The carbonate hardness (KH) is used to stabilize the pH value.
Avoid sudden changes in pH, caused for example by organic decomposition in the aquarium and ornamental pond or consumption of carbon dioxide by plants.
A carbonate hardness is too low because of sudden changes of pH value.
KH values between 5 ° and 10 ° create optimal conditions in the aquarium and stable communities and provide the foundation for a luxuriant growth of plants.
Cichlids of Lakes Malawi and Tanganyika require higher values.
Marine aquarium KH value must be over 12 ° DHK.
By Sera KH-plus (in the aquarium, marine and fresh) or the Sera KH pond (in the ornamental pond) you can adjust very precisely the carbonate hardness.
If you want to change the pH and / or want to lower a high value of carbon (eg 21 ° DHK aquarium community), you can use the overactive Sera Granulated peat (freshwater aquarium) and the Sera of Biogranulato peat (in the ornamental pond).
