tap water may lack the minerals needed for healthy freshwater aquariums. Plants, shrimp, snails, and many fish rely on proper mineral balance for normal biological function, growth, molting, and overall stability.

Seachem Equilibrium helps restore important minerals without adding sodium or chloride, making it a useful supplement for planted aquariums and freshwater systems that need GH support.
