EquilibriumTM is specifically designed to establish the ideal mineral content for the planted aquarium. EquilibriumTM contains no sodium or chloride (which can be detrimental to a planted aquarium at elevated levels). EquilibriumTM is ideally suited for use with RO (reverse osmosis) or DI (deionized) water or any mineral deficient water. EquilibriumTM 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 BufferTM.

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. EquilibriumTM contains only calcium, magnesium, and potassium salts, which aid in fish metabolism, but are also highly beneficial to plant growth


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). EquilibriumTM 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 EquilibriumTM 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).

Another solid Seachem product. I live in Scotland where the water is often soft and mineral deficient so it is necessary to boost the GH. I will soon be moving to using RO water so conditioning the water with this product will become very necessary.
