A mixture of chemicals for establishing in freshwater aquariums a standard ion concentration complying with a biotope

摘要

The present invention relates to a mixture of chemicals for the preparation of aquarium water which chemically corresponds to the native biotopes of ornamental fish and aquatic plants which are held in aquarium water. The mixture is composed by of 12.5 mg calcium carbonate (carbonate of lime, CaCO₃), 12.5 mg magnesium sulfate (Epsom salts - MgSO₄.7H₂O), 7.5 mg potassium chloride (KCl)) and 10.0 mg sodium carbonate (sodium bicarbonate - NaHCO₃), with a certain tolerance range as an additive per 1000 ml pure water.
