Seachem Equilibriumâ„¢ is a product for freshwater aquariums that helps adjust and maintain water hardness (GH) and mineral content. It's particularly useful for planted tanks and fish that require specific water conditions.

It is primarily used to increase the mineral content of soft or RO (reverse osmosis) water. Soft water typically lacks essential minerals like calcium (Ca) and magnesium (Mg), which are crucial for the health and well-being of aquarium plants and certain fish species.
