“Reconstitute RO Dry” is a high quality, multi-component, broad spectrum mixture of all mineral ions including General Hardness (GH), alkalinity (KH) and all major, minor and trace minerals required for optimum health and longevity of freshwater fish, invertebrates and plants. When mixed with filtered water prepared by reverse osmosis, distillation, or deionization, it will convert those filtered waters into a natural environment in which all aquarium inhabitants will thrive. It has been used to raise discus and other freshwater fish, as well as keep whole systems in breeder, public and home aquariums. Continuum Aquatics is owned and operated by Jack Kent.
