To adapt the pH value to the needs of the fish and invertebrates in fresh and saltwater aquariums Rapid raising of the pH value and stabilisation through increase of the carbonate hardness Use in freshwater: can be used as often as needed to raise the carbonate hardness in too soft water to the desired value. Maximal increase of the pH value to 8.5 Use in saltwater: adjusts the carbonate hardness to the natural ocean value of 10 to 12 °d KH and thus adjusts the required pH value of 8.0 to 8.4 Contents: 1 bottle pH/KH increaser. To use: 10 ml/40 l water. Results into an increase of approximately 1° dKH
