Water conditioner for the safe increase of the carbonate hardness (KH) in fresh and salt water. 5 ml sera kH-plus increase the carbonate hardness in 40 litres aquarium water by 1 dKH. The carbonate hardness in freshwater community aquariums should be 5 - 10 dKH, in saltwater aquariums 8 - 12 dkH. First check the carbonate hardness by means of a kH-test. Then add sera kH-plus directly into the aquarium. We recommend increasing the carbonate hardness by maximum 2 dKH per day. |
