Seachem Equilibrium - 4KG Seachem Equilibrium - 4KG is a bulk-size planted aquarium mineral supplement for remineralizing RO, DI, soft, or mineral-deficient freshwater while raising general hardness (GH). Seachem Equilibrium for Bulk RO/DI Remineralizing The 4 kg size is suited to larger planted aquariums, fish rooms, maintenance accounts, and frequent water-change routines where purified or low-mineral water needs consistent GH adjustment. Equilibrium adds plant-relevant minerals without sodium chloride. Planted Tank GH Support Benefits Raises general hardness in planted freshwater aquariums. Ideal for regular remineralization of RO or DI water. Bulk format is practical for larger aquariums and repeated water changes. Contains calcium, magnesium, and potassium salts for planted tank mineral support. Contains no sodium chloride and does not add phosphate. Supports mineral balance while KH is managed separately with an appropriate buffer when needed. Seachem Equilibrium GH Supplement Details Product type: Planted aquarium mineral supplement Primary function: Raises general hardness (GH) Best use: RO, DI, soft, or mineral-deficient freshwater Guaranteed analysis includes: Soluble potash, calcium, magnesium, iron, and manganese Package size: 4 kg Directions for Seachem Equilibrium To raise GH by 1 meq/L or 3 dH, add 16 g or 1 tablespoon for every 80 L (20 US gallons) when setting up an aquarium or preparing new water for a water change. For optimum solubility, mix with about 1 L (1 qt.) of water before dosing. The mixture may appear white and can create a slight haze after addition that should clear within 15 to 30 minutes.
