KH Liquid Dupla Marin effectively increases the carbonate hardness and stabilises the pH value in the salt water aquarium. Promotes the growth of all organisms that require calcium carbonate, such as stone corals, fan worms, mussels and various caralline red algae. In natural seawater the carbonate hardness lies between 7 to 9 dKH. 30ml of KH Liquid will increase the KH level in 100 litres of water in the aquarium by 1 dKH.
